Research on Cement Pulverized Admixture of Waste Concrete Powder

Abstract:

This study was carried out to test the feasibility of a mixture of cement, waste concrete powder (WCP) for their permeability, compressive strength and flexural strength. Various samples with different mass ratios of this mixture were tested to determine their permeability, compressive strength and flexural strength. The best proportions of 10% WCP, 90% cement and 0% NaOH excitant with a value of 51.3MPa was obtained at 28d, and the flexural strength can reach 8.6MPa. Moreover, the samples containing 10% WCP , 90% cement and 1% Na₂SiO₃ excitant also showed quite good compressive strength and flexural strength with values of 45.1MPa and 8.3MPa, respectively, while the samples containing 30% WCP and 70% cement showed low compressive strength and flexural strength.
