摘要
Abstract
Taking river sand, calcium carbonate , gypsum, barite as similar materials, an experi-ment scheme called three controlling factors with five variable levels, which consisted of the weight ratio of aggregates to cementing material, calcium carbonate to gypsum and barite powder to aggre-gates, was set up by applying orthogonal design method.Through laboratory mechanics experiment, mechanics indexes of different schemes such as density, compressive strength, and elastic modulus were obtained and analyzed, thus deduced relation equation between similar material proportion and mechanics index.The results show that the barite content has a key effect on density of similar ma-terial.The weight ratio of aggregates to cementing material was the primary controlling factor of compressive strength.The elastic modulus mechanics index was mostly affected by the weight ratio of aggregates to cementing material, then the barite content, and it was least affected by the weight ratio of calcium carbonate to gypsum.The regression relation equation between similar material pro-portion and mechanics index was obtained by using MATLAB, which could be used to determine the ratio of similar material model test.关键词
