Abstract:
The reasons of concrete’ s crack form ing and the com ponen t of Shrinkage Reduc ing Adm ix ture SRA w ere ana lyzed in th is pape r. The m echan ism of restra in ing conc rete cracks by SRA w as studied de tailedly. The effect o f SRA was validated in accordance w ith the exper iment da ta and m icrocosm ic data. The resu lt show ed proper SRA cou ld improve the shrinkage situations o f concrete. Them echanicsw ere tha t the union of agg rega te and harden cem ent w as im proved and expansion com ponen t com pensated the shrinkage o f concrete.
