Anti-abrasion concrete and application thereof
The invention relates to abrasion-resistant concrete and application thereof, and belongs to the field of concrete for low-temperature construction. The abrasion-resistant concrete is prepared from the following components in parts by weight: 890 to 900 parts of Portland cement, 157 to 222 parts of silica fume, 804 to 934 parts of fine sand, 140 to 142 parts of steel fiber, 34 to 57 parts of a Glenium 3030NS high-efficiency water reducing agent and 193 to 234 parts of water. By controlling the selection and specific proportion of the raw materials of the concrete, the compressive strength and the anti-abrasion strength of the concrete after low-temperature curing at 10 DEG C or below are high, the compressive strength is larger than 75 MPa, the anti-abrasion strength is larger than 32 h.m < 2 >/kg, and the concrete is convenient for abrasion prevention and repair of release structures at low temperature.
本发明涉及一种抗冲磨混凝土及其应用，属于低温施工用混凝土领域。该抗冲磨混凝土由以下重量份的组分组成：890～900份硅酸盐水泥、157～222份硅灰、804～934份细砂、140～142份钢纤维、34～57份Glenium 3030NS高效减水剂、193～234份水。本发明通过控制混凝土各原料的选择和特定配比，使混凝土在10℃以下低温养护后的抗压强度和抗冲磨强度较高，抗压强度＞75MPa，抗冲磨强度＞32h·m2/kg，该混凝土便于低温下的泄水建筑物的冲磨预防和修复。
