Abstract: According to the action mechanism of various concrete admixtures, the range of dosage is se-lected, and the two base admixtures of polycarboxylate high-performance early-type water reducer and quick-setting admixture are selected for compounding test. By changing the type and amount of the base admixture, the ratio of the initial setting time of the concrete mixture, the slump and the 1d compressive strength of the concrete, the ratio of the anti-disturbing compound admixture is optimized, and the composite admixture is analyzed. The mechanism of action to improve the anti-disturbance performance of concrete.
