Additive used for treating clay/salt in situ materials in order to turn them into aggregates for cement mortar and cement concrete

摘要

The invention relates to an additive (named CSSB) generally comprising (by weight): 10% to 50% of polymer solution; 10% to 20% of alkyl benzene sulfonate; 5% to 10% of sodium carbonate or sodium phosphate; 2% to 10% of sulfuric acid and 10% to 73% of saltwater or salt-contaminated water. The CSSB additive is used for treating clay and salt in unsuitable in situ building materials, such as soil, soil containing clay, clay containing stone, clay containing sand, gravelly soil, saline-sand, and saline contaminated water in order to turn them into aggregates for cement mortar and cement concrete. The invention also relates to methods for making cement-mortar and cement-concrete by using such additive which incorporates such aggregates.
