Prediction of Some Properties of Retempered Concrete in Hot Weather

Abstract

This paper present statistical study to proposed empirical equations to predicting some properties of the fresh concrete (additional water for first and second retempering, final slump and dry unit weight), also some properties of the hardened concrete (compressive, flexural, split tensile strength and modulus of elasticity) depending on the simple properties of the retempered concrete mix (water cement ratio, temperature, air content, humidity, mix proportion and unit weight). Theoretical results obtained from these proposed equations found to be in good agreement with the experimental data found in literature. *Corresponding author: Ayad Zeki Saber Agha, Department of Civil Engineering, Erbil Technical Engineering College, Erbil Polytechnic University, Erbil-44002, Iraq, Tel: 009647704454107; E-mail: agha_ayad@epu.edu.krd Received December 02, 2017; Accepted October 18, 2018; Published October 24, 2018 Citation: Rashid MHF, Agha AZS (2018) Prediction of Some Properties of Retempered Concrete in Hot Weather.
