橡胶混凝土与普通混凝土的黏结斜剪性能
|
摘要
采取立面浇筑办法,用普通混凝土作为老混凝土,浇筑橡胶混凝土与普通混凝土的黏结试件,从不同界面剂的类型和掺入橡胶的颗粒粒径、掺入数量及改性方法等方面对黏结试件斜剪强度的影响开展研究。试验结果显示:黏结斜剪强度值与橡胶颗粒粒径大小成反比关系。橡胶混凝土与普通混凝土的黏结斜剪强度随着橡胶颗粒掺入数量的变化没有明显的变化规律,但整体上呈现出下降的趋势;在结合面涂新型环氧界面剂比未涂界面剂和涂敷水泥浆界面剂显著提高了黏结剪切强度;复合改性对橡胶混凝土和普通混凝土黏结剪切强度的影响取决于橡胶颗粒粒径的大小。
This paper presents an experimental study on the adhesive bonding properties between new rubber concrete and old ordinary concrete under slant shear, including the effects of particle size, dosage, and interfacial agent on the adhesive properties. Test results show that this adhesive strength of two bonded specimens has an inverse relationship with the diameter of rubber particles, and has insignificant correlation with rubber content, though it decreases when increasing the content. Compared with cement paste interfacial agent or no agent coating, the new epoxy interfacial agent obviously improves the adhesive strength.The effect of compound modification on the adhesive strength is related to the diameter of the rubber particles.
