Product Description:

Geocomposite 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.


Features of GCL:

A:Form high density diaphragm under hydraulic pressure, the water permeable capability equals to 100 times density degree of 30cm clay when the thickness of GCL is 3mm. It has very good self water-retention property.

B:GCL is nature inorganic material, it won't aging or corrode even after long-time or surrounding changed, so it has permanent water proofing capability.

C:GCL is nature inorganic material, which is non-poisonous and harmless to human body, so it is environment protection material.

Application Filed of GCL:

  • Water storage, miniature reservoir, dam of reservoir, acequia,fish pond

  • Roof garden, basement etc.

  • Subway, railway, expressway, light industry, oil and metallurgy and other industry

  • Maintenance, repair and reinforcement of earth works

  • Environmental reform, garbage landfill, artificial lake or other landscape

Q:Help students learn sister, civil engineering materials
Concrete: ordinary concrete, high strength and high performance concrete, fly ash concrete, light concrete, special concrete
Q:What is the difficulty of civil engineering materials?
Learn it very simple ah, if you want to engage in scientific research, then it is a bit difficult
Q:What is the civil engineering material
Some material shopping guide
Q:Which version of the material mechanics (author) is suitable for civil engineering this profession?
Structural mechanics, "structural mechanics", "river dynamics", "geotechnical principles", "soil mechanics and environmental geology", "steel", "elasticity theory", "elastic theory" (upper and lower volumes) Structure of the basic principles "(second edition)
Q:Why study civil engineering materials?
Understand the construction is mainly used to what material, not the time you do not know anything.
Q:Is the glass made of wood?
The civil material is clearly defined and does not contain glass
Q:Civil Engineering Materials
And other materials, autoclaved aerated concrete block drying shrinkage, moisture expansion. In construction applications, if the drying shrinkage is too large, in the presence of constraints to prevent deformation, the shrinkage of the formation of the stress exceeds the tensile strength or bond strength of the product, products or seams will appear cracks. In order to avoid cracks in the wall, must be in the structure and construction to take certain measures. And strictly control the moisture content of the product when the wall is also extremely important, it is best to control the wall moisture content of 20% or less
Q:Civil engineering materials on the prospects for talent employment, a little more
Now the employment environment is bad, many famous university graduates can not find counterparts work, it is recommended to carefully choose to read the professional, we must consider the employment problem, do not let yourself regret
Q:What are the four major mechanics in civil engineering?
Should be theoretical mechanics, material mechanics, structural mechanics, soil mechanics
Q:The Importance of Civil Engineering Materials in Engineering Construction
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.
