Potential alkali-reactivity of granite aggregates in the Bukit Lagong area, Selangor, Peninsular Malaysia

The Bukit Lagong area is the most important aggregate supply centre in Selangor. Geological studies were carried out in four quarries in the Bukit Lagong area and samples were subjected to petrographic examination and accelerated expansion tests to assess the potential alkali-aggregate reactivity of...
