Description
Technical field
The invention belongs to construction material preparing technical field, be specifically related to a kind of alkaline residue building waste water-permeable brick and preparation thereof
Method.
Background technology
Along with developing rapidly of China's economy and greatly developing of urbanization, greenery patches originally is by large-scale ground pavement
Replace, " the city desert " of formation considerably increases Permeable stratum area so that urban rainwater can not back to nature, its result is city
City's subsoil water reduces in a large number, has the danger that urban architecture is sunk;And meeting heavy rain when city is prominent, its rainwater on road surface cannot quickly ooze
Leakage, causes to municipal drainage facility and bears greatly and easily send out into urban waterlogging.Meanwhile, its large-area road of mating formation
Face weakens the respiratory function in city, can cause " tropical island effect ", reduces city comfort level and causes urban ecological system unbalance.
Therefore, water-permeable brick starts increasingly to be received publicity as a kind of good water permeable paving material.
On the other hand, along with industrialization, the acceleration of urbanization process, building industry is the most fast-developing, with this together be to build
Building refuse is increasing, and a large amount of building wastes not only occupy soil, and bring severe contamination to human habitat.
According to statistics, the every annual meeting of China increases building waste more than 4,000 ten thousand tons newly, and the quantity of building waste has accounted for municipal refuse total amount
More than 1/3, wherein concrete construction rubbish has accounted for again more than the 40% of building waste.This phenomenon has been obtained for the whole society
Extensive concern.Land resource is not only wasted in storing up for a long time of building waste, easily produces potential safety hazard, and be unfavorable for resource can
Sustainable development and the recycling of resource;And the heap of building waste is released and can be polluted water resource, has influence on air
Quality, and then directly influence the living environment of the mankind.
At present, it is caused to fail to be widely used in practice because water-permeable brick cost is the highest, simultaneously saturating on current market
The comprcssive strength of water brick, anti-wear performance and coefficient of permeability fail to reach active balance, therefore, how to ensure water-permeable brick performance
Reduce water-permeable brick cost great to the market application value improving water-permeable brick simultaneously.
Patent CN201510406551 discloses the preparation method of a kind of ecological ceramic water-permeable brick.Include following steps:
1) by following components and constituent content feeding, percentage by weight meter: building waste micropowder 5%-10%, building waste fine aggregate
5%-15%, building waste coarse aggregate 30%-45%, dewatered sludge 15%-20%, modified mud 15%-40%, Alumen
0.075%-0.2%, Borax 0.5%-1%;2) compression moulding method will be used after each raw material mix homogeneously to be shaped to have wedge shape
The half-blind hole test block of structure, briquetting pressure is 10-20Mpa, and after molding, natural drying 48h is dried in 80 ± 20 DEG C of environment again,
It is warming up to 300 DEG C-350 DEG C, at 300-350 DEG C after constant temperature 2.5h-3.5h, then with 3-8 DEG C/min with the speed of 2-3 DEG C/min
Speed be warming up to 1050 DEG C-1150 DEG C, sintering 3h-4h after lower the temperature.The ecological ceramic water-permeable brick production cost that the method prepares
High;Ecological ceramic water-permeable brick is formed by high-temperature calcination, while consuming building waste, increases energy consumption, aggravates greenhouse effect, right
Environment causes certain harm.
