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:Civil engineering commonly used materials which four kinds
The first floor to answer the right, reinforced concrete gravel sand
Q:The role of materials in civil engineering
The material determines the form of a building or a structure. The material determines the form of the project. For example, the Sui Zhaozhou bridge is made of stone, stone is brittle material, despite the superb design skills, the material determines the span of Zhaozhou Bridge can not be too large, only 30 meters. This is already the stone used in the ultimate bridge! The application of modern high-performance concrete and high-strength steel bar is only possible to make the Hangzhou Bay Bridge, single span of more than 100 meters. The tower is also the case, the brick material of the Wild Goose Pagoda was 58 meters, while the modern material of the Dubai Tower has 818 meters. So the material is to restrict or determine the development of civil engineering.
Q:The Relationship between Material Development and Civil Development
The material is too important for civil engineering. Many need this knowledge
Q:Civil engineering, machinery, materials and finance which relatively good employment?
Civil engineering, basic in the construction industry, machinery, basic in the manufacture of factories or research institutes, materials, basic in research institutes, finance, basic in securities and civil servants, specifically with their own interests and home.
Q:Civil engineering graduation, after work which test is good?
Examination level Primary, intermediate, advanced
Q:What is the actual state of the bar in civil engineering?
(3) to understand and master the cross-section of the cross-section of the torque, torque diagram; (4) mastery of the straight and straight (2) to understand and master the thin-walled cylinder torsion; (5) master the deformation of the straight rod when the deformation, stiffness conditions; (6) to understand and master the straight rod when the strain energy .4 bending stress symmetrical bending of the The calculation of the concept and the calculation of the beam; the shear force equation of the beam and the moment equation, the shear force diagram and the bending moment diagram; the internal force of the plane frame and the curved rod; the normal stress and the normal stress strength condition on the beam cross- (1) to understand and master the concept of symmetrical bending and beam calculation diagram; (2) master the beam of the shear equation and bending moment equation, the shear force diagram of the shear stress, shear stress strength conditions; (3) to understand and master the plane frame and the internal force of the curved rod; (4) master the beam cross-section of the normal stress, normal stress strength conditions; (5) to understand and master the beam cross-section (6) Understand and master the reasonable design of the beam 5. Displacement of the displacement beam when the beam is bent; Define the differential equation and its integral; Define the displacement of the beam; Nuclear, to improve the stiffness of the beam measures; beam bending energy within the beam.
Q:Are building materials the same as civil engineering materials?
Should be almost the same, my class textbooks are civil engineering materials, class name building materials
Q:What are the interrelationships between the nature of the civil engineering materials described in this chapter?
In engineering practice, the selection, use, analysis and evaluation of materials is usually based on its nature.
Q:University of high polymer materials or civil engineering
There is not much freshman course, sophomore year is very much. I do not know how to bio-engineering, the worst job every year, the top spot in China there is no market. Several other two read out in general.
Q:What are the major civil engineering courses?
"Structural testing technology" "structural mechanics" "civil engineering construction" "geotechnical testing technology" "geotechnical" "housing architecture"
