Adaptability of PCE with cement and its test method
By detecting the chemical composition,specific surface area and particle morphology of cement,and preparing comprehensive PCE to detect the adaptability of cement with different characteristics to the PCE through the fluidity of the slurry and mortar.Through the study,it is concluded that the initial pH value of different cements in the study is between 12.3～12.6,and after the hydration begins,the fluidity loss greater with high pH value and fast growth.The content of SO3 also has a greater impact on the fluidity,and the lower content of SO3 within a certain range,the greater the fluidity loss is.And there is a certain difference in the specific surface area between the net slurry flow test and the mortar test.
