Ecological new material sulphoaluminate cement board and preparation method thereof
The invention relates to an ecological new material sulphoaluminate cement board and a preparation method thereof, the ecological new material sulphoaluminate cement board comprises dry powder, water and an additive, the use amount of the water is 50% of the total amount of the dry powder, the use amount of the additive is 13% o of the total amount of the dry powder, the dry powder comprises the following components in percentage by mass: 50% of semi-hydrated gypsum, 15% of fly ash, 15% of quick lime and 15% of Portland cement, 2.5% of kaolin and 2.5% of bauxite. And premixing, blending, grouting, forming and curing to obtain the novel ecological material sulphoaluminate cement plate. A large number of solid waste materials are utilized, the micro-expansion performance of the semi-hydrated gypsum is fully utilized, and shrinkage cracking of a traditional cement product is reduced. Through technological formula innovation and matching of a modified semi-hydrated gypsum crystallization process, the characteristics of high strength, toughening, water resistance, air permeability and no moisture absorption are achieved. Compared with a traditional cement product, the forming production period is shortened, the production efficiency is improved, no high-temperature and high-energy-consumption consumed solid waste is recycled in the production process for preparing environment-friendly building materials, and value-added, efficient, environment-friendly and energy-saving effects are achieved.
本发明涉及生态新材料硫铝酸盐水泥板材及其制备方法，包括干粉，水和外加剂，所述水的用量为干粉总量的50％，所述外加剂的用量为干粉总量的13‰，所述干粉，按质量百分比计，包括：半水石膏50％、粉煤灰15％、生石灰15％、硅酸盐水泥15％，高岭土2.5％、铝矾土2.5％。经预混、混配、注浆、成型、养护得到生态新材料硫铝酸盐水泥板材。采用大量利用固废材料，充分利用半水石膏的微膨胀性能，减少传统水泥制品的收缩开裂。通过工艺配方创新、配比改性半水石膏结晶工艺，达到高强，增韧、防水、透气不吸潮的特性。相比传统水泥制品的成型生产周期缩短，提高生产效率生产过程无高温高能耗的消耗固废再生利用制备环保建材，增值高效，环保节能。
