CONTROL OF SHRINKAGE CRACKING IN END RESTRAINED REINFORCED CONCRETE WALLS

Through this study, it has been endeavored to find out the final cracking pattern of shrinkage cracking in the walls of base and ends restraint an d with different (L/H) ratios to predict the suitable position of horizontal reinforcement to be effective as a means of limiting the width of cracks due to restrained shrinkage. In this study reduced scale o f reinforced mortar walls were used. Many characteristics of reinforced walls were measured such as restrained wall movements, crack spacing, crack width, crack lengths, drying conditions, different length to height ratios and their relationships after an exposure period of drying shrinkage. These walls were exposed to drying shrinkage through a period of three months in Winter and two months in Summer.
