The orthogonal experiment research on premixed wet mortar

experiment Abstract. As a new kind of environmental protection building material, premixed wet mortar possesses a wide application prospect. The technical difficulty is to maintain the workability of premixed wet mortar as long as construction required setting time by choosing suitable raw materials and mix proportion. In this paper, the effect of water-binder ratio, sand type, the type and content of admixture were investigated using orthogonal experiment in respect of consistency, setting time, water-retention rate, compressive strength, etc. The range value and the most significant factor were obtained based on the range analysis, and the mix proportion is optimized.
