▎ 摘　　要

NOVELTY - Modifier comprises graphene oxide and carbon nanotube at weight ratio of 1-4:1-4:1-4. The graphene oxide and carbon nanotube are compounded to form a three-dimensional reinforced structure with nano-scale. USE - The modifier is useful for preparing the reinforced cement-based material (claimed). ADVANTAGE - The modifier: improves the dispersibility of the carbon nano-tube, the dispersion stability of the graphene oxide and carbon nano-tube compound reinforcing system and the strength of the silicate cement base material and has better effect than graphene oxide and carbon nano-tube with the same doping amount. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing modifier; (2) a reinforced silicate cement-based material; and (3) preparing the reinforced silicate cement-based material.
