Study of Mechanical Properties and Physical Properties of Rubberized Portland Cement Concrete

摘要

This test summers up the research situation of rubber powder modifier. According to tests of density, flexural strength, compressive strength and cleavage strength, this test analyzes the basic mechanical properties and the variation of rubberized portland cement concrete which is mixing the silica fume modifier. The results show that the flexural strength, compressive strength and cleavage strength of concrete may increase when silica fume concrete admixture modifiers is mixed in cement concrete. The workability, density, flexural strength, compressive strength, ratio of compressive strength and cleavage strength of rubberized portland cement concrete gradually reduced with the increase in dosage of rubber. The rubber particles mixed with concrete which can when the rubber particle size is not more than 30% of the dosage of coarse aggregate, the fine pavement of rubberized portland cement concrete can be got.
