Porous active internal curing admixture
The invention relates to a porous active internal curing admixture, which mainly comprises a natural microporous admixture component and an enhanced admixture component, and is mainly prepared from the following raw materials in parts by weight: 5-10 parts of calcined diatomite, 10-20 parts of zeolite powder, 20-40 parts of pumice powder and 30-65 parts of superfine slag powder. By fully exertingthe synergistic effect between the water absorption and release functions of porous mineral admixtures with different particle sizes in a hydration process of a cementing material and the filling effect and secondary hydration activity effect of superfine mineral admixtures, the plastic shrinkage and cracking of concrete can be obviously reduced, and the long-term mechanical properties and the durability are obviously improved.
本发明涉及一种多孔活性内养护掺和料，该掺和料主要包括天然微孔掺和料组分和增强型掺和料组分，按重量份计，主要由以下原材料组合而成：煅烧硅藻土5~10份、沸石粉10~20份、浮石粉20~40份、超细矿渣粉30~65份。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。
