Loess composition and clay floor construction method

摘要

The present invention relates to a loess composition for preventing shrinkage cracking due to moisture evaporation and a method for the construction of a loess soil, comprising 97.6 to 99.99 parts by weight of loess; 2.4 to 0.01 parts by weight of a mixture A consisting of hydrated alkaline silicate, 1 to 3% by weight of kaolin, 4 to 6% by weight of diazonaphthalene, 12 to 16% by weight of sulfonic acid and 75 to 83% by weight of water; And the loess composition containing 10 to 1000 times water based on the weight of the mixture A and the loess composition are applied to the floor and then subjected to compaction after 15 to 50 hours have elapsed.;In the case of using the loess composition, it is possible to prevent the leakage of water and gas by suppressing shrinkage cracks generated during drying, and to improve appearance.
