EFFECT OF MIXING AND CURING TEMPERATURE ON CONCRETE STRENGTH

COMPREHENSIVE STUDY WAS MADE OF COMPRESSIVE AND FLEXURAL STRENGTHS PRODUCED BY DIFFERENT TYPES OF PORTLAND CEMENT USED IN CONCRETES MIXED, PLACED, AND CURED AT VARIOUS TEMPERATURES BETWEEN 25 F AND 120 F. TESTS INDICATE THAT THERE IS A TEMPERATURE DURING THE EARLY LIFE OF CONCRETE WHICH IS CONSIDERED OPTIMUM WITH REGARD TO STRENGTH AT LATER AGES. EFFECT OF CALCIUM CHLORIDE ON STRENGTH AT VARIOUS TEMPERATURES OF MIXING, PLACING, AND CURING IS REPORTED. EFFECT OF CEMENT TEMPERATURE WAS FOUND UNIMPORTANT, EXCEPT AS IT AFFECTED CONCRETE TEMPERATURE AFTER MIXING. MORE AIR-ENTRAINING AGENT WAS REQUIRED FOR A GIVEN AIR CONTENT AS CONCRETE TEMPERATURE INCREASED AND SLUMP DECREASED. /PCA/
