REPORT ON WATERPROOFING TEST DONE ON AAC BLOCKS USING

DIFFERENT CHEMICALS

Introduction:

Water proofing is done on AAC ( Aerocon) blocks which has > 40 % water absorption, using different type of water proofing chemicals. Application is done by different vendors.

Aerocon blocks are cut into 100X100X100 mm samples and initial weights of the samples are taken. Then water proofing is done on these blocks using different chemicals supplied by applicator. Samples are allowed to dry for one day and dry weight of the treated sample is recorded before immersing in water.

Samples are immersed in water for 24 hours and weight of the cube samples are recorded when they are in surface dry condition.Then, the percentage absorption of treated sample is been calculated and the average of three samples is the % absorption of water by the treated Aerocon block sample.
