| Abstract: | According to the requirements of emergency and repair engineering,the application of ultra early strong concrete is researched.Ordinary portland cement P·O42.5 is selected,the multiple compound admixture is added,and ultra early strong concrete is made.Under the normal temperature condition,2 d can reach 70% fcu,k(design strength standard value).From the practice results indicate that this ultra early strong concrete will ensure the engineering construction quality,and improve the benefits. |
