dc.description.abstract |
Usage of offshore sand as an alternative to inland river sand is beneficial due
to the various environmental impacts of river sand mining in Sri Lanka. However,
higher amount of chloride ions in the sea sand can corrode the reinforcements of the
concrete. Therefore it's necessary to identify suitable, low cost and efficient method to
remove cl* ions from the sea sand. In this study, three different salt removal techniques;
mechanical washing, natural washing and recently introduced grain to grain collision
were evaluated using samples from beach sand, river sand, offshore sand and old stock
piled offshore sand. Relative salt content and absolute cl* content were measured using
conductivity measurements and titration, respectively. Mean grain size and other
textural parameters were calculated using sieve analysis. Results indicate lOOg of sand
soaked in 200ml of water, required approximately 10 minuets to remove salt from sea
sand. Natural removal of chloride by rainwater shows one year of Monsoon rain is
more than sufficient to remove salt from even 10 m thick piles of sea sand. However,
grain to grain collision does not show significant capacity to remove salt. |
