BN00100.100 - Life Cycle Analysis - Reinforced concrete slab system - 09.03.2010

1. INTRODUCTION

1.1 Initial situation and objectives

The voided slab system developed by Cobiax Technologies AG is based on the use of void formers. Throughthe reduction of reinforced concrete in static non-stress areas there is a carcass optimization. Thisoptimization results in a reduction of toxic pollutants. In order to clearly quantify this positive impact on theenvironment CSD was commissioned to elaborate a Life Cycle Analysis. This analysis is aimed to provide basicdata for an environmental life cycle assessment and therefore provide planners with a basis of valuation toimplement a sustainable and holistic optimization of building concepts.

1.2 Boundary conditions

Material flows originated by structural engineering represent an economic main part. Analyzing theconstruction dimensions of reinforced concrete structures, it can be noted that a large percentage of thebuilding mass is needed for the constructive carcass.

Depending on the cubic volume, the structural shape and the occupancy, the following values can bespecified:

Constructive carcass: material ratio about 66% Building services heating/cooling: material ratio about 13% Structural interior work: material ratio about 12% Constructive cladding surface area: material ratio about 9%

In reinforced concrete buildings a mass fraction of about 45-55% is assumed for the slab elements.Considering these boundary conditions, a significant savings potential in the ecologicaloptimization of slabs systems can be noted.Through the identification of a characteristic value “dead load to live load”, a first estimate of thematerial efficiency of slab systems can be deduced:

Solid reinforced concrete slab:

Figure 1: Solid reinforced concrete slab

For a reinforced concrete slab with a slab depth of for example 30 cm the following characteristic values areobtained:

dead load: about 7,4 kN/m²live load: about 5 kN/m²

characteristic value dead load/live load = 1,48

Cobiax slab, reinforced concrete slab as voided slab system:

Figure 2: Reinforced concrete slab system Cobiax

For a reinforced concrete slab with the Cobiax System the following characteristic values are obtained:

dead load: ca. 6,0 kN/m²live load: ca. 5 kN/m²

characteristic value dead load/live load = 1,2

2. EVALUATION CRITERIA

2.1 Indicators

In the analysis of environmental indicators, both the pollutant equivalents for the creation process and for theperiod at the end of the life cycle were considered (End of Life). In the ecological analysis, the followingindicators were evaluated:

Global Warming Potential – GWP

Description:

The Global Warming Potential is a measure for the estimated contribution of a substance to the warming ofthe near-surface air, the so called greenhouse effect. The contribution of the substance is indicated as GWP-value in relation to the greenhouse potential of carbon dioxide (CO2).

Ozone Depletion Potential – ODP

Description:

Ozone, which is only present in the atmosphere in low concentrations, has a great significance for life onearth. Ozone absorbs short-wave UV-rays and emits longer wavelength radiation omnidirectionally. Theozone layer shields the earth from a large part of the UV-radiation, prevents excessive warming of the earth’ssurface, and contributes to protecting humans as well as flora and fauna from UV-A and UV-B radiation. Theaccumulation of R11-equivalent in the atmosphere contributes to the destruction of the ozone-layer.Consequences are e.g. tumour generation in humans and animals, as well as disruption of photosynthesis.

Photochemical Ozone Creation Potential – POCP

Description:

The photochemical ozone creation potential is the mass-based equivalent of destructive trace gases, e.g.nitric oxide and hydrocarbons, which in combination with UV-radiation contribute to the formation of near-surface (tropospheric) ozone. The resulting human- and eco-toxic contamination of the near-surface air iscalled summer-smog. It adversely affects the respiratory system and damages plants and animals. Theconcentration of near-surface ozone is regularly assessed by air monitoring stations, shown in load maps andpublished.

Concrete structure

Acidification Potential – AP

Description:

The increase of the concentration of H-ions in the air, water and soil is called acidification. Sulphur andnitrogen compounds from anthropogenic emissions react in the air to form sulphuric and/or nitric acids thatfall to the earth as “acid rain” and negatively impact soil, water bodies, creatures and buildings. There mayalso be a release of toxic cations which attack root systems, lead to an inappropriate nutrient supply fororganisms and perturb the water balance. The sum of the individual acidification impacts creates forestdieback. In surface waters with a low chemical buffering capacity it also causes fish mortality. Furthermore,acidic precipitations corrode historical sandstone buildings.

