Graphene oxide modified immature soil-based material and nano-modification method thereof
The invention discloses a graphene oxide modified immature soil-based material and a nano-modification method thereof. The nano-modification method comprises the following steps: taking 0.03-0.12 partby mass of graphene oxide powder or turbid liquid; adding 0.1-0.4 part of a polycarboxylate superplasticizer and 35 parts of water into the graphene oxide powder or turbid liquid to be stirred and subjected to ultrasonic dispersion, and obtaining a graphene oxide mixed solution; taking 60-100 parts of immature soil, 5-15 parts of cement, 5-20 parts of fly ash and 5-15 parts of slag in the solid raw materials, and uniformly stirring; and mixing the graphene oxide mixed solution with a solid raw material so that the graphene oxide mixed solution and the solid raw material are fully and uniformly mixed to obtain the graphene oxide modified immature soil-based composite material. According to the graphene oxide modified immature soil-based material, the hydration reaction of cement and a mineral admixture can be excited through graphene oxide, so that the hydration process can be regulated and controlled, the excellent mechanical property and durability of the immature soil-based materialare remarkably improved, and the shrinkage rate is reduced.
