【摘要】 硅酸盐混凝土是建筑工程领域广泛运用的建筑材料,但是随着建筑施工的要求的迚一步提升,硅酸盐混凝土的自身缺陷日益明显,这导致其应用范围推广受限。采用添加SiO₂粉体对硅酸盐混凝土凝结时间性、安固性和抗折性的实验研究,以期在试验后硅酸盐水泥净浆、水泥胶砂、混凝土,以及浆体流动性,各项力学性都能有所提升。更多还原

【Abstract】 Cement concrete is a building material widely used in the field of construction engineering. However, with the further increase of the requirements for building construction, the self-defect of cement concrete has become increasingly obvious, which has limited its application and promotion. In this experiment, SiO₂ powders were used to modify the cement concrete, in order to improve the performance of portland cement paste, cement mortar and concrete, such as setting time, mechanical performance, slurry fluidity and so on.更多还原
