WATER-IMPERVIOUS MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a water-impervious material that has excellent water barrier properties, good plasticity and is easy to be constructed. SOLUTION: One hundred parts by weight (pts.wt.) of a water-impervious material including coal ash and bentonite are mixed with 30-60 pts.wt. of water to prepare the objective water-impervious kneaded material. The material has excellent water barrier properties with small water-permeation factor, good plasticity and satisfactory strength.
