【摘要】 研究了P/Mg比,骨料砂／粉比,液／粉比(L／P)对石英磷酸盐包埋料流动性和抗压强度的影响,结果表明,当P/Mg比为1．5,粉／液比为0．44时材料的综合性能最好。更多还原

【Abstract】 the effects of P/Mg ratio, as well as coarse sand/fine sand ratio of aggregates, water/powder ratio, on the strength and the fluidity of Phosphate-bonded silica investment were investigated. The results indicate that when P/Mg ratio is 1.5 and water/power ratio is 0.44,the material has the best performance.更多还原
