Carborundum mixing machine-made sand C160UHPMC and preparation method thereof
The invention discloses emery mixing machine-made sand C160 UHPMC and a preparation method thereof. The UHPMC comprises the following components according to a matching ratio design: 850kg/m < 3 > of cement; 195.5 kg/m < 3 > of silica fume; 167.28 kg/m < 3 > of water; 467.5 kg/m < 3 > of carborundum; 467.5 kg/m < 3 > of machine-made sand; 331.5 kg/m < 3 > of quartz powder; 148.75 kg/m < 3 > of steel fibers; 60 kg/m < 3 > of a water reducing agent; and 1.5 kg/m < 3 > of a defoaming agent. The machine-made sand which is wide in source, low in price, economical and environment-friendly and can be obtained locally is used for replacing quartz sand which is high in price and pollutes the environment, the problems that the quartz sand serving as aggregate is serious in pollution, high in price, difficult in quality control and the like in the production process are solved, consumption of natural materials is reduced, and carbon emission is reduced; waste carborundum generated in the fields of abrasive blasting and the like is recycled for secondary utilization and is doped into the machine-made sand ultra-high performance concrete taking the machine-made sand as the aggregate, so that the defects of insufficient mechanical property, poor working performance and the like of pure machine-made sand UHPC are overcome; the green ultra-high performance concrete which is economical, environment-friendly, excellent in performance and low in price is prepared by changing the aggregate type.
本发明公开了一种金刚砂混合机制砂C160UHPMC及其制备方法，其UHPMC配合比设计与组成成份包括：水泥：850kg/m3；硅灰195.5kg/m3；水167.28kg/m3；金刚砂467.5kg/m3；机制砂467.5kg/m3；石英粉331.5kg/m3；钢纤维148.75kg/m3；减水剂60kg/m3；消泡剂1.5kg/m3。利用来源广泛、价格低廉、经济环保、可就地取材的机制砂取代了价格昂贵、污染环境的石英砂，解决石英砂作为骨料在生产过程中污染严重、价格偏高、质量难以把控等问题，减少了天然材料的消耗，减少了碳排放；回收喷磨等领域产生的废料金刚砂二次利用，掺入到机制砂为骨料的机制砂超高性能混凝土中，改善了纯机制砂UHPC力学性能不足和工作性能不佳等缺点；通过改变骨料类型制备了一种经济环保、性能优越、价格低廉的绿色超高性能混凝土。
