High-strength water permeable brick prepared from industrial solid waste ferronickel slag
The invention provides a high-strength water-permeable brick prepared from industrial solid waste ferronickel slag. The high-strength water-permeable brick is prepared from the following raw material components in percentage by weight: 20-28% of Portland cement; 63-70% of ferronickel slag; 1%-3% of silica fume; 0.08%-0.12% of a water retention thickening agent, 1.8%-2.2% of a binder and 0.2%-0.4% of a water reducing agent; 0.35%-0.45% of a waterproof agent; 4.5%-6.3% of water; wherein the ferronickel slag is industrial solid waste ferronickel slag with the particle size of 1.25 mm to 4.75 mm; the mass percentage of active silicon dioxide in the silica fume is more than or equal to 95%, the specific surface area is 18000-22000m < 2 >/kg, the water demand ratio is not more than 110%, and the activity is gt after 28d; 115%; the water retention thickening agent is one or more of hydroxypropyl methyl cellulose, hydroxyethyl cellulose and hydroxymethyl cellulose, and the viscosity of the water retention thickening agent is 100 to 1000 mPa. S. The water permeable brick with high strength, high durability and high water permeable rate is prepared through a stirring process and a forming process by utilizing the characteristics of particle morphology, high strength and wear resistance of the ferronickel slag and the activity effect of the silica fume, so that the industrial waste residues are widely applied to construction projects.
