Experimental research on building material - ceramsite concrete

摘要

In order to study the strength and crack resistance of lightweight concrete, this paper made the concrete using lytag as coarse aggregate block, and join in the block of polypropylene fiber in order to improve its strength and crack resistance. Use control variable law for reference block, the following conclusions: through the experiment, when the standard test block ceramsite dosage is 1000 g, dosage of fiber types 6 mm for 70 g can achieve optimal crack resistance and maximum compressive strength, and with continued increase in the amount of ceramsite concrete compressive strength of block is on the decline.
