IMPROVEMENT OF CONCRETE, MORTAR AND GROUT BY ADDITION OF RESIN /IN FRENCH/

THE MECHANICAL AND RHEOLOGICAL CHARACTERISTICS OF HYDRAULIC CONCRETES, MORTARS AND GROUTS DEPEND ON THE VOLUMES OF CEMENT, WATER AND AIR CONTAINED IN THE UNIT VOLUME OF CEMENT, MORTAR OR GROUT. FOR A GIVEN QUANTITY OF CEMENT, IT IS THEREFORE OF THE GREATEST INTEREST TO INTRODUCE ONLY A MINIMAL QUANTITY OF WATER AT THE TIME OF APPLICATION. BUT THIS MINIMAL QUANTITY IS LIMITED BY THE NECESSITY OF MAINTAINING AN ADEQUATE FLUIDITY OF THE MIXTURE. DESPITE MODERN PROCEDURES OF APPLICATION, NOTABLY THE SYSTEMATIC UTILIZATION OF VIBRATION, THE QUANTITIES OF WATER USED ARE SEEN TO BE GENERALLY STILL TOO GREAT. THE L. C.P.C. STUDY SHOWS THAT THE USE, IN RELATIVELY SMALL QUANTITIES, OF RESINS OF THE EPOXY TYPE IN ACCORDANCE WITH A PROCEDURE HERE DESCRIBED MAKES POSSIBLE A SUBSTANTIAL REDUCTION IN WATER CONTENT WHILE STILL MAINTAINING SUFFICIENT FLUIDITY OF THE FRESH PRODUCTS. THE PHYSICAL AND MECHANICAL PROPERTIES OF CONCRETES, MORTARS AND GROUTS APPLIED BY THIS PROCESS ARE THEREBY GREATLY IMPROVED. /LCPC/A/RRL/
