THE ACTION OF VARIOUS SUBSTANCES ON CONCRETE

A REVISED TABLE IS PRESENTED, BASED ON THE LIST OF SUBSTANCES AND THEIR DEGREE OF HARMFULNESS. THE AGGRESSIVENESS OF VARIUS SUBSTANCES IN RELATION TO CONCRETE IS SUBJECT TO THE FOLLOWING GENERAL RULES: (1). ALL SUBSTANCES WHICH HAVE AN ACID REACTION MAY BE AGGRESSIVE. (2). ALL SULPHATES (SALTS OF SULPHURIC ACID) ATTACK CONCRETE. ALL SUBSTANCES CONTAINING SULPHUR ARESUSPECT IN THIS CONNECTION. (3). IN MANY CASES, CHEMICAL ATTACK CAN ONLY OCCUR IN THE PRESENCE OF MOISTURE. CONCRETE CAN BE PROTECTED EFFICIENTLY BY: (1). USE OF IMPERVIOUS CONCRETE, WITH A HARD AND WATERPROOF SURFACE (WELL-COMPACTED CONCRETE HAVING A WATER-CEMENT RATIO LOWER THAN 0.5). (2). SUITABLE PROTECTIVE MEASURES, SUCH AS PENETRATION TREATMENT, SURFACE DRESSING, SURFACINGS. /LCPC/RRL/
