Moisturizing self-curing concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses moisturizing self-curing concrete, which is prepared from the following raw materials in parts by weight: 200 to 250 parts of cement, 130 to 150 parts of diatom ooze, 600 to 680 parts of gravel, 400 to 440 parts of quartz sand, 80 to 100 parts of shell powder, 60 to 80 parts of bentonite, 25 to 30 parts of moisturizing agents and 110 to 150 parts of water. The highest compressive strength of the moisturizing self-curing concrete in 7 days and 28 days is 76.9 MPa and 80.2 MPa respectively, the lowest slump, cracking area and dry shrinkage are 69 mm, 634.1 mm < 2 >/m < 2 > and 0.016% respectively, and the moisturizing self-curing effect of the concrete is improved while the high compressive strength is kept.
本申请涉及混凝土技术领域，具体公开了一种保湿自养护混凝土，其包括如下重量份的原料：水泥200‑250份、硅藻泥130‑150份、碎石600‑680份、石英砂400‑440份、贝壳粉80‑100份、膨润土60‑80份、保湿剂25‑30份、水110‑150份。本申请的保湿自养护混凝土7d和28d的抗压强度最高分别为76.9MPa和80.2MPa，且坍落度、开裂面积和干缩率最低分别为69mm、634.1 mm2/m2和0.016%，在保持较高抗压强度的同时，提高了混凝土的保湿自养护效果。
