Abstract: The present disclosure provides use of a graphene oxide/butyl acrylate/silane composite emulsion as an anti-shrinkage agent of a cement-based material. In the present disclosure, active groups on an isobutyltriethoxysilane molecule reacts with hydroxyl groups on a surface of a mortar to form a layered hydrophobic structure, thereby slowing a water loss in the mortar of the cement-based material and avoiding cracking caused by drying shrinkage. Butyl acrylate can be dehydrated to form polymer fibers with a spatial network to fill pores of a cement paste, thereby limiting the shrinkage of the mortar. Graphene oxide has a relatively large specific surface area and oxygen-containing functional groups on a surface, which can provide growth sites for hydration products, and promote the hydration products to form a regular and dense structure in the form of a template, thus ensuring a strength of the cement-based material.

Abstract: Provided is the use of a silane composite emulsion as an anti-cracking enhancer in a cement-based material. In the present disclosure, active groups on an isobutyltriethoxysilane molecule react with hydroxyl groups on a surface of a mortar to form a layered hydrophobic structure, slowing down a water loss inside the mortar of a cement-based material. The dehydration of butyl acrylate forms a network structure, which fills pores of the cement-based material, inhibits shrinkage of the cement-based material, and reduces the cracking caused by the shrinkage. Tetraethoxysilane can undergo hydrolysis at a room temperature to generate nano-silica with a large number of hydroxyl groups on a surface; and the nano-silica can undergo secondary hydration with calcium hydroxide in the cement to form a secondary hydration product C—S—H gel, thereby filling most of voids to make a structure of the cement hydration product denser, to increase a strength of the mortar.
