High-strength concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, and particularly discloses high-strength concrete and a preparation method thereof. The high-strength concrete is prepared from the following components in parts by weight: 200 to 300 parts of cement; 300 to 400 parts of river sand; 500 to 700 parts of broken stone; 2-4 parts of a water reducing agent; and 70-80 parts of water. The river sand refers to river sand with the particle size of 0.6-1.2 mm; and the crushed stones are crushed stones with the particle size of 10-15mm. The high-strength concrete prepared by the method disclosed by the invention has relatively high compressive strength; moreover, the high-strength concrete is prepared by using common river sand and gravel as aggregates, the raw material source is wide, the preparation process is simple, and the production cost is relatively low.
本发明涉及混凝土制备技术领域，具体公开了一种高强度混凝土及其制备方法。所述的高强度混凝土，其包含如下重量份的组分：水泥200～300份；河砂300～400份；碎石500～700份；减水剂2～4份；水70～80份。所述河砂是指粒径为0.6～1.2mm的河砂；所述的碎石是指粒径为10～15mm的碎石。本发明所述方法制备得到的高强度混凝土具有较高的抗压强度；并且，本发明所述的高强度混凝土以常用的河砂和碎石为骨料制备而成，原料来源广泛，制备工艺简单，生产成本相对较低。
