2018-6-1  1. Introduction. Concrete is known as one of the most highly consumed construction materials. The primary ingredients of a concrete mixture are cement, aggregates (coarse and fine), water and admixtures (Mindess et al., 2003; National Ready Mixed Concrete Association (NRMCA), 2012).Among the aforementioned components, aggregate takes up about 70% to 80% of concrete’s volume.

Ingress of NaCl in concrete with alkali reactive

2016-1-4  Enhanced damage due to the alkali–silica reaction (ASR) in concrete exposed to deicing salt (NaCl) is usually attributed to binding of chloride ions in the hydration products of cement. To balance charge, OH− ions are released into the concrete pore solution which increases alkalinity. However, during NaCl ingress a decrease in the OH− concentration of the concrete pore solution due to
