High-strength concrete for building construction and processing technology thereof
The invention discloses high-strength concrete for building construction, and particularly relates to the technical field of concrete, the high-strength concrete comprises the following raw materials: Portland cement, fly ash, mixed aggregate, basalt fiber, modified carbon fiber, hollow glass fiber, an additive and water. The carbon fibers are elastomers before being broken, the breaking is instantly started and completed, the carbon fibers are added into the concrete, concrete pores are filled with the carbon fibers, tiny cracks caused by shrinkage can be effectively reduced, and the carbon fibers are modified by utilizing nitric acid and hydrogen peroxide under the assistance of ultrasonic waves, so that the cracking resistance is improved. According to the invention, the carbon fibers are added into the concrete, many pore structures can be formed on the surfaces of the carbon fibers, the carbon fibers are mixed with the silica sol after the surface area of the carbon fibers is increased, the silica sol coats the surfaces of the carbon fibers, and the silica sol has a good bonding effect, so that the bonding effect of the concrete can be better by the silica sol when the concrete is filled with the carbon fibers; therefore, the mechanical property of the concrete is effectively improved.
本发明公开了一种建筑施工用高强度混凝土，具体涉及混凝土技术领域，包括以下原料：硅酸盐水泥、粉煤灰、混合骨料、玄武岩纤维、改性碳纤维、空心玻璃纤维、添加剂和水。本发明碳纤维在断裂前是弹性体，断裂是瞬间开始和完成的，在混凝土中加入碳纤维，碳纤维填充到混凝土孔隙中能够有效减少收缩引起的微小裂缝，而且碳纤维利用硝酸和过氧化氢，并在超声波辅助下进行改性，能够在碳纤维表面形成较多的孔隙结构，增加碳纤维表面积后与硅溶胶进行混合，使得硅溶胶包覆在碳纤维表面，由于硅溶胶具有较好的粘接作用，所以在碳纤维填充到混凝土内部时硅溶胶能够使混凝土的粘接效果更好，从而有效提高混凝土的力学性能。
