Who knows what GCL refers to in geotechnical materials?

Answer:

The construction is simple and the construction period is short. Compared with other waterproof materials, the construction is relatively simple, without heating and pasting. Only with bentonite powder and nails, gaskets and other connections and fixed. No special inspection is required after construction, and it is easy to repair if water proof defects are found. GCL is the shortest construction period in existing waterproof materials.
The integration of waterproof materials and objects: sodium bentonite and water reaction, with expansion capability of 13-16 times, even if the concrete structure vibration and settlement, GCL bentonite can repair the concrete surface crack is less than 2mm.
Not affected by temperature: it is not brittle in cold climates.
The permanent waterproof properties: because sodium bentonite series natural inorganic material, even after a long time or the surrounding environment changes, also does not occur, aging or corrosion, therefore durable waterproof performance.
Density: high density diaphragm sodium bentonite formation in the hydraulic condition, the thickness of about 3mm, its permeability is alpha? 10-11m/sec, density 30cm is equivalent to 100 times the thickness of the clay, has a strong self water performance.
