Mineral-based cementing material and application thereof on channel slope protection
The invention belongs to the field of channel slope protection curing materials, and particularly relates to a mineral-based cementing material and application thereof to channel slope protection. According to alkali excitation activity, a crystallization principle formed by natural minerals and a chemical process principle formed by natural colloids, the cementing material has efficient and rapid cementing and curing effects on various natural soils, and mineral powder and steel slag are adopted as materials, so that the cost can be reduced, the fluidity of tailing slurry is improved, and the hydration heat of cement in a master batch is reduced; the later strength is enhanced, the internal structure of the slope protection material is improved, and the impermeability and corrosion resistance are improved. Under the standard curing condition, the mineral-based cementing material and the on-site soil are mixed according to the mass ratio of 1: 1, the unconfined compressive strength within 3 days can reach 10-12 MPa, and the unconfined compressive strength within 28 days can reach 24-26 MPa. The thought of a conventional cement-based cementing material is broken, and the traditional cementing material is led to develop towards a natural mineral material which is free of pollution and low in cost.
本发明属于航道护坡固化材料领域，具体涉及一种矿物基类胶凝材料及其在航道护坡上的应用。依据碱性激发活性和天然矿物形成的结晶原理与天然胶体形成的化学过程原理，该胶凝材料对各种天然土具有高效快速胶凝固化作用，采用矿粉、钢渣作为材料，可以降低成本，改善尾矿浆液流动度，降低母料中水泥水化热，增强后期强度、改善护坡材料的内部结构，提高抗渗和抗腐蚀能力。打标准养护条件下，矿物基类胶凝材料与现场土1:1质量比混合，3天无侧限抗压强度可以达到10‑12MPa，28天无侧限抗压强度可达到24‑26MPa。破了常规水泥基胶凝材料的思路，引领传统胶凝材料向无污染、成本低廉的天然矿物材料方向发展。
