Low-heat cement with high slag powder mixing amount and preparation method of low-heat cement
The invention belongs to the field of cement, and particularly relates to low-heat cement with high slag powder mixing amount and a preparation method of the low-heat cement. The doping amount of the slag powder in the low-heat cement disclosed by the invention reaches 55-65%. The low-heat cement with high slag powder mixing amount adopts a method of matching the medium hydration heat clinker and the slag powder, so that the hydration heat in the clinker is effectively reduced, the later strength of the cement is met, the use performance of the concrete is optimized, and the requirements of customers are met. The concrete ingredients of the cement comprise the following components in percentage by mass: 30.5 to 35.5 percent of clinker, 55.0 to 65.0 percent of slag powder, 1.0 to 5.0 percent of limestone and 3.0 to 4.0 percent of dihydrate gypsum. According to the cement prepared by the invention, the hydration heat of the cement is reduced, and the later strength of the cement is guaranteed; the physical property is superior to that of the same type of cement, so that more special construction environments and special engineering requirements can be met, the later-stage quality of the concrete can be effectively ensured, a wider market is developed, and customer requirements are met; meanwhile, the preparation method and the raw materials meet the green and environment-friendly requirements.
本发明属于水泥领域,特别涉及一种高矿渣粉掺量低热水泥及其制备方法。本发明所述低热水泥中矿渣粉掺量达55‑65%。其高矿渣粉掺量低热水泥采用中水化热熟料与矿渣粉两种配合的方法,有效降低熟料中水化热同时满足水泥后期强度,优化混凝土使用性能,满足客户需求。所述水泥具体配料的各组分以质量分数计包括以下组分:熟料:30.5‑35.5%,矿渣粉:55.0‑65.0%,石灰石:1.0‑5.0%,二水石膏:3.0‑4.0%。本发明制备得到的水泥既降低了水泥水化热,又保障了水泥后期强度;物理性能优于同类型水泥,因此能满足更多特殊施工环境、特殊工程要求,能够有效的保证混凝土后期质量,开拓更广的市场,满足客户需求;同时其制备方法与原料符合绿色环保的需求。