Eutrophication Potential – EP

Description:

Eutrophication describes the transition of water bodies and soil from a nutrient-poor (oligotrophic) to anutrient-rich (eutrophic) state. This state is mainly caused by supplying phosphor and nitrogen compounds.These compounds can get into the environment via fabrication of building materials and via washing-off ofcombustion emissions. The change in the availability of nutrients increases for example the formation ofalgae in water bodies which, among other things, can lead to higher fish mortality.

Non-Renewable Primary Energy Demands – PEnr

Description:

Primary energy is the energy that is available from naturally existing energy sources. It includes non-renewable energies such as black coal, brown coal, petroleum, natural gas, and uranium.

Total Primary Energy Demands and Proportion of Renewable Primary Energy – PEtot

Description:

Primary energy is the available energy of natural sources. Among the non-renewable primary energies areblack coal, brown coal, petroleum, natural gas and uranium; and among the renewable energies arebiomass, solar radiation, geothermal energy, hydropower, and wind energy. The sum of both energy sourcesis referred to as total primary energy demand.

2.2 Object of study

The present LCA assessment compares a conventional reinforced concrete slab system (see Figure 1) with areinforced concrete slab system with Cobiax void formers (see Figure 2). The mass reduction of the Cobiaxslabs is achieved through the use of void formers in the statically unclaimed slab center. Thus both slabsystems have the same live load. The following slab depths were compared (see Table 1):

Slab depth [cm] 18 20 25 28 30 35 40 45 50 55 60

2.4 Data description for the Life cycle impact assessment

The Life cycle impact assessment is done based on the data of „Ökobau.dat“ (Source: Federal Ministry ofTransport, Building and Urban Development, Germany).The used data basis as well as a capsule summary is given in appendix D.

2.5 Sensitivity analysis

A sensitivity analysis was conducted for the following assumptions and data from third parties:

Transport route raw material(concrete, reinforcement steel,synthetic components)

The sum of all transportation expenses is for the acidificationpotential < 5%, for all other indicators < 3%. A deviation of 20% inthe assumed transport route has a maximal percental impact of atenth. Moreover, in comparative analysis only the difference inquantity of materials and their transportation expenses are ofimportance. Thus, no impact can be detected.

Transport route rubble As the impact of transportation expenses is not significant, thoseexpenses as well as the differences in material mass can be waived.

Energy data for plastics processing The percental content of this characteristic value lies between 0,47and 2,41 The average of all investigated slabs is 1,6%. So differingenergy data do not have a significant influence.

Table 3: Sensitivity analysis

3. RESULTS

The results of the life cycle assessment are given in Appendix A Table 1 to Table 11. A summary of thepercentages compared with a reinforced concrete without void formers is presented in Table 1 and inDiagramm 1. It can be shown that the savings potential depends on the slab depth. The average reductioncompared to a solid reinforced concrete slab can be estimated at 20%.

4. CONCLUSIONS

The implementation of void formers into a slab system increases the efficiency in material use. Thisimprovement of the carcass is the result of following effects.

Economization of material through the use of void formers

Reduction of the steel ratio through a lower dead load

Savings in material through reduction of dead load and a lower slab depth in consequence (notconsidered in this study)

Economization of material used in the foundation (not considered in this study)

Reduction of dimension and accordingly of the load- bearing components like for example shoring(not considered in this study)

Reduction of facing area through lower slab depths (not considered in this study)

The mass- fraction of the material used in slab systems to the total mass of a reinforced concrete building isabout 45%-55%. The mean reduction of toxic pollutants by 20% therefore results in a savings capacity oftoxic pollutants of about 9%-11% for the entire building construction.

Making use of enhancement potential in building materials will become more important in the future. Takinginto account a period of 50 years, building materials are responsible for 40% of ecologically relevantemissions. This value can be applied if following phases are considered in a life cycle analysis:

Fabrication/ new construction

Maintenance

Cleaning

Disposal

D:\002_CSD_Projekte\1_Berlin\BN00100_Cobiax\100_LCA_Bewertung\Übersetzungen\Bericht _Cobiaxbewertung_English.doc

The remaining 60% of pollutant emissions are caused by energy carriers used for the conditioning ofbuildings (heating, air ventilation, cooling, lighting). With an increase in energetic optimization theimportance of improvements in building materials and the use of resource efficient materials will increase aswell.

