High-flow-state early-strength low-shrinkage semi-flexible pavement grouting material and preparation method thereof
The invention provides a high-flow-state early-strength low-shrinkage semi-flexible pavement grouting material and a preparation method thereof. The grouting material is prepared from the following raw materials: cement, oily polyurethane, fly ash, mineral powder, river sand, a water reducing agent, a retarder, a defoaming agent, cellulose and water. The cement is prepared from ordinary Portland cement and sulphoaluminate cement. The ordinary Portland cement, the sulphoaluminate cement and the oily polyurethane are subjected to combined action for the first time, the sulphoaluminate cement provides main early strength, the ordinary Portland cement ensures the later hydration process and ensures that the subsequent strength of the grouting material is not reduced, and meanwhile, the oily polyurethane further improves the strength and the hardness, so that the grouting material has a good application prospect. And the oily polyurethane has excellent adhesiveness, so that the tight combination between the grouting material and the asphalt mixture can be ensured, and the stability of the whole structure is improved.
本发明提供了一种高流态早强型低收缩半柔路面灌浆料及制备方法，由以下原料制成：水泥、油性聚氨酯、粉煤灰、矿粉、河砂、减水剂、缓凝剂、消泡剂、纤维素和水；水泥由普通硅酸盐水泥和硫铝酸盐水泥制成。本发明首次将普通硅酸盐水泥，硫铝酸盐水泥和油性聚氨酯三相进行共同作用，硫铝酸盐水泥提供了主要的早期强度，普通硅酸盐水泥确保了后期的水化过程，确保灌浆料后续的强度不会下降，同时油性聚氨酯进一步提高强度和硬度，使得灌浆料更加坚固耐用，且油性聚氨酯具有较优的黏附性，可以确保灌浆料与沥青混合料之间的紧密结合，提高整体结构的稳定性。
