High-strength subfissure-resistant concrete for rail transit and preparation process of high-strength subfissure-resistant concrete
The invention discloses high-strength subfissure-resistant concrete for rail transit and a preparation process of the high-strength subfissure-resistant concrete. The high-strength subfissure-resistant concrete comprises the following components in parts by weight: 130-150 parts of water, 150-200 parts of cement, 300-400 parts of sand, 600-700 parts of pebbles, 30-50 parts of fly ash, 50-80 parts of a modified fiber mixture, 50-70 parts of perlite, 30-40 parts of glass powder, 10-20 parts of bentonite and 10-15 parts of silicon dioxide. Through arrangement of the fly ash, the modified fiber mixture, the perlite, the glass powder, the bentonite, the silicon dioxide and the like, the strength of the concrete can be improved through the modified fiber mixture, and the wear resistance of the concrete can be improved through arrangement of the perlite and the glass powder; and the concrete can have good strength and crack resistance.
本发明公开了一种轨道交通用高强度抗隐裂型混凝土及其制备工艺，包括以下重量份组分：水130‑150份，水泥150‑200份，沙子300‑400份，石子600‑700份，粉煤灰30‑50份，改性纤维混合物50‑80份，珍珠岩50‑70份，玻璃粉30‑40份，膨润土10‑20份，二氧化硅10‑15份。本发明通过设置的粉煤灰，改性纤维混合物，珍珠岩，玻璃粉，膨润土，二氧化硅等，能够通过改性纤维混合物增加混凝土的强度，通过设置的珍珠岩，玻璃粉能够增加混凝土的耐磨性能，配合膨润土的使用，能够使的混凝土具有良好的强度以及抗裂性能。
