High-strength anti-freezing and anti-cracking concrete and preparation process thereof
The invention discloses high-strength anti-freezing and anti-cracking concrete and a preparation process thereof. The high-strength anti-freezing and anti-cracking concrete is prepared from cement, water, fine sand, medium sand, blast furnace slag, waste concrete slag, anti-cracking fibers, mineral powder, plant fibers, plant starch and an additive, the cement, the mineral powder and the blast furnace slag are matched, the fine sand, the medium sand and the waste concrete slag are matched by fully utilizing the material characteristics of the cement, the mineral powder and the blast furnace slag to serve as a matrix, and the anti-crack fibers, the plant fibers, the plant starch and the normally required additives are matched, so that after the concrete is prepared by mixing, the internal materials are fully mixed and combined together; according to the present invention, the concrete prepared by the method has characteristics of good anti-freezing property, high strength and good applicability through the synergistic cooperation of the components so as to provide the concrete with characteristics of good anti-freezing property, high strength and good applicability, and the prepared concrete has characteristics of good anti-freezing property, good anti-freezing property, good anti-freezing property, good anti-freezing property, good anti-freezing property, good anti-freezing property, good anti-freezing property and good anti-freezing property. And a good guarantee is provided for long-term use of the concrete after construction.
本发明公开了一种高强度抗冻抗裂混凝土及其制备工艺，包括水泥、水、细砂、中砂、高炉矿渣、废旧混凝土渣、抗裂纤维、矿粉、植物纤维、植物淀粉和外加剂；该发明通过水泥和矿粉与高炉矿渣相配合，充分利用其物料特性来配合细砂、中砂和废旧混凝土渣做基质，而通过抗裂纤维、植物纤维、植物淀粉和正常所需的外加剂配合，能够在混合制成混凝土后，使其内部物料充分混合且组合在一起，让其内部质地紧密，不仅可以让混凝土具有良好的抗冻性能，并且能够通过降低混凝土的孔隙率来防止其受损，通过其各个组成成分的协同配合，使得该混凝土具有良好抗冻性能的同时，又具有高强度且适用性良好的特点，为施工后混凝土的长期使用提供了良好的保障。
