Continuous-particle-size graded rubber powder concrete and preparation method thereof
The invention discloses continuous particle size graded rubber powder concrete and a preparation method thereof, and the continuous particle size graded rubber powder concrete is characterized in that rubber powder in a continuous particle size interval is adopted to replace a corresponding particle size range in fine aggregate gradation, and the existing gradation of fine aggregate is kept unchanged. The composite raw materials comprise ordinary Portland cement, river sand, rubber aggregate, a NaOH solution, gravel and water. The invention aims to solve the problem that the gradation completeness of fine aggregate containing rubber powder cannot be maintained before and after the rubber aggregate is replaced. The working performance of the graded rubber concrete prepared by the method is obviously improved, the mechanical property is obviously improved, the toughness is strong, and the durability is better. According to the method, continuity and completeness of grading of fine aggregate containing rubber powder are maintained, and the grading rubber powder matching ratio meeting engineering practice and the preparation method of the grading rubber powder are obtained. And new kinetic energy is provided for solving the problems of difficult treatment of waste tires and shortage of natural aggregates.
本发明公开了一种连续粒径的级配橡胶粉混凝土及其制备方法，所述连续粒径级配橡胶混凝土是指采用连续粒径区间的橡胶粉取代细骨料级配中相应的粒径范围，维持细骨料现有级配不变。组成原材料包括：普通硅酸盐水泥、河砂、橡胶集料、NaOH溶液、碎石、水。本发明旨在解决橡胶集料取代前后无法维持含橡胶粉的细骨料的级配完整的问题。该方法制备的级配橡胶混凝土工作性能得到了显著提升，力学性能改善较为明显，韧性强，耐久性更好。该方法通过维持含橡胶粉的细骨料级配的连续与完整，得到了满足工程实践使用的级配橡胶粉配合比及其制备方法。将为解决废旧轮胎处理困难和天然骨料短缺提供新动能。
