METHOD FOR PRODUCTION OF SOLVENT MIXTURE Russian patent published in 1998 - IPC

FIELD: building materials production; production of solutions used to seal joints of concrete articles and reinforced articles; technology for production of protective coatings. SUBSTANCE: cement (with quantity 27.6-43.5 %) is mixed with water at their ratio 0.8-1.2. The process is carried out in rotary-pulse device. Piperylene oligomer (its quantity being 1.6-10 % of total cement mass) is added into said device and mixed there within 1.5-2.5 min. Suspension is added into mixture of sand with residual portion of cement and water. Coefficient of hardiness of solution is 0.99-1.0, coefficient of its water resistance is 1.0; its modulus of elasticity is (21.78-27.80) $$$ MPa, relative elongation is (14.7-16.2) $$$ mm. EFFECT: improved efficiency. 2 tbl
