Composite admixture for concrete and preparation method thereof
The invention discloses a composite admixture for concrete. The composite admixture is prepared from the following raw materials in parts by weight: 12-21 parts of silica, 11-16 parts of black rock, 24-43 parts of blast furnace slag, 15-31 parts of quarry stone powder, 15-31 parts of ceramic factory tiles, 9-21 parts of fly ash, 0.5-2 part of a grinding aid and 0.1-3 part of ammonium persulfate. The invention also provides a preparation method of the composite admixture for the concrete. The composite admixture for the concrete can reach the national standard secondary standard, and meanwhile,the strength of the blended concrete is effectively improved.
本发明公开了一种混凝土用复合掺合料，由以下重量组分的原料制备得到：硅石12‑21份、黑岩石11‑16份、高炉渣24‑43份、采石场石粉15‑31份、陶瓷厂瓷片15‑31份、粉煤灰9‑21份、助磨剂0.5‑2份、过硫酸铵0.1‑3份。本发明还提供了上述混凝土用复合掺合料的制备方法。该混凝土用复合掺合料能够达到国标二级标准，同时有效提高了掺混后混凝土的强度。
