【 摘 要 】

The effect of Al2(SO4)3 + Li2CO3 + C6H15O3N compound early strength agent on the early mechanical properties of concrete is studied in this paper, the microanalysis was carried out by SEM scanning electron microscope. The results showed that Al2(SO4)3 + Li2CO3 + C6H15O3N composite early strength agent had very significant enhancement effect. The flexural strength of concrete reaches 7.9MPa for 8 hours, and the compressive strength is 43.06MPa, which is increased by 648% and 259% respectively, compared with those without the early strength agent.
