摘要
本文研究了不同矿物外加剂及掺量对轻集料混凝土弹性模量、收缩、徐变的影响,结果表明:通过合理地选择矿物外加剂的种类、掺量可有效地提高轻集料混凝土弹性模量,降低轻集料混凝土的收缩开裂风险,改变轻集料混凝土的徐变特性。
In this paper,it was researched of the influence of different types of mineral admixtures on the elastic modulus,shrinkage and creep.It shows that the elastic modulus of light aggregate concrete can be enhanced through rationally choosing the types and dosage of mineral admixtures.It also can be achieved to reduce the risk of crack and improve the creep of light aggregate concrete by the same way.
