Full-hole slag phase change anti-freezing concrete and preparation method thereof
The invention provides full-hole slag phase change anti-freezing concrete and a preparation method thereof. The full hole slag phase change anti-freezing concrete is prepared from the following raw materials in parts by weight: 200 to 600 parts of Portland cement, 10 to 300 parts of dolomite-based hole slag stone powder, 600 to 1500 parts of dolomite-based hole slag sand, 1 to 10 parts of nano SiO2, 1 to 50 parts of solid phase change material and 100 to 300 parts of water. The full-hole slag phase-change anti-freezing concrete has the characteristics of excellent anti-freezing and thawing performance, good mechanical properties and the like, the problem of durability of the concrete caused by high-frequency freezing and thawing is greatly improved, the anti-freezing and thawing use requirements of the concrete in severe cold areas are met, the problem of concrete cracking caused by freezing and thawing cycle of building structures in the severe cold areas is solved, and the service life of the whole-hole slag phase-change anti-freezing concrete is prolonged. And the service life of the building is greatly prolonged, and important practical application value is achieved.
本发明提供一种全洞渣相变抗冻混凝土及其制备方法。该全洞渣相变抗冻混凝土，包括以下重量份的原料：硅酸盐水泥200～600份、白云岩基洞渣石粉10～300份、白云岩基洞渣砂600～1500份、纳米SiO2 1～10份、固体相变材料1～50份和水100～300份。本发明全洞渣相变抗冻混凝土具有优异的抗冻融性能以及良好的力学性能等特点，大幅改善高频冻融所带来混凝土耐久性问题，实现了严寒地区混凝土的抗冻融使用需求，解决了严寒地区建筑结构因冻融循环而引起的混凝土开裂问题，使建筑物使用寿命大幅提高，具有重要的实际应用价值。
