Study of a Rapid Method About Mix Proportion Design of C120UHPC
The mix proportion design of Ultra-high Performance Concrete(UHPC)does not have a unified,authoritative formula to use.In order to get the proportion of C120UHPC quickly,the basic proportion was determined by EMMA MIX Analyzer,then the fluidity of non-fiber mortar and the strength test of mortar were carried out to determine the laboratory mix proportion for UHPC.At last,it was found that the strength of the non-fiber mortar specimen 40 mm×40 mm×160 mm is similar to that of the standard specimen 100 mm×100 mm×100 mm with 2%steel fiber by volume at 7 and 28 days of age,at the age of 28 days,the strength was over 130 MPa.The method is simple and practical,and can provide a new idea and new method for engineers and technicians who design and implement the mix proportion of UHPC.
