The effects of mixing temperature on concrete strength

Abstract

It is well documented that concrete casting temperature can affect both the development of strength and its ultimate value. This documentation however is not of recent origin and never had a local orientation. Although the test parameters were not solely related to local conditions, these can be easily interpolated since tests covered a whole range of temperatures. The objective of this study is to investigate the effects of casting temperature for fresh concrete on the surface finish achieved, density, and later strength variations. Therefore five temperature ranges were chosen and the strengths achieved at three, seven, and twenty eight days were compared. The experimental study also highlighted the influence which the mixing temperature has on the slump.
