C120 steel fiber reinforced concrete and manufacturing method thereof
The invention relates to the technical field of concrete, in particular to C120 steel fiber concrete and a manufacturing method thereof. The C120 steel fiber concrete is prepared from the following raw materials: 630-680 kg/m < 3 > of cement, 60-80 kg/m < 3 > of silicon powder B, 650-750 kg/m < 3 > of river sand, 150-250 kg/m < 3 > of 5-10 broken stone B, 750-850 kg/m < 3 > of 10-20 broken stone B, 120-140 kg/m < 3 > of water, 13-18 kg/m < 3 > of water reducing agent and 80-110 kg/m < 3 > of steel fiber. According to the C120 steel fiber reinforced concrete, high-strength concrete with good workability and 28d strength reaching 144MPa is prepared by selecting raw materials and adopting a water curing system, the steel fiber is added, so that the concrete strength assurance rate is obviously improved, the breaking strength and the elastic modulus are obviously improved, the durability is enhanced, the total water consumption of per square meter of concrete is not less than 140kg, and the workability of the concrete is ensured, wherein the crushed stone crushing value is required to be below 6% so as to ensure the strength.
本发明涉及混凝土技术领域，具体的说是一种C120钢纤维混凝土及其制造方法，该C120钢纤维混凝土，其原料如下：水泥为630‑680kg/m3、硅粉B为60‑80kg/m3、河砂为650‑750kg/m3、5‑10碎石B为150‑250、10‑20碎石B为750‑850kg/m3、水为120‑140kg/m3、减水剂为13‑18kg/m3和钢纤维为80‑110kg/m3。本发明C120钢纤维混凝土通过对原材料的选择，采用水养护制度，配制出工作性较好、28d强度达144MPa的高强混凝土，钢纤维的加入，对混凝土强度保证率有明显提高效果，抗折强度及弹性模量显著提高，并增强耐久性，单方混凝土总用水量不能低于140kg，以保证混凝土的工作性，碎石压碎值要求在6％以下以保证强度。
