Product Description:

                                       sodium Bentonite Geosynthetic Clay Liner(GCL) for anti-seepage

 

1,Introduction

 

GCL is a new geosynthetics. It is graded by a natural sodium bentonite particles and corresponding additive mixed together, By special technology and equipment, the bentonite particles between two layers of geotextile fixed, made of waterproof blanket, with all the characteristics of both the geotextile material, but also has excellent water (infiltration) performance.

 

2,Feature

(1) A permanent waterproof performance, and excellent water seepage performance, impermeability hydrostatic pressure up to 1.0MPa above, permeability coefficient 5 *10-9cm / s. Because the Department of Natural sodium bentonite inorganic materials, even after a long time or the surrounding environment changes, aging or corrosion does not occur.

 

(2) Has all the characteristics of geotextile material, such as separation, reinforcement, protection, filtration, simple construction and unrestricted construction environment temperature below 0 0 C also be construction. Just when construction GCL waterproof blanket tile on the floor, when the elevation or slope construction, with nails and washers to secure it, as required, can overlap.

 

(3) Easy to repair; Even after water (seepage) end of construction, such as waterproof layer accident damage, as long as the site of the damage to be a simple fix, can ever regain perfect waterproof performance.

 

(4)green: Bentonite is a natural inorganic material, harmless, non-toxic, no particular impact on the environment, with good environmental performance.


(5) simple construction period is short: and other waterproof materials, the construction is relatively simple, does not require heating and paste. Product width up to 6 meters, with international geotextile (film) to match the size, greatly improving the efficiency of construction.

 

(6) Integrated waterproof materials and objects: When sodium bentonite water, with 20-28 times the capacity expansion, even if the concrete structure vibration and settlement, bentonite GCL can repair cracks in the concrete surface less than 2mm.

 

3,Application

(1)Municipal engineering, underground engineering subways, buildings and roofs reservoir seepage.

(2)Environmental sanitation, solid waste landfills, sewage treatment plants, industrial waste.

(3)water, rivers, lakes and reservoirs dam seepage, plugging, reinforcement.

(4)Garden artificial lake golf course pond seepage and so on.

(5)Petrochemical, mining and other areas of engineering seepage, leakage, etc.

Q:What are the types and properties of commonly used civil engineering materials?
According to the use of functional classification According to the civil engineering materials in the building parts or the use of performance, can be divided into building materials, wall materials, building functional materials three categories.
Q:Questions about civil engineering materials
Elimination of concrete structural damage factors: In addition to environmental factors caused by the destruction of concrete structure, the concrete itself, some physical and chemical factors, may also cause serious damage to the concrete structure, resulting in concrete failure. Fourth, to ensure the strength of concrete High-performance concrete in the preparation of the characteristics of low water-cement ratio, the choice of high-quality raw materials, in addition to cement, water and aggregate, must be mixed with a sufficient amount of mineral aggregates and superplasticizer, The amount of concrete to reduce the internal porosity, reduce volume shrinkage, improve strength and improve durability.
Q:Definition of civil engineering materials
At present, from the narrow sense of the definition, civil engineering is equivalent to civil engineering, that is, construction (or structural engineering) this small range.
Q:Civil engineering materials in the two grinding a burning what does this mean
Refers to the cement material, cement is the first stone and other raw materials, grinding, and then after high temperature calcination, and then after grinding into powder
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 raw materials for civil engineering?
There are three large series of buildings, civil, electrical, plumbing, civil steel reinforced concrete, is called 3 large, masonry, commodity concrete, turnover, waterproof, paint, flooring, small materials
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:Civil engineering, machinery, materials and finance which relatively good employment?
Of course, is the civil ah I give you analysis of the material of the wide range of professional employment, but the depth is not enough wages ah what is not ideal employment rate is not too high (I am the material you do not be his name scared) unless you are Submit the material of the professional or you decide to study the future
Q:Civil engineering materials learned what is the use, how to apply to the community, work on!
Civil engineering materials, the most important point of knowledge is certainly concrete, after the work of civil engineering is basically inseparable from the open. Material This course is a basic understanding, to understand the knowledge, followed by the use of knowledge, such as the future to do a project, according to the engineering environment to use different characteristics of the concrete. If you say that is life, after all, this course called civil engineering materials, mainly to introduce you are used in civil engineering materials.
Q:Briefly describe the technical requirements of civil engineering for the use of its building materials and explain its reasons
For example, as the structure of reinforced concrete requires mechanical properties of the requirements: such as strength, elastic modulus, shrinkage and so on; physical properties, apparent density, impermeability and durability
