Background
With the development of socio-economic and the progress of city construction, the earth surface of modern cities is gradually covered by reinforced concrete building and impervious pavement, compared with natural soil, the modern earth surface brings a series of problems to cities, which mainly appear in the following aspects:
the impervious pavement blocks the downward seepage of rainwater, so that the supplement of the rainwater to the underground water is blocked, and the urban ground is easy to sink due to the excessive extraction of the underground water;
the air can rapidly expand to generate noise when the tire rolls over, and the noise is particularly obvious in rainy days, so that the life and work of residents are influenced;
the traditional urban road surface is of an impervious structure, rainwater is discharged through a road surface, the drainage capacity is limited, when heavy rain or heavy rain occurs, rainwater is easy to collect on the road surface and is concentrated on a motor vehicle and a bicycle lane in a large amount, large-range water accumulation on the road surface is caused, the urban air humidity is reduced through the impervious road surface, the formation of an urban heat island effect is accelerated, the impervious road surface is a 'death ground', the ecological system of the ground can be influenced, the water ecological state can not normally circulate, the balance of the urban ecological system is broken, and the normal growth of vegetation is influenced.
The pervious concrete is developed and used by countries in Europe, America, Japan and the like aiming at the defects of the road surface of the urban road, and is a material which can make rainwater flow into the ground, effectively supplement underground water, and relieve urban problems such as rapid decline of the underground water level of the city and the like.
The pervious concrete is characterized in that a thin cement layer is coated on the surface of a coarse aggregate and is mutually bonded to form a honeycomb structure with uniformly distributed pores, so that the pervious concrete has the characteristics of air permeability, water permeability and light weight, has 15-25% of pores, can enable the water permeability speed to reach 31-52L/m/h, and is far higher than the discharge rate of the most effective rainfall under the optimal drainage configuration, the density of the material is low, so that the heat storage capacity is reduced, the unique pore structure enables the lower underground temperature to be transmitted into the ground, so that the temperature of the whole paved ground is reduced, and the temperature of the pervious concrete ground is lower than that of a normal concrete ground due to the characteristics, so that the pervious concrete can be used as a ground material.
Chinese patent CN 108059476 a discloses a water permeable concrete and a preparation method thereof, cement: selecting Portland cement above 42.5 grade, or slag cement or quick-hardening cement; in order to improve the strength, a small amount of a highly active mixed material such as silica fume or the like may be incorporated. Aggregate: the grading of the aggregate is an important index for determining the strength and the water permeability of the aggregate, and in order to ensure the strength and the good water permeability, the coarse aggregate needs to adopt a single particle size fraction with smaller particle size; such as 10 to 20 mm. In addition, the self-strength, particle shape (needle and flake contents), mud content and the like of the aggregate are also required correspondingly. According to the water-permeable concrete and the preparation method thereof, the water-permeable terrace has 15% -25% of pores, so that the water permeability speed can reach 31-52L/m/h, and is far higher than the discharge rate of the most effective rainfall under the best drainage configuration.
