AERATED CEMENT MORTAR COMPOSITION Russian patent published in 2001 - IPC

FIELD: well drilling. SUBSTANCE: cement mortar composition designed for lining wells and also for monolithic construction to form heat-insulation material contains binding agent, blowing agent, structure-forming agent, air, and water. Structure-forming agent is china and faience production waste in the form of paste composed of, wt %: dolomite 20-30, sodium silicate 12-20, silica 15-20, kaolin 10- 15, faience frit 10-20, and water. EFFECT: increased plastic strength in early cement mortar hardening phase and increased sedimentation stability of nonshrinking clogging stone due to increased homogeneity and conformity to theoretic density in the range of 800-300 kg/cubic meter. 1 tbl, 3 ex
