一种纤维自密实混凝土及其制作方法
摘要：
本发明公开了一种纤维自密实混凝土，其原料及单位体积用量包括：水泥330-334kg/m3，矿物掺和料140-144kg/m3，粗骨料835-842.8kg/m3，细骨料790-797.6kg/m3，玄武岩纤维0-8.4kg/m3，外加剂34.3-44.8kg/m3，水178-182kg/m3。玄武岩纤维为短切玄武岩纤维或预处理短切玄武岩纤维。本发明公开了上述纤维自密实混凝土的制作方法，将玄武岩纤维、细骨料和粗骨料混合均匀，接着依次加入水和外加剂搅拌均匀，然后加入水泥和矿物掺和料搅拌。本发明所得混凝土不仅质轻，而且增强混凝土各部分的强度和韧性，同时也能保持玄武岩纤维的耐热和耐腐蚀性能。
摘要（英）：

The invention discloses fiber self-compacting concrete, which comprises the following raw materials by unit volume: 330-334 kg/m<3> of cement, 140-144 kg/m<3> of a mineral admixture, 835-842.8 kg/m<3>of coarse aggregate, 790-797.6 kg/m<3> of fine aggregate, 0-8.4 kg/m<3> of basalt fiber, 34.3-44.8 kg/m<3> of an admixture and 178-182 kg/m<3> of water, wherein the basalt fiber is chopped basalt fiber or pretreated chopped basalt fiber. The invention discloses a manufacturing method of the fiber self-compacting concrete, wherein the method comprises: uniformly mixing basalt fiber, fine aggregateand coarse aggregate, sequentially adding water and an admixture, uniformly stirring, adding cement and a mineral admixture, and stirring. According to the invention, the obtained concrete is light in weight, the strength and the toughness of all parts of the concrete are enhanced, and the heat resistance and the corrosion resistance of basalt fibers can be kept.
