Lime-free autoclaved aerated concrete and preparation method thereof
The invention relates to the technical field of concrete and preparation thereof, in particular to lime-free autoclaved aerated concrete and a preparation method thereof, and aims to solve the problems that cement and lime need to be used for production and preparation of existing autoclaved aerated concrete at present, the cost is high, a large amount of cement and lime are exploited, the ecological environment is damaged, and the production cost is low. In order to solve the problem that the existing lime-free autoclaved aerated concrete has high strength and high strength and seriously affects the safety of public facilities, the invention provides the following scheme that the preparation method of the lime-free autoclaved aerated concrete comprises the following steps of S1, raw material preparation, S2, mixing, S3, concrete preparation and S4, application, and aims to achieve the purposes that calcined lime is not used in the concrete preparation process, the raw materials are wide in source, low in cost and excellent in performance, and the lime-free autoclaved aerated concrete is prepared. The raw materials comprise fly ash, carbide slag and desulfurized gypsum, a small amount of cement is supplemented, a large amount of solid waste is consumed, and benefits are brought to the nation and the people.
本发明涉及混凝土及其制备技术领域，尤其涉及一种无石灰蒸压加气混凝土及其制备方法，针对当前现有的蒸压加气混凝土的生产制备需要使用水泥、石灰，成本较高，且水泥、石灰的大量开采，不仅破坏了生态环境，还严重影响了公共设施的安全的问题，现提出如下方案，其中无石灰蒸压加气混凝土的制备方法包括以下步骤：S1：原料准备,S2:混合，S3：制备混凝土,S4：应用，本发明的目的是通过在制备混凝土的过程中不使用煅烧石灰，原料来源广泛，成本低廉，性能优良，同时原材料采用粉煤灰、电石渣、脱硫石膏，辅以少量水泥，大量消耗固体废弃物，利国利民。
