Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of water conservation brick.
Background technology
China is a hydropenia big country, the occupancy volume of domestic water resource per capita is only the 1/4 of world average level, developing rapidly and expanding along with modern city, hardened ground amasss and accounts for more than the 65% of urban size, it is meant that the most little space is for artificial greening and other purposes.Modern city ecological environment exist problem mainly have following some:
First, " tropical island effect " is the common fault of modern city, owing to surface sealing makes the earth the most inadequate with air heat exchange, steam group is collected at overhead, city and can not circulate dissipations, and urban life is produced by this vicious cycle and ecological environment causes and threatens greatly and destruction；
Second, waterlogging takes place frequently, and a part of reason the most proper causes due to urban ground hardening, and greenery area is less in addition, and flowing water cannot all quickly be dredged by underground piping so that urban transportation and productive life paralyse condition；
3rd, road surface airborne dust, little granule dust and flying dust fill the air in urban environment, and the nitrogen oxides during oil-fired vehicle produces tail gas in addition pollutes, and this wire is polluted and accumulated over a long period, the ecological environment of city and surrounding area will be caused serious threat, cause the frequent severe overweight of PM2.5；
4th, Application of Urban Rain Water inferior capabilities, reason is that municipal administration hardening thing water retention property in ground is poor, or is flowed away through underground by major part rainwater, it is impossible to rationally recycled by rainwater；
5th, there is serious negative influence to natural, humanistic environment around in the vehicles and the other noise produced of road；
6th, the dunghill that life produces, such as chewing gum, advertisement sticker, food residues etc., it is attached to road surface and is difficult to thoroughly remove；
7th, summer, surface temperature was the highest under burning sun tans by the sun, and a part of reason is that the brick heat absorption capacity on earth's surface is poor, it is impossible to adsorbs and retains heat；
8th, traditional brick typically uses natural clay sintering to form or make with conventional cement and sand, not only can not recycle waste material, more can not turn waste into wealth, also can destroy natural environment.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of water-holding capacity is good, has noise reduction and absorbs waste gas decomposition pollutant function, the ecological water conservation brick of surface easy to clean, is primarily applicable for the field such as municipal ground, underground engineering.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that a kind of ecological water conservation brick, it is characterised in that: use following dispensing, by weight, composite Portland cement 0.8-1.2 part, husky 3-5 part, construction waste 1-2 part together with agricultural crop straw, preparation process is as follows:
1), by the crops stalk crushing after dehydration, being pulverized by construction waste, the construction waste after then pulverizing is mixed homogeneously with agricultural crop straw；
2), composite Portland cement, sand and construction waste are placed in the mixture of agricultural crop straw together with and mix homogeneously；
3), the water of total weight of the mixture 5-15% is added, while add waterside stirring, until stirring；
4), the concrete mould compaction molding that will stir, the dynamics of suppressing is 1-2T；
5), at room temperature placing, after molding 24h water brick body, number of times is every day 2-3 time, continues 5-7 days, is allowed to structural strength and increases to complete maintenance.
Further, the surface photocatalyst coating application in brick body has one layer of photocatalyst coating.Photocatalyst is under the light of specific wavelength (388nm) irradiates, the photosynthetic a series of energy conversion process of similar plants Determination of Chlorophyll can be produced, luminous energy is converted into chemical energy and gives the oxidability that photocatalyst surface is the strongest, the various organic compound of oxidable decomposition and mineralising part inorganic matter, and there is antibacterial effect.
Under light illumination, photocatalyst can absorb the luminous energy being equivalent to below band-gap energy so that it is surface occurs excitation to produce electronics (e-) and hole (h+).These electronics and hole have the strongest reduction and oxidability, can react with the oxygen that water or appearance are deposited, and produce hydroxyl free radical (OH) and super cloudy oxonium ion (O).The energy of oxidation of these holes and hydroxyl free radical is more than 120kcal/mol, has the strongest oxidability, almost can be cut off by the chemical bond of all composition organic molecules and decompose.Therefore various harmful chemicals, odorant can be decomposed or harmless treatment, reach to purify air, the effect of anti-soil deodorization.Photocatalyst is mainly made up of nano level titanium dioxide.
Further, described sand hill includes drift-sand and rough sand, and the mean diameter drift-sand less than 1 millimeter is brick fabric；Mean diameter is that the rough sand of 1-3 millimeter and drift-sand are as brick body material.
Further, at least one during described construction waste includes brick waste material, concrete waste material, Wooden composite floor waste material and ceramic products waste material；Construction waste is 1:(0.3-3 with the ratio of agricultural crop straw).
Further, the porosity of this water conservation brick is 25-35%, and volume water absorption rate is 20-30%.Although conventional hollow brick and honeycomb brick also can meet or exceed this water absorption rate, but it is by reduce brick laying structure intensity as cost.
The present invention is of new generation unburned by using the combinations such as desert dust storm, construction waste, agricultural crop straw to make, the green ecological urban construction material of energy-saving and emission-reduction；There is Rain water returning and collecting function, it is achieved recycling of water resource, be Resources for construction economizing type and a particularly important ring in environment excellent type city；And with photo-catalytic coating as the permanent cleaning agent of brick body, thus have water conservation, purification, freeze proof take precautions against drought, anti-skidding, the function of noise reduction.
Topmost advantage is, first, and utilizing inexhaustible desert wind sand, construction waste and agricultural crop straw is main raw material(s), not only cost reduces 30-50%, and meet the green idea of Ecological Civilization Construction, improve urban ecological environment, and contribute to desert improvement and treatment of urban garbage；Second, excellent water retention property can realize low cost, utilize rainwater resource on a large scale, reduces the loss that city is caused due to Poor construction quality of terrace-bank, slows down urban waterlogging, it is achieved " rain not hydrops, avenge non-slip "；3rd, structural strength is high, and physical arrangement has the effect of noise reduction, antidetonation, slows down city " tropical island effect ", utilizes water-retaining property, absorbs the thermal pollution that urban is caused；4th, brick surface light catalyst coating makes it have purification air, the function of dust out.
