Abstract

Abstract

This paper selects 4 factors(mass of binder,proportion of fly ash(FA),proportion of Granulated blast furnace slag(SL),water to binder ratio(W /B)) and 3 levels for each factor,then an orthogonal test table(L9(34)) is used to respectively analyse the compressive strength of 10 d and 28 d.The results show that the proportion of FA is the first main factor to affect the compression strength of early age(10 d) concrete.The W /B is the second factor.But for 28 d concrete,the W /B is the first main factor and the mass of binder is the second factor.For all of the test ages,the proportion of SL has the least effect on the compressive strength.According to the analysis result and the need of engineering,it has been designed a concrete mix sufficient to meet a standard requirement and construction need.
- orthogonal design,
- railway box girders,
- strength,
- water to binder ratio
