This study focused on exploring the application effect of a new type of admixture in concrete,the synergist,and evaluated the effect of the synergist on the construction performance and strength of concrete through concrete tests with different dosages of synergist.Studies have shown that synergists can significantly improve the cohesion and pumpability of concrete,while reducing the amount of cement by about 10-15%,effectively reducing production costs,and the study confirms that synergists can bring economic and social benefits to the concrete industry while ensuring the strength and working performance of concrete.
