Description
Technical field
The present invention relates to technical field of concrete, particularly relate to a kind of high intensity pervious concrete and preparation method thereof.
Background technology
In Process of Urbanization Construction, the earth's surface of modern city is progressively covered by the hardening of the material water-proof material such as building and concrete
Lid, defines " the artificial desert " on ecology, means of transportation easily, lays smooth road and bringing to the trip of people
The most simultaneously, these fluid-tight road surfaces bring negative effect greatly also to the ecological environment in city.First, tradition
Ground pavement it is emphasised that the sturdy and durable and usability on ground, but the impermeability of this kind of paving by valuable from
So precipitation completely with lower soil and subsoil water blocking-up, precipitation major part enters rivers,lakes and seas etc. by sewerage system pipe network
In earth surface water source, the excess extraction of urban groundwater, causes Urban Underground water level more and more lower, defines geologically in addition
" funnel type " level of ground water, causes ground to decline, and coastal area also results in inwelling, and this has just had a strong impact on having of rainwater
Effect utilize, during the most waterproof ground pavement rainfall rainwater be first pass through ground drainage grade or ground show that ditch enters lower water
Road, rainwater could enter Urban Underground drainage system through the rainwash of relatively long distance before entering sewer.This process
The rainwater making initial relative clean dissolves in substantial amounts of urban surface pollutant, the secondary pollution produced in this runoff process, logical
Cross sewerage system and enter peripheral ground natural water, increased the weight of the pollution level of natural water, have impact on urban surface and plant
The growth of thing, destroys urban surface ecological balance；Secondly the ground pavement of this surface compact is unfavorable for alleviating making an uproar of city
Sound pollutes, the noise mainly produced from road traffic；The rainy day due to can not draining in time, cause surface gathered water, make rain
It driving produces the phenomenons such as " drift is sliding ", " splashing ", " Night Glare ", travels to pedestrian's trip and vehicle and makes troubles；Additionally this
Kind is fluid-tight mats formation and the common effect of surrounding cities building, can increase city " tropical island effect "；Also have due to its color
Gloomy, lack anger, modern city is also referred to as " heat island of Lycoperdon polymorphum Vitt ".
Need now one can meet pavement performance, simultaneously again can be comfortable for people's class formation with natural environment coordinated growth
The paving material of living environment.Permeable concrete is a kind of environmental environment-friendly concrete.It is a kind of through special work
What skill was made has the concrete of continuous gap.Its existing certain intensity, has again certain ventilative water permeability, can be fine
Alleviate the waterproof impact that environment is caused of mating formation.
Pervious concrete is also known as celluar concrete, non-fine concrete, permeable terrace.It is by aggregate, cement and water mixing
A kind of porous light concrete become, it does not contains fine aggregate, coarse aggregate Surface coating a thin layer cement mortar mutually bonds and shape
Become the equally distributed alveolate texture in hole, therefore there is ventilative, permeable and lightweight feature.
Pervious concrete by American-European, Japan and other countries for the defect on the road surface of former urban road, the one of application
Rainwater can be allowed to flow into underground, effective recharge of groundwater, alleviate some urban environments of the level of ground water drastically decline etc. in city
Problem.And the harm of the environmental pollutions such as ground oil compounds can be effectively eliminated；Meanwhile, it is protection subsoil water, dimension
Protect ecological balance, the excellent pavement material of urban heat land effect can be alleviated；It is conducive to the benign development of environment for human survival
And in the work such as urban rainwater management and water prevention and cure of pollution, there is special significance.
Pervious concrete system has series colour formula, and the intention of matching design, for varying environment and individual demand
Decorated style carry out laying construction.This is that tradition is mated formation and the irrealizable special pavement material of general water-permeable brick.
Pervious concrete begins to research and application in the U.S. from the 1970s and 1980s in last century, and many countries are all in a large number
Promote, as the road reformation of 90% to be become pervious concrete by Germany's expection in a short time, change and destroy urban ecology in the past
Ground is laid, and makes pervious concrete pavement depend on to obtain social benefit widely.
Nano material is little due to size so that it is has special performance in terms of structure, physics and chemical property, is current
The focus of materialogy area research, is described as " century the most promising material " by scientists.The invention provides high intensity saturating
Water coagulation soil, has the physical and mechanical properties of excellence.
