Permeable concrete using recycled aggregate and porous concrete pavement using the same method

摘要

The present invention relates to a kind of pervious concrete compositions using recycled aggregate permeable concrete road surface and to use the method for the system. It is designed to provide using recycled aggregate pervious concrete match ratio, and there is intensity and durability, be used as clinker micro mist made of permeable concrete topping construction refuse regenerated aggregate, the method that concrete road surface of breathing freely uses the system. Pervious concrete pavement method forms the compression strength 4. that pervious concrete pavement layer is respectively provided with 1 or larger infiltration coefficient, 18 MPa or bigger5 MP, flexural strength is by including: that a kind of generation step of the water permeable concrete adhesive for preparing 100 parts by weight has and cement clinker micro mist, mixed weight ratio 1:0.5-1, be mixed with 200-400 parts by weight has 5.0-10.0 millimeter of circulation aggregation classification and product mix, 0.3-0.The compound of 6 parts by weight, and have the ratio of mud (W/B) 25-30% by the way that mixing water is added; First forming step forms low pervious concrete layer, by distributing and hardening pervious concrete composition; Reinforcing mat installation step installs pervious concrete layer under reinforcing mat; And the second step forms top pervious concrete layer, is mounted thereon by distributing and hardening the lower pervious concrete layer of pervious concrete composition with reinforcing network. ;The 2015 of copyright KIPO submissions
