Product Description:

GCL Sodium Bentonite Liner Geosynthetic Clay Liners


 

 

Product Introduction

Geosynthetic clay liner is composed of high dilatability of sodium base bentonite filling between the special composite geotextile 

and nonwoven fabric, made by the method of acupuncture or suture composite impervious material. Use acupuncture into 

geosynthetic clay liner can form many small fiber space, make the bentonite particles can't flow in one direction, when under the 

influence of water within the mat forming uniform density of colloidal waterproof layer, prevent the leakage of water. 

For different projects,it can combine HDPE liner for better waterproof.

Bentonite has the expansion of the water characteristics. General calcium base bentonite expands, its expansion is only about 3 times 

their own size; And sodium base bentonite adsorption 5 times its own weight of water in case of water, Volume expansion to the 

original 15 to 17 times above; Lock sodium base bentonite in the middle of the two layers of geosynthetic materials, protecting 

and strengthening the role of, Make the GCL has a certain overall shear strength.

 

Geosynthetic Clay Liner

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 10-11 m/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:What are the courses in adult education and construction engineering?
Self-examination is also adult education, but self-examination course is fixed, but each province may not be the same, do not know which province you are, there is a specialist and undergraduate examination subjects
Q:Civil engineering graduation, after work which test is good?
I am learning civil engineering (road and bridge) for this problem, the prospect of civil engineering is still good, earn money is of course, of course, is difficult conditions, for the newly graduated students, I suggest or to the construction line to exercise, Also 5 years or so, naturally you will be transferred back to the city, the premise is to rely on their own efforts! When a project manager is easy, you are basically in the city stay, live a hotel is very good! For these documents it is slowly test, there are years! Construction division is not worth the money, 3 years is about 15000! Wait until the engineer intermediate title on the more test card! Just graduated from the test is the secondary construction division, according to the theory you can not test this year!
Q:The Relationship between Water Absorption and Water Content in Civil Engineering Materials
The amount of water absorbed and the moisture balance in the air is usually less than the water absorption when the material in the air to reach saturation in the water, the water content and water absorption equal.
Q:Civil Engineering Science and Technology Examination
This is related to the school you have to apply, most of the civil engineering materials mechanics and structural mechanics
Q:Civil engineering materials, the material strength and brittleness to enhance the plastic reduction method
Reinforcing steel cold (cold drawing, cold drawing), can improve the strength and brittleness; plasticity.
Q:Seeking 3500 words civil engineering materials, urgent use
In the process of implementation of the project, the details of the management of engineering materials to what point as a starting point to what purpose? It is necessary for everyone to discuss, to foreword in the iron seven companies three companies listed companies "China Railway Co., Ltd." three subsidiaries , Railway, highway, municipal engineering "project general contracting a qualification" large and medium-sized enterprises. Year work conference, the company's general manager He Jiang advocated the project "detail management", the company up and down the management of a great touch, but also that the implementation process of the project full, the whole process of labor costs, material costs, , The details of the project cost of the project management in the implementation of the project, inspired.
Q:Characteristics of Modern Civil Engineering Materials
Innovation, such as in recent years in the domestic application of a wide range of foam light soil, pipe piles, etc., not necessarily high-tech, but can be very good to meet the practical application of the project, and have good economic benefits and treatment results.
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:Why civil engineering to solve the problem is to give full play to the role of materials
Cost-effective, with its own things have their price Well High-end material performance is good, the same high price, if the project does need this high-end materials to meet the construction requirements, it can only use this, because the general material will cause engineering quality problems. However, if the general performance requirements, that is, ordinary materials can be resolved, then use ordinary materials like, without the need for high-end materials, which can save costs.
Q:What are the civil engineering materials?
Cement: general portland cement, ordinary portland cement, a large number of mixed materials, Portland cement
