INFLUENCE FACTORS TO THE WORKABILITY OF THERMAL INSULATION GLAZED HOLLOW BEAD CONCRETE AND MIX DESIGN USING THE ORTHOGONAL DESIGN METHOD

摘要

In this study,theoretical analysis and orthogonal test are carried out for five factors,including water consumption,sand ratio,cement dosage,gravel dosage,and admixture,which influence the working performance of thermal insulation glazed hollow bead concrete for the green building in Jincbeng of shanxi province.The effect of five factors on the compressive strength and the work performance are studied.Finally,the optimal mix proportion is to be determined based on the experimental and orthogonal analysis in order to guide the construction.
