Method for preparing ecological concrete by synergistically utilizing coal chemical industry waste residues and waste water
The invention discloses a method for preparing ecological concrete by synergistically utilizing coal chemical industry waste residues and wastewater. The method comprises the following steps: preparing a cementing material by using low-carbon coal gasification residues generated in a coal chemical industry process as a main cementing material and a small amount of excitant as an auxiliary material, sintering high-carbon coal gasification residues to prepare lightweight aggregate with light weight and high strength, adopting coal chemical industry high salinity wastewater as mixing water, proportioning according to a certain ratio to prepare the ecological concrete, and curing by using different curing systems to treat waste with waste so as to achieve the purposes of harmless treatment and resource utilization of coal chemical industry waste.
本发明公开了一种协同利用煤化工废渣、废水制备生态混凝土的方法，该方法利用煤化工过程产生低碳煤气化渣作为主要胶凝材料，辅以少量的激发剂制备胶凝材料，用高碳煤气化渣烧结制备轻质高强度的轻质骨料，以煤化工高盐废水作为拌合水，按照一定的比例进行配比制备生态混凝土，采用不同的养护制度进行养护，从而实现以废制废，达到对煤化工废弃物无害化处理和资源化利用的目的。
