Full-hole-slag high-performance concrete and preparation method thereof
The invention discloses a full-hole-slag high-performance concrete and a preparation method thereof. The full-hole-slag high-performance concrete is prepared from the following raw materials by weight: 720-770 parts of ordinary Portland cement, 300-330 parts of fly ash, 2000-2200 parts of hole slag coarse aggregate, 1460-1760 parts of hole slag fine aggregate, 35-55 parts of a polycarboxylate superplasticizer and 320-370 parts of water, wherein the hole slag coarse aggregate is hole slag with a particle size of 5-25mm, and the particle size of the hole slag fine aggregate is 0-5mm, all the rawmaterials are sequentially mixed and stirred to prepare the full-hole-slag high-performance concrete. The hole slag is used as coarse aggregate and fine aggregate of the concrete, the prepared full-hole-slag high-performance concrete has excellent working performance and mechanical performance, consumption of natural gravel resources is reduced, the engineering construction efficiency is improved, and the engineering cost is reduced.
本发明公开了一种全洞渣高性能混凝土及制备方法其原料以重量份计包括：普通硅酸盐水泥720‑770份、粉煤灰300‑330份、洞渣粗骨料2000‑2200份、洞渣细骨料1460‑1760份、聚羧酸减水剂35‑55份和水320‑370份，其中，洞渣粗骨料为粒径5‑25mm的洞渣，洞渣细骨料为粒径0‑5mm，将各原料依次混合搅拌制备得到全洞渣高性能混凝土。本发明利用洞渣作为混凝土的粗骨料和细骨料，制备出的全洞渣高性能混凝土具有优异的工作性能和力学性能，既减少了天然砂石资源的消耗，提高了工程建设效率，降低了工程成本。
