STUDY OF AND EXPERIMENTS ON LIQUIDS WHICH CAN SET INTO MEMBRANES FOR CURING CONCRETE

ESTUDIOS Y EXPERIENCIAS SOBRE COMPUESTOS LIQUIDOS CAPACES DE FORMAR MEMBRANAS PARA CURADO DEL HORMIGON.

Investigations have shown that wet curing, when carried out under ideal conditions, gives the highest mechanical strength, greatest durability, reduction in volume changes, and cracking. But ideal wet curing conditions are very rarely obtained on site. In practice high-quality, well-applied liquids, able to form waterproof membranes, enable satisfactory uniform results to be obtained. This report is divided as follows: 1) concrete curing. Definition; 2) need for curing (cement hydration reactions loss in water content and cracking, time when curing must start); 3) general methods for preventing the evaporation of the free water contained in concrete; 4) concrete temperature. Its influence on curing conditions and on cracking in structures; 5) curing of concrete structures by means of liquids forming a waterproof membrane (composition and types of liquid, their general characteristics, classification as a function of standard ASTM-C-309); 6) significance of the tests specified in standards to evaluate the quality of the liquids used; 7) conditions of application on the site; 8) main advantages of membrane curing. Precautions to be taken during application; 9) results of quality control tests carried out at the limit on liquid samples; 10) conclusions on test results; 11) bibliography. /TRRL/
