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 is the civil engineering material
Mainly material procurement, there are some other
Q:What is the course of civil engineering materials?
First of all, if you are studying the basic nature of the most basic civil materials (such as concrete, gravel, etc.), how these materials such as mix ratio and particle size affect their performance, as well as the details of these materials Division, after learning this has a general understanding of this.
Q:Now undergraduate civil engineering, what courses, which textbooks?
Main courses: engineering mechanics, fluid mechanics, rock mechanics, foundation and foundation, engineering geology, engineering hydrology, engineering drawing, computer application, building materials, concrete structure, steel structure, engineering structure, water supply and drainage engineering, construction technology and management
Q:Civil engineering materials, the material strength and brittleness to enhance the plastic reduction method
Plus point plus cross-linking agent
Q:Detailed classification of civil works?
By chemical composition: can be divided into inorganic materials, organic materials and composite materials.
Q:Read materials science and engineering or civil engineering, it is tangled ah, we discuss together!
If you consider employment, or read civil, if you want to do some academic, or read the material, rough for reference only.
Q:What is the meaning of the wetting angle in civil engineering materials?
When the wetting angle is less than 90 °, it means wetting, and if it is more than 90 °, it will not wet.
Q:Briefly describe the technical requirements of civil engineering for the use of its building materials and explain its reasons
As the pavement material, asphalt mixture, wear resistance, tensile strength, high temperature stability and durability, etc .; as the roof Waterproof material, the need for tensile strength, elongation at break, low temperature flexibility, impermeability, anti-aging properties
Q:Material science and civil engineering which is better?
Definitely civil engineering is good
Q:The Relationship between Water Absorption and Water Content in Civil Engineering Materials
The amount of water absorbed and the moisture balance in the air is usually less than the water absorption when the material in the air to reach saturation in the water, the water content and water absorption equal.
