Effect of Boron Waste on Mechanical and Durability Properties of Concrete.

It was emphasized that 8% of the CO₂ emission that causes global warming occurs during cement production. In addition, the consumption of natural resources used in cement production increases due to the increase in cement demand with the widespread use of concreting. In this context, studies on alternative binders continue in order to reduce cement production and consumption. Today, besides the use of mineral additives such as blast furnace slag, fly ash and silica fume as binders in concrete mixtures, studies on the disposal and sustainability of other industrial wastes are continuing. One of the wastes generated in the industry is formed in boron plants. It is important to evaluate boron wastes especially in Turkey, which has significant boron reserves in the world. Studies on the use of boron wastes in concrete mixtures have recently become widespread. In this study, a comprehensive literature search was conducted on the effect of boron waste usage on the fresh state, mechanical, durability and radiation absorption properties of cementitious systems. In this context, with the increase in the use of boron waste and the increase in its usage rate, the radiation absorption properties of cementitious systems, their resistance to high temperatures and freeze-thaw have improved. However, with the addition of waste, the fresh water requirement and setting time of the mixtures increased. In terms of compressive strength, if the boron wastes in the mixtures exceed 10%, their compressive strength generally decreased. [ABSTRACT FROM AUTHOR]
