High-performance rubber concrete material and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to a preparation method of a high-performance rubber concrete material, which comprises the following steps: (1) carrying out ultrasonic treatment on rubber powder, rubber particles, water and tetraethoxysilane, adding a silane coupling agent, continuously carrying out ultrasonic treatment for 30 minutes, drying and sieving to obtain modified rubber powder and modified rubber particles; (2) uniformly mixing calcium fluosilicate, aluminum oxide and magnesium oxide, calcining at high temperature, adding blast furnace slag and silicon powder, and grinding and activating under pressure to obtain a reinforcing agent; and (3) uniformly mixing cement, fly ash and gypsum, adding water, stirring to obtain slurry, adding the modified rubber powder, the modified rubber particles and the reinforcing agent, then adding the functional additive, the short glass fiber and the medium sand, and uniformly mixing to obtain the rubber concrete. The compressive strength of the prepared rubber concrete is 42 MPa or above, the tensile strength ranges from 3.0 MPa to 4.0 MPa, the breaking strength ranges from 5.0 MPa to 6.0 MPa, and application requirements are met.
本发明属于建筑材料技术领域，具体涉及一种高性能橡胶混凝土材料的制备方法，包括下列步骤：（1）将橡胶粉和橡胶颗粒与水、正硅酸乙酯超声，再加入硅烷偶联剂，继续超声30min，干燥、过筛，得到改性橡胶粉和改性橡胶颗粒；（2）将氟硅酸钙、氧化铝、氧化镁混匀，高温煅烧后，再加入高炉矿渣和硅粉，带压研磨活化，得到增强剂；（3）取水泥、粉煤灰、石膏混合均匀，加水搅拌，得到浆料，加入改性橡胶粉、改性橡胶颗粒和增强剂，再加入功能助剂、短玻纤和中砂，混匀得到橡胶混凝土。本发明制得橡胶混凝土抗压强度在42MPa以上，抗拉强度3.0MPa～4.0MPa，抗折强度5.0MPa～6.0MPa，满足应用要求。
