Enhanced pasty admixture and preparation method thereof
The invention provides an enhanced slurry admixture. The enhanced slurry admixture is prepared from the following raw materials: filter-pressed ceramsite concrete cutting waste slurry, recycled aggregate and a dispersing and chemical enhancing component, wherein the main raw materials are filter-pressed ceramsite concrete cutting waste slurry and recycled aggregate, and the dry weight mass ratio of the ceramsite concrete cutting waste slurry to the recycled aggregate is (4-10): 1; the dispersing and chemical enhancing component is metered by an external additive, the mass of the dispersing and chemical enhancing component accounts for 0.5%-1% of the dry weight of the main raw materials, the dispersing and chemical enhancing component is a mixture of an early-strength polycarboxylate superplasticizer, triisopropanolamine and sodium thiocyanate, and the mass ratio of the early-strength polycarboxylate superplasticizer to the triisopropanolamine to the sodium thiocyanate is (8-15): (2-4): (5-15). The reinforced pasty admixture provided by the invention is small in fineness and high in activity, and has a remarkable reinforcing effect on concrete.
本发明提供一种增强型浆状掺合料，其原料包括：压滤的陶粒混凝土切割废浆、再生骨料、分散与化学增强组分；其中，主要原料为压滤的陶粒混凝土切割废浆和再生骨料，陶粒混凝土切割废浆与再生骨料的干重质量比为(4‑10):1；所述分散与化学增强组分以外加剂来计，其质量为主要原料干重的0.5％‑1％，分散与化学增强组分为早强型聚羧酸减水剂、三异丙醇胺和硫氰酸钠的混合物，其中早强型聚羧酸减水剂、三异丙醇胺和硫氰酸钠的质量比为(8‑15):(2‑4):(5‑15)。本发明提供的增强型浆状掺合料细度小，活性高，对混凝土具有显著的增强效果。
