Whole-hole slag aggregate ultra-high performance concrete and preparation method thereof
The invention discloses whole-hole slag aggregate ultra-high performance concrete and a preparation method thereof. The whole-hole slag aggregate ultra-high performance concrete comprises the following raw materials: 680-720 parts of ordinary Portland cement, 270-320 parts of ultrafine fly ash, 100-130 parts of silica fume, 950-980 parts of whole-hole slag machine-made sand, 230-250 parts of steelfiber, 56-64 parts of a polycarboxylate superplasticizer and 180-200 parts of water. According to the whole-hole slag aggregate ultra-high performance concrete and the preparation method thereof of the invention, the whole-hole slag machine-made sand is used as the fine aggregate, so that the ultra-high performance concrete with excellent mechanical properties can be prepared, hole slag is fullyutilized, and the engineering cost is reduced.
本发明公开了一种全洞渣骨料超高性能混凝土及制备方法，其原料包括普通硅酸盐水泥680‑720份、超细粉煤灰270‑320份、硅灰100‑130份、全洞渣机制砂950‑980份、钢纤维230‑250份、聚羧酸减水剂56‑64份、水180‑200份。本发明原料采用全洞渣机制砂作为细集料，可以制备出力学性能较为优异的超高性能混凝土，使得洞渣得到充分利用，降低了工程成本。
