摘　　要：选用了高性能砂浆垫层方案。检验了高性能砂浆的泌水率、凝结时间、抗压和劈拉强度。用碾压混凝土层间试件直剪试验,研究高性能砂浆垫层,提高碾压混凝土层面抗剪断强度的效能。High—performance mortars are chosen as lift joint bedding of RCC. Bleeding, time of setting, compressive and splitting tensile strength of these mortars are examined. Effect of such bedding to improve the lift joint strength against shear failure of RCC is investigated on joint specimens (15 cm and 30 cm cube) .
