Preparation and application of concrete with waste stone foam
The invention provides preparation and application of concrete with waste stone foam. The preparation method comprises the steps that waste stone is screened and crushed, waste stone particles with the particle size being 5-15 mm serve as waste stone coarse aggregate, and waste stone particles with the particle size being 0.15-5 mm serve as waste stone fine aggregate; the screened waste rock particles with the particle size smaller than 150 micrometers, cement clinker and ardealite are dried and ground till the particle size is 45 micrometers or below, mixing is conducted to obtain a composite gel material, the waste stone coarse aggregate, the waste stone fine aggregate and the composite gel material are mixed, a water reducing agent and water are added, uniform stirring is conducted, then pouring, forming, demolding and standard curing are conducted, and the high-performance concrete is prepared. The technical problem that a large amount of solid waste is difficult to utilize is solved, environmental pollution and resource waste are avoided, the comprehensive utilization rate of the solid waste is increased, energy consumption is reduced, meanwhile, the added value of products can be increased, and good economic benefits can be generated; and a new utilization way is provided for comprehensive utilization of the waste stones.
本申请提供一种具有废石沫混凝土的制备及应用，该制备方法包括将废石筛分、破碎，粒径为5～15mm的废石颗粒作为废石粗骨料，粒径在0.15～5mm的废石颗粒作为废石细骨料；对筛出的粒径小于150μm的废石颗粒、水泥熟料和磷石膏烘干处理后，研磨至粒径在45μm以下，并进行混合得复合凝胶材料，将废石粗骨料、废石细骨料和复合凝胶材料混合，加入减水剂和水，搅拌均匀，然后进行浇筑、成型、脱模和标准养护，制备得到高性能混凝土。本申请不仅解决了大宗固体废弃物难以利用的技术难题，避免了环境污染和资源浪费，提高了固体废弃物的综合利用率，减少了能源消耗，同时还能够提高产品附加值，能产生较好的经济效益，并且为废石的综合利用提供了一条新的利用途径。
