Super wear-resistant ground concrete and preparation method thereof
The invention discloses super wear-resistant ground concrete. The super wear-resistant ground concrete comprises fine aggregate, coarse aggregate, a cementing material, water, rubber powder, wear-resistant fibers and a precipitation agent. Clean fine aggregate and coarse aggregate are selected for floor concrete, the water content of the concrete is determined and converted into water consumption, and on the basis of an existing concrete floor technology, adjustment, verification and addition of part of wear-resistant fibers, rubber powder and a precipitation agent are carried out through a large number of tests, so that the overall wear resistance and compressive strength of the concrete are changed, and the service life of the concrete is prolonged. The compactness, the tensile and shear resistance and the overall wear resistance can be obviously improved, the service life is prolonged, the compressive strength can be integrally improved by 25%, and in the construction process, through the technical means of additionally arranging corner anti-vibration pads and additionally arranging elastic meshes in key areas, the risk that the overall service life is shortened due to cracks in the corners and the key areas of the ground and the road surface is reduced; construction procedures are simple, the construction period is short, and construction quality is easy to control.
本发明公开了一种超耐磨地面混凝土，该地面混凝土的组成成分包括细骨料、粗骨料、胶凝材料、水、胶粉、耐磨纤维和降水剂。本发明地面混凝土选用洁净的细骨料、粗骨料，确定其含水率，并将其含水量折算到用水量中，在现有混凝土地面技术基础上，通过大量试验进行调整、验证，增加部分耐磨纤维、胶粉、降水剂，以此来改变混凝土整体耐磨性和抗压强度，可增强其密实度、抗拉抗剪能力，整体耐磨性明显提升，延长使用寿命，抗压强度可以整体提高25％，施工过程中通过加设边角防震垫、重点区域增加弹性网片的技术手段，降低地面路面的边角及重点区域发生裂缝导致整体寿命下降的风险，施工工序简洁，施工工期短，施工质量易于控制。
