Early strength concrete with super retarding effect, and preparation process thereof
The invention relates to an early strength concrete with a super retarding effect, and a preparation process thereof, and relates to the technical field of concrete preparation. The early strength concrete is prepared from, by weight, 180-200 parts of ordinary Portland cement, 1180-1220 parts of coarse aggregate, 600-640 parts of fine aggregate, 240-260 parts of an active admixture, 6-10 parts ofa polycarboxylate superplasticizer, 8-12 parts of a super retarder, 4-8 parts of an early strength agent and 180-200 parts of water. Addition of the super retarder and the early strength agent prolongs the initial setting time of the concrete and improves the early strength of the concrete.
本发明涉及一种具有超缓凝效果的早强混凝土及其制备工艺，涉及混凝土制备的技术领域，其包括以下重量份计原料制成：普通硅酸盐水泥180‑200份；粗集料1180‑1220份；细集料600‑640份；活性掺合料240‑260份；聚羧酸减水剂6‑10份；超缓凝剂8‑12份；早强剂4‑8份；水180‑200份。通过加入有超缓凝剂和早强剂，使得混凝土的初凝时间得到延长，且提高了混凝土的早期强度。
