Investigation of compressive strength of ordinary concrete produced by industrial waste ash as a partial replacement of cement

Due to the expansion of urbanization and the increase in the amount of waste, one of waste disposal ways is to burn it in incinerator plants. On the other hand, the disposal of ash resulting from these wastes is one of the concerns of these plants. In this study, laboratory experiments were carried out to produce concrete incorporating ashes from industrial waste incinerated in the SAVEH waste technology complex as a partial replacement of the cement. In this research, the effects of adding these industrial waste ashes on the compressive strength of ordinary concrete were investigated. Concrete mixing design was performed according to national concrete mixing plan of Iran. Also, the ash contents incorporated into concrete are 0%, 10%, 20% and 30% of cement. The results show that as the ash content increases, the compressive strength of the concrete decreases, but the compressive strength obtained is still acceptable for the construction of concretes requiring less compressive strength, such as filler concrete or lightweight concrete in the building flooring. On the other hand, the use of this industrial waste ash incorporated into the concrete as a partial replacement of cement not only eliminates the concern of the incinerator plants to dispose this pollution, but also reduces the cement consumption and consequently reduces the greenhouse gases comes from the cement production.
