High-bending-resistance graphene oxide cement mortar and preparation method thereof
The invention discloses high-bending-resistance graphene oxide cement mortar and a preparation method thereof, and belongs to the field of new building materials. The high-bending-resistance grapheneoxide cement mortar comprises a cementing material, a mineral admixture, river sand and an additive, wherein the gel material is composed of ordinary cement, ultrafine fly ash, mineral slag and silicafume, and the mineral admixture is composed of ultrafine fly ash, mineral slag and silica fume. The mineral admixture accounts for 30% of the total weight of the cementing material, the additive is composed of graphene oxide dispersion liquid, calcined nano-clay particles and a water reducing agent, the weight of graphene oxide accounts for 0.01-0.05% of the total weight of the cementing material, and the weight of the calcined nano-clay particles accounts for 0.6-3% of the total weight of the cementing material. The high-bending-resistance graphene oxide cement mortar has the advantages of high bending strength and stable long-term performance, and is suitable for engineering parts with high bending strength requirements.
