Product Description:

Sodium Bentonite Geosynthetic Clay Liner 

 

Introduction of GCL:

Geosynthetic Clay Liner is manufactured 

by three levels, including two levels of geotextile whose functions are protecting and strengthen to ensure   shearing strength and tensile strength, inner content is Sodium bentonite clay. It is manufactured by nature layer silicate inorganic materials and has high expansibility and high water-absorbing capacity, when soak with low permeable capability, whose the main function is anti-seepage.

 

Description of GCL 

Unit weight ≥4000gsm

width of 4-6m

 Compared with clay liner ,it has the advantages of small size,light weight ,good flexibility and sea

 easy for construction and suitable for uneven settlement.

 

GCL Feature:

  

1.The permanent waterproof

 

Because sodium base bentonite is a natural inorganic material, even after a long time or the surrounding environment changes, 

also won't happen aging or corrosion phenomena, so the waterproof performance persistence.

 

2. Compactibility

 

Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, 

its permeability is 5 x 10-11m/SEC below, equivalent to 100 times the compactness of 30 cm thickness of clay, 

have very strong since the water retention performance.

 

 

3.Not affected by temperature

 

In cold climates will not brittle fracture.

 

 

4.Environmental protection

 

Bentonite as natural inorganic material, non-toxic harmless to human body, no special effects to the environment, 

have good environmental performance.

 

 

5.Simple and short time of construction

 

Compared to other waterproofing materials, construction is relatively simple, don't need to be heated and paste. 

With bentonite powder and nails, washers, etc are connected and fixed. After construction does not need special

inspection, if it is found that the waterproof defects and easy to maintenance.

GCL is existing waterproof material in construction period of the shortest.

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.
Q:Material in the civil engineering in what kind of position
Very important. You have to know, civil engineering in every link with the material is closely related. Concrete structure of cement and steel, steel structure in a variety of steel, are common materials.
Q:Civil engineering materials stone test, the determination of stone grade with what practical significance?
Select the best proportion of aggregate, for the preparation of concrete with the ratio.
Q:Are building materials the same as civil engineering materials?
Civil engineering includes a wide range of materials, except for buildings, roads, bridges, tunnels and geotechnical materials that are related to civil engineering materials, but many of these materials are not used in industrial and civil construction.
Q:Civil engineering graduation, after work which test is good?
Examination level Primary, intermediate, advanced
Q:Civil engineering materials in the two grinding a burning what does this mean
Refers to the cement material, cement is the first stone and other raw materials, grinding, and then after high temperature calcination, and then after grinding into powder
Q:What are the main properties of the materials used in civil engineering requirements?
Rigidity, strength, stability, durability and so on
Q:Definition of civil engineering materials
The so-called large civil. Refers to all water, soil, culture-related infrastructure planning, construction and maintenance. At present, the general civil works include roads, water services, drainage services, flood control works and transportation.
Q:Detailed classification of civil works?
According to its use: can be divided into structural materials, decorative materials, waterproof materials, insulation materials, etc .; according to its function: can be divided into structural materials, decorative materials, waterproof materials,
Q:Why is material durability so important in civil engineering?
In civil engineering, each project provides a certain number of years of use, generally at least 50 years, the construction has its function, he wants to human life and production services, think if you repair a building, with less than 5 years can not afford to wind and rain, hot and cold erosion and crumbling, which is not only a waste of financial and material resources, but also people's lives and property do not respect, not responsible.
