Cement-free paving stone and preparation method thereof
The invention discloses a cement-free paving stone and a preparation method thereof. The cement-free paving stone is prepared from the following raw material components in parts by weight: 9 to 33 parts of salt-alkali composite exciting agent, 0.11 to 0.55 part of mixed retarder, 40 to 130 parts of water, 30 to 50 parts of mineral powder, 10 to 15 parts of powder A, 60 to 150 parts of powder B and 180 to 380 parts of aggregate, the powder A is furnace bottom slag, and the powder B is polishing slag. According to the invention, the salt-alkali composite activator, the mixed retarder, the mineral powder, the water, the powder A, the powder B and the aggregate are compounded, and the components of the raw materials are limited in the addition amount range, so that the furnace bottom slag and the polishing slag are fully utilized. Meanwhile, the paving stone product prepared from the furnace bottom slag and the polishing slag can also have high breaking strength and compressive strength under the condition that no cement is added, and the problems that in the prior art, only the polishing slag can be stacked or buried, environment pollution is caused, and resources are wasted are solved.
本发明公开了一种无水泥的地铺石及其制备方法，包括以下重量份的各原料组分：9‑33份盐碱复合激发剂、0.11‑0.55份混合缓凝剂、40‑130份水、30‑50份矿粉、10‑15份粉料A、60‑150份粉料B和180‑380份的骨料；所述粉料A为炉底渣，所述粉料B为抛光渣。本发明通过盐碱复合激发剂、混合缓凝剂、矿粉、水、粉料A、粉料B和骨料进行复配，以及将原料的组分限定在添加量范围内，使炉底渣和抛光渣得以充分利用。同时，利用炉底渣和抛光渣制备得到的地铺石产品，在没有添加水泥的情况下，也能具有较高的抗折强度和抗压强度，解决了传统只能对抛光渣做堆放或填埋处理，造成环境污染和浪费资源的问题。
