Super-retarding concrete and preparation method thereof
The invention belongs to the technical field of concrete materials, and particularly discloses super-retarding concrete and a preparation method thereof. The super-retarding concrete provided by the invention is mainly prepared from the following concrete raw materials in parts by weight: 700 to 800 parts of cement, 1400 to 1600 parts of coarse aggregate, 500 to 600 parts of fine aggregate, 240 to 280 parts of water, 20 to 36 parts of modified retarder, 12 to 30 parts of water reducing agent, 10 to 14 parts of defoaming agent and 90 to 110 parts of reinforcing agent. According to the invention, the modified retarder is added to cooperate with the reinforcing agent to act together, so that the retarding time of the concrete is prolonged on the premise of not influencing the compressive strength of the concrete.
本申请属于混凝土材料的技术领域，具体公开了一种超缓凝混凝土及其制备方法。本申请的一种超缓凝混凝土，主要包括以下重量份的混凝土原料制得：水泥700‑800份、粗骨料1400‑1600份、细骨料500‑600份、水240‑280份、改性缓凝剂20‑36份、减水剂12‑30份、消泡剂10‑14份、增强剂90‑110份。本申请通过加入改性缓凝剂配合增强剂共同作用，从而在不影响混凝土抗压强度的前提下延长混凝土的缓凝时间。
