Embodiment 1
[0026] (1) Dissolve 5 parts of boron nitride nanosheets and 0.2 part of hyperbranched polyethyleneimine in 5 parts of deionized water, microwave treatment and stirring at 60 ° C, cool to room temperature after 4 hours in a nitrogen atmosphere, and then wash with ethanol Washing, centrifugal filtration, and freeze-drying to obtain modified boron nitride nanosheets, which are regarded as component A;
[0027] (2) 40 parts of superfine fly ash, 10 parts of metakaolin, 3 parts of steel slag, 5 parts of carbide slag, and 2 parts of phosphogypsum were mixed with water at a water-solid ratio of 0.35, and were regarded as component B;
[0028] (3) Put component A and component B in a homogenizer, mix and stir to make slurry, and prepare boron nitride nanosheet modified fly ash geopolymer composite bonding material.
[0029] The performance indicators of each parameter are as follows, all of which meet the requirements of the "GB-T31289-2014 Marine Portland Cement" standard:
