基于水化机理的聚合物改性再生混凝土性能研究

Research on Properties of Polymer-modified Recycled Concrete Based on Hydration Mechanism

制作了四种不同类型的聚合物改性再生骨料混凝土,并结合对比试样分别进行了抗压强度、劈裂抗拉强度性能试验及X射线衍射物相分析。结果显示,聚合物的掺入对再生混凝土抗压强度存在负面影响,对再生混土劈裂抗拉强度存在增强作用,对再生混凝土的水化进程存在一定的促进作用。

In this paper,four different types of polymer-modified recycled aggregate concrete were produced,and the compressive strength,splitting tensile strength performance tests and X-ray diffraction phase analysis were carried out in combination with the comparative samples.The results showed that the polymer The addition of the compound has a negative effect on the compressive strength of recycled concrete,enhances the splitting tensile strength of recycled concrete,and has a certain promotion effect on the hydration process of recycled concrete.
