Who has steel fiber concrete mix design?
Determination of steel fiber content:The incorporation rate of selected fibers was P=1.5%,T0= (78.67*P) kg=78.67*1.5=118kg;
1, the design basis and reference"Than" design rules of JGJ552000 ordinary concrete (J64-2000)The "technical specification for construction of highway bridges and culverts" JTJ0412000Technical specifications for second volumes of the domestic highway bidding document model (1)
Defined water consumption:W=215kg (water control in general 180-220kg), with UNF-2A type superplasticizer by blending construction, cement admixture was 1%, the water reducing rate of 10%, but considering the steel fiber concrete workability is poor, and the construction is easy to agglomerate, so in the trial without considering its water reducing to observe the effect of slump and performance in the process of trial mix in construction.
