Cement mortar and preparation method thereof
The invention discloses cement mortar and a preparation method thereof.The method comprises the following steps that S1, graphene oxide is put into water for wave dispersion to prepare a dispersion liquid; S2, under stirring, adding basalt fibers into the dispersion liquid, and continuously stirring and mixing under the condition of keeping the rotating speed unchanged, so as to obtain a mixed solution of graphene oxide and basalt fibers; S3, carrying out heat treatment on the mixed solution of the graphene oxide and the basalt fibers to obtain graphene basalt fibers; and S4, adding the graphene basalt fibers prepared in the step S3 into a stirring pot, then adding sand, cement, a polycarboxylate superplasticizer, potassium aluminosilicate, an anethene-maleic anhydride copolymer, calcium lysine phosphate and chromium trichloride hexahydrate, and performing heating and stirring to obtain the cement mortar. The compressive strength and flexural strength of a mortar test piece prepared from the cement mortar are obviously superior to those of a mortar test piece prepared in the prior art.
本发明公开了一种水泥砂浆及其制备方法，所述方法包括以下步骤：S1：将氧化石墨烯放入到水中进行波分散，得到分散液；S2：在搅拌的情况下，将玄武岩纤维加入到分散液中，保持转速不变下持续搅拌混合，得到氧化石墨烯和玄武岩纤维的混合溶液；S3：将氧化石墨烯和玄武岩纤维的混合溶液进行热处理，得到石墨烯玄武岩纤维；S4：将步骤S3制得的石墨烯玄武岩纤维加入搅拌锅中，接着加入如下物料：砂子、水泥、聚羧酸减水剂、铝硅酸钾、茴香烯‑顺丁烯二酸酐共聚物、赖氨酸磷酸钙、六水合三氯化铬后加热搅拌，制得水泥砂浆。采用本发明的水泥砂浆制得的砂浆试件的抗压强度和抗折强度明显优于现有技术制得的砂浆试件的抗压强度和抗折强度。
