What is bread brick
Bread brick is also known as the Dutch brick, originated in Holland, in the process of the Dutch enclosure of the sea to build the city, found that the discharge of seawater after the ground will be long term contact with the water caused by the continuous ground subsidence, once the dykes on the coastline is washed away, the seawater will be quickly rushed to the sea level than the city is much lower than the sea level to put a lot of the city to the sea. Sea level is much lower than the city to the entire city of the sea all submerged, in order to make the ground no longer sinking, the Dutch made a long 100 millimeters, 200 millimeters wide 50, 60 millimeters high small pavement bricks paved in the street pavement, and so that the brick in the brick between the reserved 2 millimeters gap, so that when it rains, rainwater will be seeped into the ground from the gap between the bricks, which is later on the very famous Dutch bricks.
After this, the United States Shubroco invented a brick body, when the brick body is full of water when the water will be discharged to the ground, but the drainage of this brick is very slow, in the rainstorm weather this brick is almost no help,, this brick is also known as the Shubroco pavement bricks.
In the nineties China appeared Shubuloke brick, our technicians according to the principle of Shubuloke brick invented a brick itself full of permeable holes, water permeability is very good pavement bricks, the rain will be from the brick body of the tiny holes in the flow of the underground.
After a period of time, in order to strengthen the compressive and flexural strength of the brick body, the technicians used crushed stone as raw materials, adding cement and colloidal additives to make its permeability speed and strength to meet the needs of the city pavement, this brick is the municipal road surface permeable brick, the price of this brick is relatively cheap compared to ceramic ceramic permeable bricks with ceramic firing.
Because of the better water permeability of the Dutch brick, is widely used in urban road reconstruction. It is also a popular industry for many investors to invest in at present.
What are the advantages of bread bricks
Bread bricks have good water permeability, air permeability, water retention, with cooling, noise reduction, climate regulation, improve air quality, maintain surface water circulation of a number of functions. Because of its appearance, it solves many problems.
Bread brick solves the problem of water on the road surface due to rain, which affects people walking. The emergence of permeable bricks is a good solution to the problem of groundwater sources, for the urban environment and urban green plants to provide the conditions for production.
Bread bricks used in urban sidewalks, stations, pedestrian streets, apartment parking lots, airports and other places, instead of cement, stone hardened pavement. It has become a popular paving stone of general interest and popularity.
Bread brick belongs to a kind of wear-resistant bricks, with a small brick surface volume, simple color of the brick body, mostly in the form of concave-convex surface. In this way it has the characteristics of anti-slip, wear-resistant and easy to repair.
1) anti-skid: bread brick surface rough appropriate, rain and snow days anti-skid;
2) does not collect water: bread brick permeability is good, and then with the caulking sand, the pavement collection of water quickly discharged to the ground, will not be due to the passage of the people and produce mud splash phenomenon;
3) sub-light: bread brick surface is rough and non-reflective, strong sunlight is also not blinding;
4) Permanent marking: various markings on the road such as lane division line, crosswalk, blind (with Hongle blind special bricks) and so on can be set up permanently by different colors of floor tiles.
5) Bread tiles from the choice of raw materials to the production, maintenance of environmental protection everywhere, tiles without any harmful radiation, while absorbing the sun's ultraviolet rays.
6) bread brick paving system better water permeability so that the foundation soil to maintain moisture, adjust the road surface temperature, reduce the urban air dust, improve urban comfort, the ecological environment around the pavement protection plays an important role
Bread brick paving method
1, bread brick grass-roots level
To be stained in the grass-roots level of the floating mortar, flooring ash, etc. with a burin or a wire brush to clean off, and then use a sweeping brush to clean off. Wire brush to clean up, and then broom the floating soil clean.
2, find the elevation
According to the horizontal standard line and design thickness, in the surrounding daughters of the wall popping up on the surface of the flat elevation control line.
3, row of bricks
The roof will be in accordance with the size of the brick size seam size, row of bricks placed in position, and at the grass-roots level to pop up cross control lines and compartmentalized lines. Row of bricks should be in line with the design requirements, when the design does not require, it is advisable to avoid the plate less than 1/4 side length of the corners.
4, laying combined layer mortar
Before laying, the substrate should be wet, and the substrate should be brushed with a vegetarian cement slurry or interface bonding agent, with the brush with the laying of a well-mixed 1:3 cement mortar, the thickness of 25mm.
5, laying bricks
Place the bricks in the combined layer, with a rubber hammer to find the level, and then the bricks will be lifted up, pouring the right amount of vegetarian cement slurry on the dry mix, while the back of the bricks are coated with the same time, the bricks will be poured into the dry mix, and then the brick will be poured with the same amount of vegetarian cement slurry. Cement paste, at the same time in the back of the brick coated thickness of about 1mm of vegetarian cement paste, and then placed in the brick looking for a flat dry mix, with a rubber hammer according to the elevation control line and square control line sit flat and sit right. Paving bricks should first be laid in the middle of the roof according to the cross line cross control bricks, and then according to the cross control bricks to the surrounding paving, and at any time with a 2m ruler and level ruler to check the flatness. Large area should be paved in sections and parts of the paving.
6, maintenance
When the brick surface layer paving finished within 24h should start watering maintenance, maintenance time shall not be less than 7 days.
7, away from the seam
Bread brick applicable sites
Plaza, school, parking lot, community green, parks, family yards and other places are suitable for paving lawn tiles.
What is the size of bread brick
Bread brick is divided into the following specifications
200X100X60(mm)150X150X60(mm)230X230X60(mm)
200X100X80(mm)230X115X60(mm) 300X300X60(mm)
200X200X60(mm)400X200X80(mm)400X200X60(mm)
Bread tile color classification
Bread tiles can be divided into red, yellow, black, soy sauce, blue, orange, etc.
Bread tiles production guide
Bread tiles production guide to select materials
(The so-called material is stone powder.) The selection of material is the key to make high strength bread tiles.
When the material is delivered, you need to see if the material is the right thickness. There is no soil. Here is how to choose the material.
1, transported materials to use the hand to grab a hand in the hand clutch. The general thickness of the appropriate material in the hands of the clutch will not have too solid feeling,
Too thick material in the hands of the clutch will not become a ball. Too fine material will be too fluffy. A clutch will be gone.
2, put the material into the mixer to add the appropriate amount of aggregate stone (generally according to the ratio of 4:1 is about the same) let the mixer mix a few rounds on the put
into the water (water and stone ratio is 10:1) and then put cement. Let the cement and stone mix well. After mixing well, use your hand to grab a handful
clutch. As long as it is a clutch stone molding. And there is a moist feeling in your hand is OK.
How much does a bread brick cost
Bread brick quality is not the same, the price is not the same, the general bread brick more than twenty dollars a flat.
