High-strength roadbed concrete and preparation method thereof
The invention discloses high-strength roadbed concrete and a preparation method thereof. The method for preparing the high-strength roadbed concrete comprises the following steps: taking industrial solid waste thiourea filter residues (Ca(OH)2) and fly ash as cementing materials, taking graded big stones and thermal power plant slag as coarse and fine aggregates respectively, adding a certain proportion of external water, and carrying out raw material pretreatment, stirring and mixing, thereby obtaining the high-strength roadbed concrete. The product provided by the invention can replace otherroadbed stabilizing materials to be used for paving base layers and sub-base layers of cement concrete highway engineering of a second grade and below. Meanwhile, the industrial solid waste is safelyand efficiently utilized to prepare the high-strength roadbed concrete, so that on one hand, the utilization of national non-renewable resources is reduced, on the other hand, the utilization value of the industrial solid waste resources is maximized, and the pollution of the industrial solid waste to the environment is greatly reduced; and industrial waste residues are safely and efficiently utilized, high-strength roadbed concrete is obtained, and the invention has great significance in environmental protection and waste utilization.
本发明公开了一种高强路基混凝土及其制备方法。制备高强路基混凝土采用的方法是将工业固废硫脲滤渣(Ca(OH)2)、粉煤灰作为胶凝材料，将级配硕石、热电厂炉渣分别作为粗细骨料，加一定比例的外加水，经原材料预处理、搅拌混合制备而成，本发明产品可代替其它路基稳定材料用于二级及二级以下水泥混凝土公路工程基层和底基层的铺筑。同时本发明安全高效地利用工业固废制备高强路基混凝土，一方面减少了国家非可再生资源的利用，另一方面将工业固废资源利用价值最大化，大大减少了工业固废对环境的污染；安全高效利用工业废渣，获得具有高强度的路基混凝土，此发明具有环保利废的重大意义。
