摘要:
为了研究活性粉末混凝土(RPC)的基本力学性能,在查阅各国相关文献的基础上,进行了一系列RPC力学性能试验和试验数据分析,得到了RPC的抗压强度、劈裂强度、弹性模量、泊松比、钢筋与RPC的黏结强度等数据,比较了钢筋在RPC和普通混凝土(NC)中的黏结性能,分析了RPC的应力-应变关系。结果表明:RPC的棱柱体应力-应变关系曲线接近于直线,为脆性材料; 其力学性能总体上优于普通混凝土; 泊松比可取为0.2,劈裂强度、弹性模量及轴心抗拉强度等可采用普通混凝土的经验公式进行计算。
Abstract:
To study the basic mechanical property of reactive powder concrete(RPC), through referring pertinent literature, a series of mechanical property tests and data analyses, authors gave the statistics of compressive strength, cleavage strength, modulus of elasticity, Poisson's ratio of RPC and steel bars' bonding strength in RPC, compared the bonding properties of steel bars in RPC and normal concrete(NC), then analyzed the destructive shape and stress and strain relation of RPC. The results show that stress and strain relation of RPC is a line, so it is a kind of brittle material. Its mechanical property is better than normal concrete. Poisson's ratio of RPC can use 0.2. Cleavage strength, modulus of elasticity and tensile strength of RPC can be calculated by emprical formula of NC.
