Effects of Local Chemical Mineralogy On the Long Term Durability Of Reinforced Concrete Structures - Effects Of Calcium Carbonate- An Indian Perspective Using XRF

Abstract

Analyses of chemical constituents in sand were undertaken after these sand samples were collected from different sources, including river sand and manufactured sand from all over India, ensuring a fair representation. Indian subcontinent is home to 20% of the worlds' population. X-Ray Fluorescence (XRF) results along with data from X-Ray diffraction suggested that Indian sand is not necessarily pure silica based sand but all most always has calcium carbonate as a constituent.
