Modified composite fiber reinforced alkali-reducing cement-based material system and preparation method thereof
The invention discloses a modified composite fiber reinforced alkali-reducing cement-based material system and a preparation method thereof, and the system is prepared by mixing the following raw materials in percentage by weight: 45%-75% of a cement binding material, 0.1%-0.3% of modified composite fibers, 0.3%-0.5% of an efficient drag reducer and 25%-55% of an alkali-reducing protective agent, the modified composite fibers comprise modified basalt fibers and modified glass fibers, and the modified basalt fibers and the modified glass fibers are formed by modifying fiber surface coatings through nano SiO2/epoxy compounding. According to the prepared cement-based material system, the alkaline environment of the cement-based material and the alkali resistance of fibers doped in the cement-based material can be improved to a large extent, and the effect of long-term performance stability of the fiber-reinforced cement-based material is achieved.
