Efficient internal curing material and preparation method thereof
The invention discloses an efficient internal curing material and a preparation method thereof. According to the technical scheme, the efficient internal curing material is prepared from the following raw materials in parts by weight: 15-25 parts of superfine zeolite, 5-10 parts of diatomite and 65-80 parts of hydroxyapatite microspheres. The water absorption and water release functions of the porous mineral admixtures with different particle sizes in the hydration process of the cementing material and the synergistic effect of the filling effect and the secondary hydration activity effect of the superfine mineral admixtures are fully exerted, so that the plastic shrinkage and cracking of the concrete are obviously reduced, and the long-term mechanical property and durability are obviously improved.
本发明公开了一种高效内养护材料及其制备方法，技术方案包括以下重量份数的原料：超细沸石15‑25份、硅藻土5‑10份、羟基磷灰石微球65‑80份。本本发明通过充分发挥不同粒径多孔矿物掺和料在胶凝材料水化过程的吸水与释水功能和超细矿物掺和料的填充效应与二次水化活性效应之间的协同作用，实现混凝土塑性收缩和开裂显著降低、长期力学性能和耐久性能明显改善。
