Concrete product containing phosphogypsum fly ash cement and preparation method thereof
The invention provides a concrete product containing phosphogypsum fly ash cement and a preparation method thereof. The concrete product is prepared from the following raw materials in parts by weight: 130 to 240 parts of phosphogypsum, 125 to 215 parts of fly ash, 45 to 80 parts of silicate cement, 650 to 850 parts of sand, 950 to 1050 parts of stones and 145 to 165 parts of water. According to the concrete product, process waste resources are utilized, the cement consumption is reduced, and environmental protection is facilitated. The preparation method comprises the following steps: adding water into ardealite and part of silicate cement, performing wet grinding to obtain ardealite slurry, filtering and concentrating to obtain ardealite mud; mixing and stirring the ardealite mud, the fly ash, the rest silicate cement, the sand, the stones and the water, pressing or pouring to form a concrete product; and finally, performing product maintenance treatment. According to the preparation method, calcination is not needed, the concrete product is produced through direct wet grinding, the concrete strength is improved, and the setting time is shortened.
本发明提供一种含磷石膏粉煤灰水泥的混凝土制品及其制备方法，按照重量份计所述混凝土制品的原料包括：磷石膏130‑240份、粉煤灰125‑215份、硅酸盐类水泥45‑80份、砂子650‑850份、石子950‑1050份和水145‑165份。本发明的混凝土制品利用了工艺废弃物资源并降低了水泥用量，有利于环境保护。所述制备方法包括以下步骤：将磷石膏与部分硅酸盐类水泥加水湿磨得到磷石膏浆，过滤浓缩后得到磷石膏泥；所述磷石膏泥与粉煤灰、剩余硅酸盐类水泥、砂子、石子和水混合搅拌，压制或浇筑成混凝土制品，最后进行制品养护处理。所述制备方法无需煅烧，直接湿磨生产混凝土制品，提高了混凝土强度，缩短其凝结时间。
