Abstract
The objective of this report is to assess the effects of using olive oil mill wastewater (OMW) and cheese whey on the production of concrete chemical admixture. Wastewater samples were taken locally from two factories in Izmir. Concrete chemical admixture combinations (waste water, polycarboxylate, molasses, defoamer, biocide and water) at different ratios were generated with statistical experimental design methods and the effects of some parameters, such as level of chloride (%), solid content (%), pH, density (gr/cm3), were investigated. Furthermore, concrete tests were performed to identify slump (cm) and strength (kgf/cm2) changes. The results showed that the addition of OMW and cheese whey up to 9.42 % (wt) and 12.51 % (wt), respectively can be potential admixture for concrete preparation, without loss of performance.
