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:The Relationship between Water Absorption and Water Content in Civil Engineering Materials
Application of water absorption in the water to absorb moisture in the air that the method to absorb moisture to the mass ratio or volume ratio of moisture absorption ratio
Q:Civil engineering materials stone test, the determination of stone grade with what practical significance?
Adjust the proportion of sand, stone
Q:Characteristics of Modern Civil Engineering Materials
Understand the development trend of civil engineering materials With the development of human civilization and science and technology, civil engineering materials continue to improve and improve. Modern civil engineering, although the traditional soil, stone and other materials have been gradually dominated by new materials replaced. At present, cement concrete, steel, reinforced concrete is an irreplaceable structural material; new alloys, ceramics, glass, organic materials and other synthetic materials, various composite materials in the civil engineering fold occupies more and more important position.
Q:Discussion on the importance of materials in civil engineering
Different types of materials, mechanical coefficient, the construction method will be different, the impact of the construction process, the impact of the demand for materials, the impact on the cost of the project impact, the impact on the quality of the project.
Q:Civil engineering materials learned what is the use, how to apply to the community, work on!
Such as decoration in the identification of quality tile quality, tile quality is divided into excellent products, first-class goods, three qualified products. In addition to look at the appearance of color, the general can also look through the tile water absorption size, size deviation, angle Founder to identify the different levels of quality and price difference is very far, if you do not understand can not identify good or bad. There are water PP-R pipe, wire tube, wood floor, glass, and furniture (plywood, fibreboard, particleboard), etc., will you identify good or bad?
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:What is the difficulty of civil engineering materials?
Easy to say is easy, are memories of things, but did not learn a few good
Q:Civil Engineering Science and Technology Examination
Many of the professional and related to the test will be
Q:Questions about civil engineering materials
