High-strength concrete and preparation process thereof
The invention relates to the technical field of building road construction materials, in particular to high-strength concrete and a preparation process thereof. The high-strength concrete is prepared from the following raw materials in parts by weight: 320 to 370 parts of cement, 110 to 150 parts of mineral powder, 20 to 40 parts of fly ash, 640 to 680 parts of gravel, 1000 to 1100 parts of gravel, 10 to 15 parts of water reducing agent, 120 to 150 parts of water, 160 to 180 parts of epoxy resin glue and 50 to 70 parts of modified polypropylene fiber, and the modified polypropylene fiber is obtained by recycling and reproducing waste masks. The high-strength concrete disclosed by the invention has relatively excellent compressive strength and cracking resistance.
本申请涉及建筑道路施工材料的技术领域，更具体地说，它涉及一种高强度混凝土及其制备工艺。一种高强度混凝土，包括以下重量份的原料：320‑370份水泥、110‑150份矿粉、20‑40份粉煤灰、640‑680份砂石、1000‑1100份碎石、10‑15份减水剂、120‑150份水、160‑180份环氧树脂胶、50‑70份改性聚丙烯纤维，所述改性聚丙烯纤维由废弃口罩回收再生产而得。本申请的高强度混凝土具有较为优良的抗压强度以及抗开裂性能。
