Abstract
The use of salty water for production of cement-based materials is one of the most efficient strategies to solve freshwater shortage problems in desert areas. The purpose of this paper is to investigate the effects of salty water from oil industry on fresh and hardened properties of the cement mortar. Semi-adiabatic calorimetry was used to study changes to cement reaction due to salt amendments. Incorporating salty water reduced the workability, slightly increased the wet density and no considerable effect on the air content compared to the control. Furthermore, salty water accelerated the hydration reactions, reduced setting time and enhanced the compressive strength at early ages, but later the enhancement decreased with curing time. It was apparent that the degree of impact depended on salinity level and ionic composition of the salty water.
