Ultrahigh-strength carbon sequestration cementing material and preparation method thereof
The invention discloses an ultrahigh-strength carbon sequestration cementing material and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing a carbon sequestration cementing material, a double-hydrophilic block copolymer and water to obtain a mixture; the mixture is subjected to forming and carbonization curing, and the ultrahigh-strength carbon sequestration cementing material is obtained. The double-hydrophilic block copolymer is creatively used as a carbonization reinforcing agent of the carbon sequestration cementing material, so that the mechanical property of the carbon sequestration cementing material is greatly improved, the double-hydrophilic block copolymer can regulate and control the crystal form of a carbonized product, the double-hydrophilic block copolymer is combined with calcium ions to form hydrogel with an ionic cross-linked network, and the hydrogel is filled in pores; the calcium carbonate can be used as a template of calcium carbonate crystallization to form a carbon organic-inorganic composite structure, so that calcium carbonate grains grow in an oriented manner, the combination between the calcium carbonate crystals is improved, and the mechanical property of the material is greatly improved; the enhancement technology is simple in process and low in cost, widens the application range of the carbon sequestration cementing material, and has a good application prospect.
