Influence of Concrete Synergist on Performance of Stone Chip Concrete

The concrete synergist can reduce the amount of cementitious material, keep the performance of the concrete not reducing or even improving. By adjusting the ratio, effect of concrete synergist on the properties of stone chip concrete was studied, results showed that in reducing the dosage of cement, concrete synergist can also effectively improve the working performance of concrete. The early strength of concrete adding synergist is inferior as that of the base, after the later the strength will increase slightly. Adding synergist, shrinkage of concrete is larger, the contraction slows after later period. By adding concrete synergist, concrete electric flux declines slightly, which is beneficial to anti permeability of concrete. Concrete synergist can optimize the microstructure of concrete and increase the density of concrete. The application of the concrete synergist is feasible and can be used to improve the efficiency of the materials.
