Early strength concrete and preparation method thereof
The invention discloses early strength concrete and a preparation method thereof, the concrete is prepared from the following raw materials in parts by weight: 310 to 330 parts of cement, 46 to 50 parts of admixture, 820 to 840 parts of fine aggregate, 1000 to 1050 parts of coarse aggregate, 4 to 7 parts of early strength component and 150 to 160 parts of water, the early strength component comprises calcium formate, calcium bromide and triisopropanolamine, the mass ratio of the calcium formate to the calcium bromide to the triisopropanolamine is 40: 40: 1, and the compressive strength and the breaking strength of the early strength concrete produced by the invention are obviously improved.
本发明公开了一种早强混凝土及其制备方法，该混凝土由水泥浆、掺和料、细骨料、粗骨料、早强组分以及水，各原料按重量份计为：水泥310‑330份、掺和料46‑50份、细骨料820‑840份、粗骨料1000‑1050份、早强组分4‑7份、水150‑160份，所述早强组分包括甲酸钙、溴化钙以及三异丙醇胺，所述甲酸钙、溴化钙、三异丙醇胺的质量比为：40:40:1，本发明生产的早强混凝土在抗压强度和抗折强度方面均有明显提升。
