METHOD OF PRODUCING DRY CONSTRUCTION MIXTURE FOR MAKING FOAM CONCRETE AND COMPOSITION THEREOF Russian patent published in 2013 - IPC C04B38/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a dry construction mixture for making foam concrete and composition thereof. The method of producing a dry construction mixture for making foam concrete involves separate preparation of a mixture of portland cement with a calculated portion of 30% oligopetide colloidal solution (OCS) in water and simultaneous preparation of a mixture of fine aggregate with particle size of 0-0.315 mm and microsilica with the remaining portion of said OCS, mixing and adding a metal sulphate, with the following ratio of components, wt %: portland cement 32-38, said aggregate 32-42, microsilica 13-20, said colloidal solution 10-14, metal sulphate 1-2. The dry construction mixture for making foam concrete is obtained using said method.

EFFECT: longer storage life of the dry mixture, high strength of foam concrete while maintaining its density.
