CJ/T 486-2015Soil stabilizing admixtures (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces CJ/T 3073-1998 "soil curing agent." The main technical changes compared with CJ/T 3073-1998 are as follows.

--- Modify the standard name;

--- Increasing the scope of the standard applicable soil curing admixture;

--- Increasing the normative references;

--- Clear the definition of soil curing admixture, add or delete the relevant definitions;

--- Modify the product classification and marking;

--- Removed liquid soil solidified additive solid content and stability requirements;

--- Increasing the homogeneity index, stability of liquid soil-curing admixture, soluble heavy metal ion content and water-stable ratio Claim;

--- Modify the unconfined compressive strength and setting time requirements;

--- Increasing the homogeneity index, liquid soil solidification additives stability, soluble heavy metal ion content and water stability coefficient of the test method;

--- Modify the inspection rules;

--- Modify the product logo, packaging, transportation and storage.
