Product Description:

Geocomposite Geosynthetic Clay Liner/GCL

 

 

Introduction:

 


Mass per unit ≥ 4000g / m²

 Width: 4-6 m 

 size: 5.8 x 30m , or customized 

 bentonite sandwiched between two layers of geotextile

 
Features:

 


1) Environment friendly. Liu Fangzi GCL is made of natural raw materials of sodium bentonite. Aging and corrosion never happen. It can keep its quality and then it does not cause any injuries and pollution for human and the environment. It is not only waterproof, but also has good ventilation performance. It can stick up for the exchange of the ecological environment. It is a pure natural, new, green waterproof material.

2) Permanent waterproof, excellent performance. Natural sodium bentonite has been formed for billions of years.Its waterproof properties are much longer than that of the buildings. Sodium bentonite would transform to high density septum under hydro pressure. When the thickness is 3mm, the permeability is below a×10-11/sec(a=1~9), which equals to the density of 100 times of the clay with 30 mm thickness. Water retention performance is evident.

3) Easy to use. Bentonite powder, nails and washers are enough for connection and fixation. Construction is not constrained by weather conditions and it could be taken under cold or wet conditions. Bentonite powder is spread on overlap point. When water comes, GCL would be overlapped automatically. It has been so far the only material that starts the waterproof effect by water in the world. It is not necessary to take additional examination when the construction is completed. The repair works are easy in case of waterproof defects. Among the existing waterproof materials, GCL’s construction period is the shortest and its operation is the easiest. It has an eminent effect on shortening the construction period as well as saving the cost.

4) Strong Self-Restore Capacity. The integration between waterproof material and its target enables GCL a 20~28 times swelling volume. Even if concrete structure trembles or subsides, the bentonite in GCL would restore the crack of 2mm or below on the concrete structure immediately. Even if the diameter of perforation reaches 30 mm, the restoration will be finished within 15 days completely.

Q:Help students learn sister, civil engineering materials
Non-mechanical hard cementing materials: lime, gypsum, water glass, magnesia cementitious materials
Q:What is the relationship between the development of civil engineering and the material and the theory?
There are three major mechanics in civil engineering; theoretical mechanics; material mechanics; structural mechanics. The discovery of mechanics has also reduced the cost of engineering.
Q:What are the raw materials for civil engineering?
Engineering need to do the re-test of raw materials: steel, brick, cement, sand, stone (if it is not a commodity concrete) waterproof coating, waterproof membrane
Q:Why the ancient Chinese architecture to civil materials, while the use of stone in Europe it?
May have a relationship with the feng shui wood fire show that prosperity
Q:Briefly describe the technical requirements of civil engineering for the use of its building materials and explain its reasons
Because the building materials in the civil engineering are used for all aspects of structure, finishes, insulation, filling and so on, there is a need for physical and mechanical technical requirements for building materials to meet the practicality, functionality, durability and beauty of buildings or structures The need for sex.
Q:What is the difference between building materials and civil engineering materials?
Building materials can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, brick, ceramic, glass engineering plastics, composite materials, etc .; decorative materials, including a variety of coatings, paint, coating, veneer, colored tiles, with special effects of glass Etc .; special materials that used for waterproof, moisture, corrosion, fire, fire, noise, insulation, insulation, sealing and so on.
Q:What are the interrelationships between the nature of the civil engineering materials described in this chapter?
In engineering practice, the selection, use, analysis and evaluation of materials is usually based on its nature.
Q:What are the major civil engineering courses?
Mechanics: theoretical mechanics, material mechanics, structural mechanics, of course there are many other, including advanced mathematics, English, painting geometry, surveying, etc.
Q:Questions about civil engineering materials
Elimination of concrete structural damage factors: In addition to environmental factors caused by the destruction of concrete structure, the concrete itself, some physical and chemical factors, may also cause serious damage to the concrete structure, resulting in concrete failure. Fourth, to ensure the strength of concrete High-performance concrete in the preparation of the characteristics of low water-cement ratio, the choice of high-quality raw materials, in addition to cement, water and aggregate, must be mixed with a sufficient amount of mineral aggregates and superplasticizer, The amount of concrete to reduce the internal porosity, reduce volume shrinkage, improve strength and improve durability.
Q:Civil engineering and new materials, which is a good job
Obviously civil, our school is now the situation is graduated in 2017, the civil has been signed, the work tube has not yet begun. Said the prospects of the big tube, a little self-deception, civil construction of the size of the project manager is the vast majority of civil origin, the number of project managers can be ignored, the construction company executives are mostly civil, budget origin. To say that the real estate management of the dominant, just a little funny, real estate is simply not willing to go to the civil, to learn nothing, grow very slowly, most people are more willing to do a few years in the construction unit to go to real estate, Then much more understanding, the growth rate is much stronger than the tube. Since you have learned the civil estimate you know some, if you are a boy, not the kind of people who can not eat a bit bitter, it is recommended not to turn the work tube, the other pipe is relatively simple, the management of things want to learn to get started And soon, if necessary, can work to learn. Of course, the benefits of the work tube, graduated from the management of the degree, but like the general school of this degree of gold can not agree with the degree.
