Hydrated and carbonized composite hardened cementing material based on steel slag and preparation method of hydrated and carbonized composite hardened cementing material
The invention discloses a hydrated and carbonized composite hardened cementing material based on steel slag and a preparation method thereof, belongs to the technical field of building materials, and solves the problems of high consumption, high energy consumption, large CO2 emission, low carbonized and hardened body strength and narrow application range in production of natural ore from hydraulic lime/natural hydraulic lime. The hydrated and carbonized composite hardened cementing material based on steel slag comprises the following raw materials: 25-30% of cement clinker, 20-25% of pretreated carbide slag, 1.5-2.0% of industrial byproduct gypsum, 3-5% of bentonite, 0.5-1.0% of a hydrated and carbonized accelerant and the balance of steel slag. The method comprises the following steps: preparing materials, selecting iron, and grinding into powder. The hydration and carbonization composite hardening cementing material based on the steel slag has good hydration hardening performance and carbonization hardening performance, a hardened body shows good mechanical performance in water, air and CO2 atmosphere, and the application field is widened.
本发明公开了一种基于钢渣的水化碳化复合硬化性胶凝材料及制备方法，属于建筑材料技术领域，解决水硬性石灰/天然水硬性石灰生产天然矿石耗量高、能耗高、CO2排放量大以及碳化硬化体强度低、应用范围窄的问题。本发明的基于钢渣的水化碳化复合硬化性胶凝材料的原料包括25～30％水泥熟料，20～25％的预处理电石渣，1.5～2.0％的工业副产石膏，3～5％的膨润土，0.5～1.0％的水化碳化促进剂，余量为钢渣。本发明方法包括：配料，选铁，研磨成粉，即得。本发明的基于钢渣的水化碳化复合硬化性胶凝材料兼具良好的水化硬化和碳化硬化性能，硬化体在水中、空气中、CO2气氛中均表现出良好的力学性能，拓宽了应用领域。
