Title

THE EFFECT OF CASTING TEMPERATURE ON SOME MECHANICAL PROPERTIES AND DURABILITY OF DRY PRESSED PRECAST CONCRETE KERBS

Pages

  119-130

Abstract

 Hot or cold weather condition affects the quality of the concrete in different ways, which one of them is increase or decrease in the INITIAL TEMPERATURE of the concrete. In this study, the impact of the INITIAL TEMPERATURE of the concrete on its quality in concrete kerbs made by dry pressing method with Portland cement is examined. Concretes with similar mix designs and INITIAL TEMPERATUREs of 17, 25, 29, and 39oC were made and cured in the standard laboratory condition. Then, in different ages some tests were carried out on them. The test results showed that the temperature of the concrete during placement is a parameter that affects the strength and durability properties of the concrete. For the INITIAL TEMPERATURE of 39oC, the quality of the concrete had a significant decrease. For the temperature range in this study, the INITIAL TEMPERATURE of 25oC resulted in the highest quality of the concrete. In the 7 and 42 days of age, the concrete with 25oC INITIAL TEMPERATURE obtained the highest COMPRESSIVE STRENGTH and the lowest WATER ABSORPTION. The highest ELECTRICAL RESISTIVITY in high ages was related to the concrete with 17oC INITIAL TEMPERATURE.
