The influence of oleic acid on the hydration and mechanical properties of portland cement

Abstract

To investigate the effects of OA on the portland cement using oleic acid (OA) as grinding aid and the effects of OA on the portland cement, we characterized the different perfermances of the cement, discussed the characteristics of properties. The results reveal that the OA can reduce the water requirement of normal consistency. With the content of OA added, setting time was extended. The OA can significantly improve the rheological properties of cement-based materials, while the compressive strength decreases.
