Causes of concrete segregation The reasons for concrete segregation may be improper pouring and vibrating, the maximum particle size of aggregate is too large, the proportion of coarse aggregate is too high, the content of cementitious material and fine aggregate is too low, and the density of coarse aggregate is higher than that of fine aggregate. Or the ready-mixed concrete is too dry or too thi...
