Introduction Geosynthetic clay liners (GCLs) are a new generation of waterproof building materials, which are manufactured clay liners that consist of a thin layer of bentonite glued to a geomembrane or are encased by geotextiles [1,2].
However, how to improve the salt resistance capacity of GCLs in saline water using China bentonites as the raw materials has rarely been reported.
Materials and methods Materials used.
Because diatomite, opals, sepiolite, attapulgite are all porous materials, the specific area of which are large.

Therefore, making full use of non-wooden materials is an effective way to make up for the shortage of wood resources in China.
MATERIALS AND METHODS Experiment materials and equipment Wheat-straw material : being boiled with 12% NaOH in 150℃ for 4h and bleached with 5% H202 in 70℃ for 6 h; composed of 88.32% cellulose, 1.43% hemicellulose, 2.53% lignin, 3.28% ash.
It is good for reinforcing materials bause the higher the cellulose regularity, the higher strength it has8.
