Nano-clay modified fiber cement mortar and preparation method thereof
The invention relates to nano-clay modified fiber cement mortar and a preparation method thereof and belongs to the field of concrete preparation. The nano-clay modified fiber cement mortar is prepared by a gel material, nano-clay particles, PVA fiber, a plasticizer, a water reducing agent, quartz sand and water, wherein the gel material consists of, by mass, pulverized fuel ash 60%-70% and the balance cement, the nano-clay particles accounts for 1% of the weight of the gel material, the plasticizer accounts for 0.1%-0.2% of the weight of the gel material, the water reducing agent accounts for 0.3%-0.5% of the weight of the gel material, the quartz sand accounts for 30%-35% of the weight of the gel material, the water-gel ratio ranges from 0.25 to 0.35, and the mixing amount of the PVA fiber accounts for 1%-2% of the total volume of the cement mortar. The nano-clay modified fiber cement mortar fully utilizes the unique effects of the nano-clay particles and the PVA fiber, and the chloride penetration resistance performance and mechanical property of a cement base body can be remarkably improved.
