摘要
该文在文献 [1]的基础上 ,研究了浒泊山砂中粉末对混凝土抗压强度的影响 ,分别就相同水灰比 ,相近坍落度下 ,对混凝土抗压强度 ;劈裂抗拉、抗折强度 ;抗渗性 ;抗冻性 ;收缩和钢筋握裹力等与河砂混凝土进行了对比研究 ,对山砂混凝土的微观结构进行了分析。得出含粉末 10
The paper studies effects of powder for pressure strength on the basis of literature 1, compares with pressure strength, splitting pensile, bending strength, anti-permeability, freezing resistance and bond stress of shrinkage reinforcement of river sand concrete and Hupo hill sand concrete under the condition of the same water-cement ratio and the close caving degree, analyses micro-structure of hill sand concrete. A conclusion is drawn that it is reliable for which hill sand containing 10% powder or so, can be applied in C35 and downwards concrete. [
