Steam-curing-free precast concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses steam-curing-free precast concrete and a preparation method thereof.The steam-curing-free precast concrete is prepared from, by weight, 240-320 parts of Portland cement, 950-1050 parts of coarse aggregate, 800-850 parts of fine aggregate, 60-80 parts of admixture, 8-15 parts of compound early strength admixture, 6-8 parts of water reducing agent and 160-180 parts of water; the compound early strength admixture comprises aluminum calcium sulfate cement, calcium formate, triethanolamine, calcium aluminate and a retarder; the prepared steam-curing-free precast concrete is high in early-stage compressive strength.
本申请涉及混凝土技术领域，具体公开了一种免蒸养预制混凝土及其制备方法，所述免蒸养预制混凝土包括以下重量份的原料：硅酸盐水泥240‑320份、粗集料950‑1050份、细集料800‑850份、掺合料60‑80份、复配早强外加剂8‑15份、减水剂6‑8份和水160‑180份；所述复配早强外加剂包括硫酸铝钙水泥、甲酸钙、三乙醇胺、铝酸钙和缓凝剂；本申请制得的免蒸养预制混凝土早期抗压强度较高。
