EFFECT OF CALCIUM CHLORIDE ON THE WATER REQUIREMENTS, SPECIFIC WEIGHTS AND COMPRESSIVE STRENGTHS OF CONCRETES MADE WITH PLAIN AND TREATED CEMENTS

SLUMP AND FLOW TESTS WERE MADE ON CONCRETES USING A PORTLAND CEMENT, A WIDE RANGE OF WATER-CEMENT RATIOS, AND TWO CEMENT FACTORS. COMPARATIVE TESTS WERE MADE ON CONCRETES CONTAINING TWO PERCENT COMMERCIAL CALCIUM CHLORIDE. CALCIUM CHLORIDE INCREASED THE WORKABILITY OF ALL CONCRETES TESTED, BEING SLIGHTLY MORE EFFECTIVE ON THE RICHER MIX IN THE RANGE OF SLUMP OF TWO TO SIX INCHES. WATER REQUIREMENT, COMPRESSIVE STRENGTH AND SPECIFIC WEIGHT TESTS WERE ALSO MADE ON CONCRETES OF CONSTANT SLUMP USING FOUR PLAIN CEMENTS AND FOUR CEMENTS CONTAINING AN INTERGROUND AIR-ENTRAINING AGENT. COMPARATIVE TESTS WERE MADE WITH TWO PERCENT CALCIUM CHLORIDE. COMPARED TO THE PLAIN CONCRETES, THE CONCRETES MADE WITH TREATED CEMENTS REQUIRED FROM 0 TO 2% LESS MIXING WATER AND HAD LOWER SPECIFIC WEIGHTS, AND IN MOST CASES HAD LOWER COMPRESSIVE STRENGTHS; THE ADDITION OF CALCIUM CHLORIDE TO THE VINSOL RESIN CEMENT CONCRETES DECREASED THE REQUIRED WATER AND INCREASED THE EARLY STRENGTHS AND THE SPECIFIC WEIGHTS. /AUTHOR/
