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:For the civil engineering students, material mechanics need to grasp to what extent?
Are you civil Material mechanics is the branch of the three major mechanics, of course, important, the design of the basis of the need to clearly grasp the material mechanics, such as the size of the beam design and check these in the engineering practice are directly used, many famous university entrance examination course is material Force rather than knot force can see its importance
Q:What are the types and properties of commonly used civil engineering materials?
Generally classify the various classification methods by appropriate combination of materials after the division. Such as decorative mortar, asphalt waterproof material.
Q:Material in the role of civil engineering in which should be the main understanding
4, some materials may need to re-examination, the need for timely submission of materials, and with the approach material corresponding. 5, for the emergence of the scene material loss, the need for material to be reported in a timely manner.
Q:Material in the civil engineering in what kind of position
You said that material important is not important. It can be said that the material is the cornerstone of civil engineering. No material what is the air castle.
Q:What is the course of civil engineering materials?
First of all, if you are studying the basic nature of the most basic civil materials (such as concrete, gravel, etc.), how these materials such as mix ratio and particle size affect their performance, as well as the details of these materials Division, after learning this has a general understanding of this.
Q:Who knows civil engineering materials?
Slag cement, early strength fast.
Q:Why the ancient Chinese architecture to civil materials, while the use of stone in Europe it?
Ancient China mainly lived in the northern Yellow River basin, and later gradually migrated to the south, and the Yellow River Basin and the original trees and less stone, so the majority of the main civil construction, and the European stone Hill more stone is also sufficient, many of the original is lean stone mountain Built, can be local materials, so the majority of stone construction
Q:The relationship between material development and civil engineering development
The The product of modern technology development in recent decades. It is a variety of raw materials, with advanced processing methods, made in line with modern building requirements, with light, high strength, multi-functional and other major features of modern building materials; in general, it also has energy saving, The advantages of comprehensive utilization of resources. The emergence and de
Q:Civil engineering commonly used materials which four kinds
Mainly steel, cement, stones, sand
Q:What are the three categories of civil engineering materials classified according to the basic composition?
According to the material is divided into inorganic materials, organic materials, composite materials, metal materials.
