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:On the Title of Civil Engineering
After graduating from one year after graduation to assistant engineer, as assistant engineer after four years of assessment engineers. If you are engaged in the construction of the building on the construction division to do a certain time after the test of a supervision engineer. If you engage in the settlement of the test on the cost of division or economist. If you engage in the design of the architect or architect or rock division. A supervisor of the supervision of the engineers. Of course, can more work to more test on the test. The supervisor of the maximum number of years so the final test budget, construction workers, quality inspectors, security officers, materials
Q:What are the main features of gypsum for civil engineering materials?
Has a certain humidity, fire resistance, water resistance, poor frost resistance
Q:What are the classification of civil engineering graduate students?
After graduation, the main employment units in the past three years, the supply and demand ratio of graduates 1: 6. After graduation in the housing construction, geotechnical and underground engineering, road and bridge engineering and other civil engineering design, construction, management, investment, real estate development, research and education departments engaged in technical or management work.
Q:What is the meaning of the wetting angle in civil engineering materials?
English name: wetting angle Definition: liquid and solid phase contact point at the liquid-solid interface and liquid surface tangent angle.
Q:Civil Engineering Materials.
Civil Engineering Materials. e Material saturated with water, and then dry the surface, is the hole filled with water or closed hole filled with water? What is the condition of putting the material in a jar filled with water? Not to say that the closed hole is not water?
Q:What is civil engineering and architecture?
The main disciplines of civil engineering: theoretical mechanics, material mechanics, structural mechanics, fluid mechanics, soil mechanics, building materials, concrete structures and steel structures, housing structures, bridge structures, underground structures, road survey design and roadbed pavement structures, management.
Q:What are the requirements for civil engineering materials?
I think it's a requirement. The The Product to be qualified
Q:What are the three mechanics of civil engineering?
Civil engineering is the planning, construction and maintenance of everything related to water, soil and culture. At present, general civil works include roads, water conservancy, drainage, disaster prevention and transportation. In the past, all non-military civilian projects were classified into this class. However, as engineering science became more and more extensive, many of the original contents of civil engineering had become independent.
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:Will the mechanical material mechanics and civil material mechanics different?
Material mechanics is a course, not too much difference in our university material mechanics examination questions are the same as the late course of the different civil class tend to focus on geotechnical mechanics, non-linear analysis of the mechanical class more Concerned structural analysis, elastic mechanics
