纳米水泥混凝土力学特性研究

纳米SiO2是一种新兴的材料,用途非常广泛。水泥混凝土路面存在刚性过大、抗弯拉强度不足的问题。通过在普通水泥混凝土中掺加不同量的SiO2纳米材料,测试纳米水泥混凝土的抗压强度和抗弯拉强度。研究表明:纳米SiO2的掺加能改善水泥混凝土的抗压强度和抗弯拉性能,纳米水泥混凝土抗弯拉强度的改善优于抗压强度。

Mechanical Property of Nanometer Cement Concrete

Nanometer SiO2 is a new material which is used widely. Cement concrete pavement has such problems as excessive rigidity and insufficient flexural strength. The compressive strength and flexural strength of nanometer-cement concrete are tested by adding different amount of nanometer SiO2 materials in ordinary cement concrete. The research result shows that adding nanometer SlOE can advance the compressive strength and flexu- ral strength of cement concrete, moreover the improvement of flexural strength is more obvious than compressive strength of nanometer cement concrete.
