Effect of varying water temperature on concrete properties
Abstract: The aim of this paper is to determine the effects of mixing-water temperature on the compressive strength, workability and water absorption rate of concrete. Locally available materials were used. Compression tests results showed that the 7 days value of 19.52N/mm2 at 35°C was higher than the value of 9.96N/mm2 at 5°C. The 28th day results for compression test also showed similar trend. The workability of the concrete decreased as the …
