Preparation method of modified rubber particles and application thereof, frost-resistant water-permeable concrete and application thereof, frost-resistant water-permeable brick and preparation method thereof
The invention provides a preparation method of modified rubber particles and an application thereof, anti-freezing pervious concrete and an application thereof as well as an anti-freezing pervious brick and a preparation method thereof, which belong to the technical field of pervious building materials. The preparation method comprises the following steps: mixing rubber particles with a surface treating agent, and carrying out surface coating treatment to obtain rubber particles with surfaces coated with the surface treating agent; wherein the surface treating agent comprises the following components in parts by weight: 15-35 parts of water glass, 2-6 parts of silicon phosphate, 50-75 parts of silica powder, 0.1-1 part of urea and 0.1-2 parts of hydroxypropyl methyl cellulose; and carryingout a curing reaction on the rubber particles coated with the surface treating agent at 40-60 DEG C for 1-3 hours to obtain the modified rubber particles. When the obtained modified rubber particlesare used for preparing the frost-resistant water-permeable concrete, the modified rubber particles are high in binding force with other components of the concrete, and the prepared frost-resistant water permeable brick is good in water permeability, high in strength and excellent in frost resistance.
