Internal curing material with high water absorption rate and application thereof
The invention relates to an internal curing material with high water absorption rate, which is prepared by sintering raw materials containing 65-95 parts by weight of bauxite tailings, 0-30 parts by weight of papermaking sludge particles and 0-30 parts by weight of silica fume, the invention also comprises application of the internal curing material with high water absorption rate as lightweight aggregate in mortar, the pore size distribution of the prepared internal curing material is concentrated in 100-3000nm, and the porosity can reach 39.6%. When being used for internal maintenance of mortar, the concrete shrinkage reducing agent can achieve an obvious shrinkage reducing effect only by using a small mixing amount, and meanwhile, avoids adverse effects on the strength of the mortar; according to the invention, comprehensive utilization of solid wastes is realized.
一种高吸水率的内养护材料，按重量份计算，由含有65‑95份铝矾土尾矿、0‑30份造纸污泥颗粒和0‑30份硅灰的生料烧结而成；本发明还包括所述高吸水率的内养护材料作为轻骨料在砂浆中的应用，本发明制得的内养护材料孔径分布集中在100‑3000nm，孔隙率可达39.6%。用于砂浆内养护时，仅需较少的掺量即可实现明显的减缩效果，同时避免了对砂浆强度的不利影响；本发明实现了固体废弃物的综合利用。
