AI Technical Summary
Technical Problem
Existing permeable concrete is prone to cracking under sulfate corrosion, resulting in a reduction in overall strength.
Method used
By using crack-resistant components such as glutinous rice paste, rubber particles, and modified fibers, the bonding effect of glutinous rice paste and the buffering effect of rubber particles reduce the expansion force of calcium sulfate or ettringite crystals, and the modified fibers reduce the contact time of sulfates, thereby improving the corrosion resistance of concrete.
Benefits of technology
It effectively reduces the corrosion of concrete by sulfates and improves the overall strength and crack resistance of permeable concrete.

Abstract
This application relates to the field of concrete production, specifically disclosing a corrosion-resistant permeable concrete and its preparation method. The corrosion-resistant permeable concrete comprises the following components by weight: 1300-1600 parts coarse aggregate, 300-400 parts cement, 30-40 parts lime, 5-7 parts water-reducing agent, and 120-170 parts water. The corrosion-resistant permeable concrete also includes a crack-resistant component, which comprises 30-40 parts by weight of glutinous rice paste. The permeable concrete of this application has the advantage of reducing sulfate corrosion of concrete, making the overall strength of the concrete less prone to decline; furthermore, the preparation method of this application has the advantage of simple operation.
