Environment-friendly Portland cement and preparation method thereof
The invention discloses environment-friendly Portland cement and a preparation method thereof. The preparation method of the environment-friendly Portland cement comprises the following steps: carrying out copolymerization grafting on ethyl orthosilicate, isobutyltriethoxysilane and graphene oxide, and then adsorbing sodium p-dimethylamino azobenzene sulfonate on the graphene oxide to prepare a reinforcing agent; portland cement clinker, limestone, bentonite, fly ash, slag, calcined clay, gypsum, titanium dioxide and a reinforcing agent are selected as raw materials, and the environment-friendly Portland cement is prepared through grinding and calcining processes. Compared with the prior art, the environment-friendly Portland cement prepared by the invention has the characteristics of water conservation and environment friendliness, and slurry sand prepared from the cement is good in flowability and high in strength.
本发明公开了一种环保型硅酸盐水泥及其制备方法。本发明环保型硅酸盐水泥的制备方法包括以下步骤：采用正硅酸乙酯、异丁基三乙氧基硅烷与氧化石墨烯共聚接枝，然后将对二甲氨基偶氮苯磺酸钠吸附在氧化石墨烯上，制备成增强剂；选用硅酸盐水泥熟料、石灰石、膨润土、粉煤灰、矿渣、煅烧粘土、石膏、二氧化钛和增强剂作为原料，经过研磨和煅烧工艺制备成环保型硅酸盐水泥。与现有技术相比，本发明制备的环保型硅酸盐水泥具有节约用水、环境友好的特点，采用该水泥制备的浆砂流动性好、强度高。
