Summary:By adding different types and amounts of flocculants into concrete, the effects of different types and amounts of flocculants on the initial flow performance, slump retention performance and compressive strength of concrete at different ages were studied. The test results show that PAM-3 has the greatest influence on the performance of concrete. When the content of PAM-3 exceeds 0.48g/15L, the compressive strength of concrete will be reduced. When the content of PAM-1 and PAM-2 is less than 0.24g/15L, it has no obvious influence on concrete performance. When PAC content is less than 1.8g/15L, it has no obvious influence on concrete performance. Increasing the amount of concrete admixture can alleviate the adverse effect of flocculant on concrete to a certain extent.
