Gelled sand gravel and preparation method thereof
The invention relates to the technical field of cemented sand gravel production, in particular to cemented sand gravel and a preparation method thereof. The cemented sand gravel is prepared from sandgravel material master batch, water, cement, fly ash, light particles, magnetic powder, acrylate, an additive and shrimp shell powder, the preparation method comprises the steps of pretreatment, ballmilling treatment, material preparation, cementing material preparation, cementing sand gravel base material preparation and modified cementing sand gravel preparation, the prepared cementing sand gravel has the advantages of being high in mechanical strength and high in impermeability and freezing resistance, magnetic powder is added, so that the structural density can be stably kept without being damaged, and the service life of the cementing sand gravel is prolonged. The self-healing capability is realized, the high-temperature resistance is realized, and the problem of structural deformation of the gelling sand gravel damming structure caused by high temperature can be effectively prevented by adding the gelling sand gravel of the shrimp shell powder.
本发明涉及胶凝砂砾石生产技术领域，尤其涉及一种胶凝砂砾石及其制备方法，由砂砾石材料母料、水、水泥、粉煤灰、轻质颗粒、磁粉、丙烯酸酯、外加剂、虾壳粉制成，包括前处理、球磨处理、备料、配制胶凝材料、配制胶凝砂砾石基料、配制改性胶凝砂砾石步骤，本发明制备出的胶凝砂砾石具有力学强度高、抗渗性和耐冻性高的优点，本发明添加了磁粉，使得结构密度能稳定保持不被破坏，具有自愈能力、具有耐高温性，添加了虾壳粉的胶凝砂砾石可以有效防止高温引起的胶凝砂砾石筑坝结构变形问题。