Der Datensatz repräsentiert die Stahlproduktion in Deutschland. Er basiert auf denwesentlichen Prozessen innerhalb eines Elektrostahlwerks. Hauptprozess hierbei istdas Schmelzen von Schrott in einem Elektroofen (EAF) unter Energiezufuhr(Stromverbrauch). Wesentlichstes Rohmaterial des EAF ist Eisenschrott, welchersowohl innerhalb der Produktion im Werk anfällt (Verschnitt) aber auch ausVerschnitten von Stahlherstellern stammt (z. B. aus dem Fahrzeugbau) oder Schrottvon Endnutzern (End-of-Life Produkte) darstellt. Wie im gemischten Stahlwerk mitHochofen und Konverter dient Kalkstein zur Aufnahme von ungewünschtenStahlkomponenten. Kalkstein dient als ein Zusatzstoff zur Schlackebildung, ebensowird Kohle (Kohlenstoff) als Reduktionsmittel verwendet. Transporte jeglicherMaterialfraktionen sind im Datensatz berücksichtigt. Zur Herstellung vonKohlenstoffstahl und niedrig legiertem Stahl werden die folgenden Prozessschrittedurchlaufen: Rohmaterialhandhabung und Lagerung, Ofenbeschicktung mit undohne Schrottvorheizung, EAF Schrottschmelzen, ?Stahl- und Schlackenabstich,Pfannenofenbehandlung zur Qualitätssicherung, Ascheverwertung/Entsorgung undschließlich das Stranggießen. Output des Stranggießens ist Bramme aus Stahl. Diesewird anschließend weiterverarbeitet zu Stahlstäben mit Hilfe eines Ziehvorgangs. DerVerbund des Bewehrungsstahls mit dem umgebenden Beton bestimmt maßgeblichdie Qualität von Stahlbeton. Zur Verbesserung des Verbundes ist derBewehrungsstahl gerippt.

Es wurde davon ausgegangen, dass große Geräte wie Heizkessel, Klima- undLüftungsanlagen oder Fahrstühle zu 95% einem Recycling zugeführt werden. FürRohre oder Kabel, die oft unterputzt sind wurde eine Recyclingrate von 90%angenommen. Die Recyclingquoten beziehen sich ausschließlich auf Metalle undKunststoffe. Für mineralische Materialien wie Mineralwolle, Beton oder Keramikwurde eine Ablagerung auf einer Inertstoffdeponie angenommen. Es wurdeangenommen das der Anteil an Metallen und Kunststoffen, der nicht einem Recyclingzugeführt wird (5-10%) ebenfalls auf einer Inertstoffdeponie entsorgt wird (z.B.Kabelreste oder Rohrstücke im Bauschutt). Für die Kunststoffe wird davonausgegangen, dass aufgrund der oft langen Lebensdauer und den verbundenenVerunreinigung nicht von einer stofflichen Verwertung ausgegangen werden kannund daher die Kunststoffe einer energetischen Verwertung inMüllverbrennungsanlagen (MVA) zugeführt werden. Für die Müllverbrennung wurdeein MVA-Modell mit durchschnittlichen europäischen Emissionswerten undEnergieproduktion verwendet. In Abhängigkeit des zu verbrennenden Kunststoffeswurden unterschiedliche Prozesse mit den entsprechendenElementarzusammensetzungen verwendet. Die Datensätze wurden inZusammenarbeit mit der Confederation of European Waste-to-Energy Plants(CEWEP) erstellt und sind auf der Homepage der European Platform on LCA [EC2008] verfügbar. Der aus der Kunststoffverbrennung erzeugte Strom sowie dieerzeugte thermische Energie wurden mit dem europäischen Strom-bzw. Wärmemixgutgeschrieben. Die Gutschriften für das Recycling von Metallen oder derenergetischen Verwertung von Kunststoffen, sowie die mit der Verwertungverbundenen Emissionen und Ressourcenverbräuche (Energie für Einschmelzen,Verbrennungsemissionen, Deponie) sind in den Datensätzen enthalten.

DieseMengen wurden der recycelten Stahlmenge vor Zuführung in die Einschmelzungabgezogen, um keine Überwertung der Gutschriften zu erzeugen. Die Gutschriftwurde dann entsprechend mit primärem Stahl durchgeführt. Gutschriften für dasRecycling von seltenen Erden oder Quecksilberemissionen aus Leuchtstofflampenkonnten wegen fehlenden Daten nicht berücksichtigt werden. Als Transportdistanzzwischen Gebäude und Recyclinghof bzw.
