Concrete prepared from glassy-state coal cinder and preparation method thereof
The invention provides concrete prepared from glassy-state coal cinder and a preparation method of the concrete. The concrete is prepared from the glassy-state coal cinder, gravel aggregate, cement and water according to the weight ratio of (30-40): (40-50): (8-10): (8-10). The glassy-state coal cinder is slag formed in the pressurized gasification process of coal, and the pressurized gasification temperature is above 1450 DEG C. According to the invention, the glassy-state coal cinder is treated and then used as a concrete raw material, can be used as fine sand aggregate and can also bear part of functions of cement, so that the use amount of a cementing material is reduced, and the cost of the concrete is reduced on the basis of ensuring the quality of the concrete.
本发明提供了一种利用玻璃态煤渣制备的混凝土及其制备方法，该混凝土包括玻璃态煤渣、砂石骨料、水泥和水，四者的重量比为30‑40：40‑50：8‑10：8‑10；其中玻璃态煤渣是煤在加压气化过程中形成的炉渣；加压气化温度在1450℃以上。本发明将通过玻璃态煤渣进行处理后作为混凝土原料，其不仅可以作为细砂骨料，还能承担一部分水泥的功能，减少胶凝材料的用量，在确保混凝土质量的基础上降低混凝土成本。
