Abstract

As a new-type material for pavement structure, porous concrete has aroused a broad attention and discussion all around the world on the preparation technology and optimization design. The choice of material ingredient and its proportion of porous concrete have been discussed and corresponding tests had been done. Porous concrete were tested compressive strength and flexural strength by adding two kind different concrete admixtures including ZS-3 and Etonish845. The results indicated gradation and particle size of aggregate and ratio of aggregate to cement are the key factors affecting porosity and compressive strength of porous concrete; concrete admixtures such as ZS-3 and Etonish845 can improve the properties of the porous concrete. Porous concrete is suitable for lighten road in strength and permeable ability. In recent years, "Sponge city construction technical guide" was released by housing construction, which aim was to build a permeable, retaining, aquiferous, purified, useful, drainage city and to make the city collect and reuse the rain like the sponge[1] . With the development of the city, city area is much bigger than old one. However impervious surface coverage rate is more 30% than construction land. Water use is growing but the water repetition rate of our country is only 20%,which is lower 30% than international average value[2].In addition, the city would be flooded with rain owe to the mistake of urban duct. What's more, the flood with pollutants in the roads would polluted the underground water. It would add the sewage treatment cost and make the social burden heavier [3].It is necessary to make a kind of concrete which is suitable for lighten roads. The concrete not only relieve the pressure on urban drainage facilities, but also solve a part of environment issues. This paper seek for mixture ratio of concrete suitable for lighten roads via doing lots of experiments. We explored the influence factors of porous concrete by adding different kinds of admixtures and changing the content of coarse aggregate. The permeable road which made by porous concrete have some functions such as porous, noise reduction, anti-skating, ooling. The road can relieve urban water shortage and heat island phenomena, conserve and protect of water resources.
