Product Description:

                                       sodium Bentonite Geosynthetic Clay Liner(GCL)

 

1,Introduction

 

bentonite geotextile clayliner is composed of 3 levels. The upper level and the lower level are woven geotextile  and non woven textile. 

The middle level is bentonite grains, which are carefully selected crude and filled in between the two levels after special processing. 

The bentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof effect. 

 

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 is a civil engineering material?
From the narrow sense of the definition, civil engineering is equivalent to civil engineering, that is, construction (or structural engineering) this small range.
Q:The gap between China 's civil engineering building materials and abroad
I think the attitude of the subject can explain the most fundamental gap - the positioning of their own position and their own development of the positioning of many high-rise building, the world's top 100 high-rise buildings in China nearly half, and many very high degree of public construction. Feel the 1950s norms copy the Soviet Union until now, the basic theoretical framework has not changed, the relative development of disciplines, the relative cutting-edge areas may be the direction of the material, have nothing to do with the professional relationship. Domestic understanding is often even narrow to the same as the building structure of the project, the subject is so understanding, this is not wrong, but our time on the demand for civil resources in this only, does not mean that civil engineering itself.
Q:Advantages of the world famous universities
Psychology, history, philosophy, politics, life sciences, public health, business, earth sciences, medicine, chemistry, physics, biology, pharmacy, international relations, linguistics, classics, literature Life science, law, history, sociology, economics, literature, classics, politics Social science, computer science, science, law, earth science, energy science, history
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?
Material mechanics construction mechanics structural mechanics
Q:What is the difference between building materials and civil engineering materials?
Building materials can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, brick, ceramic, glass engineering plastics, composite materials, etc .; decorative materials, including a variety of coatings, paint, coating, veneer, colored tiles, with special effects of glass Etc .; special materials that used for waterproof, moisture, corrosion, fire, fire, noise, insulation, insulation, sealing and so on.
Q:Why study civil engineering materials?
The basic materials, material properties, quality requirements and testing methods of civil engineering materials commonly used in civil engineering are mainly introduced. The contents include inorganic hardening cement, cement, mortar, concrete, masonry and roofing materials, steel , Synthetic polymer materials, asphalt materials, wood, insulation materials, sound-absorbing materials and sound insulation materials, decorative materials, new waterproof materials, fireproof materials. This is of great practical significance in the construction and design.
Q:What are the interrelationships between the nature of the civil engineering materials described in this chapter?
Civil engineering materials are the material basis of civil engineering, the nature and quality of materials to a large extent determine the performance and quality of the project.
Q:Why civil engineering to solve the problem is to give full play to the role of materials
Cost-effective, with its own things have their price Well High-end material performance is good, the same high price, if the project does need this high-end materials to meet the construction requirements, it can only use this, because the general material will cause engineering quality problems. However, if the general performance requirements, that is, ordinary materials can be resolved, then use ordinary materials like, without the need for high-end materials, which can save costs.
Q:In addition to cement, but also add gelling agent
The role of adding gelling agent in cement mortar is to enhance the adhesion
