Through tests on the workability of concrete, setting time and compressive strength of different anti-segregation raw materials, B1 was selected as the anti-segregation raw material.Then, a series of anti- segregation agents were compounded by blending B1 with cement and mineral powder in certain proportions respectively. The effects of the anti-segregation agents on the workability, setting time and compressive strength of concrete were studied.The results show that after adding anti-segregation agents J2, J3 and J4 to the segregated concrete, compared with the blank concrete, the cohesion of the concrete is improved, the workability is enhanced, the effect on the setting time is minimal, and the 28-day compressive strength of the concrete can be increased.
