Description
Technical field
The present invention relates to technical field of concrete more particularly to a kind of High-strength permeable fiber concretes.
Background technology
In Process of Urbanization Construction, the earth's surface of modern city is gradually covered by the hardening of the material water-proof materials such as building and concrete
Lid, forms " the artificial desert " on ecology, easily means of transportation, is laid with smooth road and is brought in the trip to people
While greatly convenience, great negative effect is also brought in these fluid-tight road surfaces to the ecological environment in city.First, traditional
Ground pavement it is emphasised that ground sturdy and durable and usability, but the impermeability of such paving by it is valuable from
For right precipitation completely with lower soil and underground water blocking, precipitation is most of to be discharged into rivers,lakes and seas etc. by sewerage system pipe network
In earth surface water source, the excessive of urban groundwater extracts in addition, causes Urban Underground water level lower and lower, forms geologically
" funnel type " level of ground water causes ground and declines, and coastal area also results in inwelling, this has just seriously affected having for rainwater
Effect utilize, while when waterproof ground pavement rainfall rainwater be first pass through ground drainage grade or ground show that ditch is discharged into Xia Shui
Road, the rainwash that rainwater will be Jing Guo relatively long distance before entering sewer could enter Urban Underground drainage system.The process
The rainwater of initial relative clean is set to dissolve in a large amount of urban surface pollutant, the secondary pollution generated in this runoff process is led to
It crosses sewerage system and enters peripheral ground natural water, aggravated the pollution level of natural water, affect urban surface plant
The growth of object destroys the urban surface ecological balance；Secondly the ground pavement of this surface compact is unfavorable for alleviating making an uproar for city
Sound pollutes, the noise mainly generated from road traffic；In the rainy day due to that cannot drain in time, surface gathered water is caused, rain is made
Its driving generates phenomena such as " drift is slided ", " splashing ", " Night Glare ", makes troubles to pedestrian's trip and vehicle traveling；In addition this
It is kind fluid-tight to mat formation and surrounding cities building collective effect, city " tropical island effect " can be increased；Also due to its color
It is gloomy, lack angry, modern city and is also referred to as " heat island of grey ".
Need now it is a kind of can meet pavement performance, while again can be comfortable for mankind's construction 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 by special work
Concrete with continuous gap made of skill.Its existing certain intensity, and there is certain ventilative water permeability, it can be fine
The waterproof influence of mating formation caused by environment of alleviation.
High-strength permeable fiber concrete is also known as celluar concrete, non-fine concrete, permeable terrace.Be by aggregate, cement and
A kind of porous light concrete made of water mixing, it is free of fine aggregate, mutual by coarse aggregate surface cladding a thin layer cement mortar
It bonds and forms the equally distributed honeycomb structure in hole, therefore have the characteristics that ventilative, permeable and light-weight.
High-strength permeable fiber concrete is directed to the defect on the road surface of former urban road by American-European, Japan and other countries, and exploitation makes
A kind of that rainwater can be allowed to flow into underground, effective recharge of groundwater alleviates some that the level of ground water in city drastically declines etc.
Urban Environmental Problem.And the harm of the environmental pollutions such as the oil compounds on ground can be effectively eliminated；Meanwhile being protecting field
Lower water, maintaining ecological balance, the excellent pavement material that urban heat land effect can be alleviated；It is conducive to the good of environment for human survival
On sexual development and the work such as urban rainwater management and water prevention and cure of pollution, there is special significance.
High-strength permeable fiber concrete system possesses serial colour formula, the intention of matching design, for varying environment and
The decorated style of individual demand carries out laying construction.This is that tradition is mated formation and the irrealizable special material of mating formation of general water-permeable brick
Material.
High-strength permeable fiber concrete begins to study and apply in the U.S. from the 1970s and 1980s in last century, many countries
All in large-scale popularization, such as German expection will change in a short time by 90% road reformation at High-strength permeable fiber concrete
It goes to the ground for destroying urban ecology to be laid with, high-strength fiber pervious concrete road pavement face is made to depend on to obtain extensive social benefit.
Nano material makes it have special performance in terms of structure, physics and chemical property, is current since size is small
The hot spot of materialogy area research is described as " century most promising material " by scientists.The present invention provides high-intensity fibers
Pervious concrete has excellent physical mechanical property.
