Energy-saving thermal-insulation building material prepared based on phosphogypsum and preparation method of energy-saving thermal-insulation building material
The invention provides an energy-saving thermal-insulation building material prepared based on phosphogypsum and a preparation method of the energy-saving thermal-insulation building material. According to the invention, calcium oxide in blast furnace slag powder is combined with the phosphogypsum to form calcium hydroxide, and silicon oxide and aluminum oxide in waste glass powder are combined for a slow reaction to form hydrated silicate or hydrated calcium aluminate, so the structure of concrete is made denser and the strength of the concrete is enhanced; and meanwhile, silicon carbide is combined with the mixed ceramsite, so the overall strength of the concrete is enhanced, the mass of the concrete is reduced, and the fireproof and sound insulation effects of the concrete are improved.
本发明的一种基于磷石膏制备的节能保温建材及其制备方法，通过利用高炉矿渣粉中的氧化钙与磷石膏结合，形成氢氧化钙，并结合废玻璃粉中的氧化硅和氧化铝进行缓慢反应形成水合硅酸盐或水合铝酸钙，以使混凝土的结构更致密并增强混凝土的强度，与此同时，利用碳化硅与混合陶粒结合，以增强其整体的强度、降低其质量，并提高其防火隔音效果。
