COMPLEX ADDITION TO GROUTING MORTAR BASED ON PORTLAND CEMENT

摘要

FIELD: well drilling, casing oil and gas wells. SUBSTANCE: complex addition to grouting mortar based on Portland cement has carboxymethyl cellulose and commercial sodium sulfate that is the waste of sebacic acid production. The acid is produced by neutralization of salts of fatty acids of sulfuric acid. Initial ingredients are as follows (% by weight): 17.3 - 50.0 carboxylmethyl cellulose, 50.0 - 82.7 sodium sulfate of commercial grade. EFFECT: decreased water separation.
