FUNDAMENTALS UNDERLYING SHRINKAGE IN CONCRETE - A REVIEW

SHRINKAGE IS FREQUENTLY RESPONSIBLE FOR CRACKING OF CONCRETE. THE PAPER REVIEWS THE PRESENT STATE OF KNOWLEDGE WITH REGARDS TO PRINCIPLES WITH GOVERN THE SHRINKAGE PHENOM- ENON IN CONCRETE. TOBERMORITE IS THE PRINCIPAL PRODUCT OF HYDRATED PORTLAND CEMENTS, AND IT IS GENERALLY THE MAJOR SOURCE OF DRYING SHRINKAGE IN HARDENED CONCRETE. CONSEQUENTLY, EXPLANATION OF DRYING SHRINKAGE IS BASED ON CRYSTALLOGRAPHIC STRUCTURE OF TOBERMORITE, NATURE OF WATER ASSOCIATED WITH TOBERMORITE, AND VOLUME CHANGES CORRESPONDING TO CHANGES IN THE ASSOCIATED WATER. THE INFLUENCE OF OTHER FACTORS SUCH AS CEMENT COMPOSITION, AGGREGATE CONTENT, MIX PROPORTION, AND CURING CONDITIONS IS ALSO BRIEFLY DISCUSSED. /RRL/A/
