▎ 摘  要

NOVELTY - An admixture for high anti-permeable marine concrete, prepared by (1) mixing and stirring the aqueous solution of silane coupling agent with the ethanol suspension of fly ash, filtering, washing, and drying to obtain silane-modified fly ash; (2) introducing silane-modified fly ash to the water dispersion of graphene oxide and mixing and stirring, filtering, washing, and drying to obtain graphene oxide/silane-modified fly ash composite material, In which admixture comprises 10-15 wt.% silane coupling agent, 70-85 wt.% fly ash, and 5-10 wt.% graphene oxide. USE - Admixtures for high impermeability marine engineering concrete used as a heterogeneous porous material for building material. Uses include e.g.roofing materials, flooring materials, and roofing tiles. ADVANTAGE - The admixture: provides the marine engineering concrete with high impermeability and can improve the density of the base body, improve the mechanical property, and improve the durability of the concrete; and reduces the quality problem of trigger quality of fly ash on the market, thus realizing efficient application of the fly ash in cement-based material, with high economic benefit and environment-friendly benefit. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of blending material for high anti-seepage marine engineering concrete.
