Description
Technical field
The invention belongs to building material technical fields, are related to a kind of production method of construction material, and in particular to Yi Zhongtou
The formula of water brick and its manufacturing process, more particularly, to a kind of the permeable of high intensity height infiltration prepared using big size particle materials
Brick and its manufacturing process.
Background technology
In order to realize the coordinated development of urbanization and Natural Resources Environment, urban water ecosystem is protected, rainwater calamity is reduced
Evil, develops rainwater resource, and sponge urban construction is suggested as new urban construction theory.It sponge city can be as one piece of sea
It is continuous the same, rainwater is absorbed and is stored, it is recycled, and reduce the pollution of initial stage big flow rainfall runoff, nature calamity is faced
It being capable of elasticity adaptation when evil and environmental change.Sponge urban construction be by traditional " fast row " Mode change " ooze, be stagnant, storing, is net,
With, row " combination, reduce Urbanization Progress to the full extent and build to come to former natural hydrological characteristics and water ecological environment
Negative effect, to realize natural accumulation, naturally osmotic, self-purification to rainwater.The water penetration on road and square road surface will
It plays an important role to the infiltration of rainwater, delay, savings and purification, the wherein research of water-permeable brick and application is on the increase.It is permeable
Brick needs to have high water-permeability, water-retaining property and multifunctionality, puts goods on the market already in foreign countries, receives pass at home in recent years
Note.
It can be divided into cement base water-permeable brick, sintering brick permeable to water and resin base water-permeable brick by bonding mechanism permeable pavement brick.Cement
Base water-permeable brick will be gathered materials by inorganic coagulation material cement to be bonded together, sintering brick permeable to water then by high temperature resistant gather materials between high temperature
It is formed and is bonded after adhesive melting is cooling, resin base water-permeable brick is then mostly using hydrophilic thermosetting resin as binder.Sintering is saturating
The intensity of water brick and resin base water-permeable brick is generally higher, and flexural strength reaches 5MPa~7MPa, and compression strength is higher than 40MPa, very
65MPa can extremely be reached, coefficient of permeability is between 1 × 10-2Cm/s~10 × 10-2cm/s.The intensity of cement base water-permeable brick is then opposite
Relatively low, compression strength is generally 30MPa or so, and internal void substantially belongs to grade, therefore coefficient of permeability is higher, Ke Yida
To 0.1cm/s~0.2cm/s.Although sintering brick permeable to water and resin base water-permeable brick intensity are better than cement base water-permeable brick, there is system
The bottleneck problem that about they develop：Sintering brick permeable to water need to be generally 1000 DEG C~1200 DEG C through high temperature firing, sintering temperature, energy consumption
It is higher；Green body after firing may be deformed rupture in cooling procedure, and yield rate is made to reduce, and especially apparent size misses
Difference is relatively large, and production cost is higher；Resin base water-permeable brick is easy aging, especially epoxy cure body under light and heat effect
Ager process can aggravate in the presence of having water, and water-permeable brick durability is made to significantly reduce, and Years Of Service shortens.
Water-permeable brick is broadly divided into two classes from technique, and one kind is maintaining water-permeable brick, the raw material of water-permeable brick is crushed,
Suitable particle size range is chosen in screening, adds the mixing of the auxiliary materials such as binder and water, is then placed in mold and uses
Certain pressure compression moulding is placed maintenance, is made with water permeability and standard compliant paving material after being demoulded
Material.Another kind is slug type water-permeable brick, will prepare the raw material of water-permeable brick by broken, screening, compounding, mixing, molding, demoulding,
The series of processes such as high temperature burning, are made with water permeability and standard compliant paving material.
Raw material that maintaining water-permeable brick uses itself cannot contain other harmful substances such as heavy metal ion.Because of maintaining
Water-permeable brick is in the long-term erosion process of rainwater, and harmful substance can yield and comply rainwater and flow into soil and urban groundwater, to city
It is polluted with environment.Therefore, maintaining water-permeable brick major defect is that have certain limitation in raw material selection, and produce
Period it is long, itself be to be solidified togather by binder, due to the pyrocondensation cold expanding of water, on northern cold ground
Area's frost resistance is poor, and service life greatly shortens.Advantage is that energy consumption is relatively low in its preparation process, and production process is substantially zero
Energy consumption economically considers highly beneficial to enterprise.
Slug type water-permeable brick can select most of solid waste to prepare, because of meeting in the case of high-temperature calcination
Most of harmful substances are removed, the pollution to environment is reduced, heavy metal ion can also be solidificated in water-permeable brick, prevent its stream
Enter in soil and urban groundwater.The advantages of slug type water-permeable brick is that the water-permeable brick production cycle is shorter, raw material use aspects can
It is prepared with choosing more solid waste substances, reduces pollution of the solid waste to environment, and slow down a large amount of solid waste
When stacking the problem of waste land resource, economic benefit and environmental benefit are promoted, itself passes through porcelain after high temperature sintering, tool
There is preferable frost resistance, the service life in cold district can be greatly promoted.The disadvantage is that being needed in sintering process using natural
The energy such as gas or electric power, it is big many relative to the input of maintaining water-permeable brick economically.
The mix-design of concrete permeable brick mainly considers its intensity and water penetration.Its intensity is viscous mainly by cement mortar
Contact point, face between knot aggregate, therefore cement mortar glues intensity height, then the intensity of product is just high.Since the grading of aggregate is to disconnect
Grading generates some apertures between aggregate and leakiness, between them, forms the channel of water, i.e., so-called permeable.Aggregate size is got over
Carefully, gap is smaller, and water permeable ability is with regard to poor, but its intensity is high；Aggregate size is thicker, then fewer, sky is contacted between particles of aggregates
Gap is bigger, and water permeable ability is better, but its intensity is low, and the high-strength cement at this moment needing higher cohesive force bonds.
In general, the aggregate stone that base-material uses is divided into 4 kinds of ranks：2.5~5mm of grain size be the 1st rank, grain size 5~
10mm is the 2nd rank, and 10~20mm of grain size is that 3rd level is other, and 20~31.5mm of grain size is the 4th rank.It is got over using the rank of stone
Height, product strength is lower, but water penetration is better.In the certain range of water consumption, cement consumption is few, then intensity is low, but permeable
Property is preferable, and vice versa.Identical in cement consumption, strength of cement is higher, and adhesion strength is higher；Strength of cement is got over
Low, adhesion strength is lower.
Fabric generally uses quartz sand or Machine-made Sand, the intensity and wearability relative mistake of Machine-made Sand a little.But quartz sand due to
Kind is different, wearability also difference.Face layer sand it is high-quality, intensity is just high, and wearability might as well.In certain cement consumption
In range, cement consumption is more, and intensity is high, wear-resisting, but bad hydraulic permeability；Cement consumption is few, and intensity is low, not wear-resisting, but good water permeability.
With the quartz sand of kind, rubble sand is more wear-resisting than fine quartz sand, but product strength is low, permeable good.Face layer intensity effect full sized brick
Intensity, although base's cement is used less, the intensity of full sized brick is also higher.70% is accounted for using the particle of 2.36~1.18mm of grain size~
The quartz sand water-permeable that 90% quartz sand accounts for 80%~90% than 1.18~0.6mm particles is good, wear-resisting, but intensity is slightly
Low, surface is rougher.In short, it is necessary to find out to make high water-permeable brick intensity, wear-resisting, water penetration and good match ratio.
