    Abstract

    A study was conducted by the authors to assess the possibility of using sea dredged sand from Singapore in concrete construction. Various combinations comprising normal sand, washed and unwashed sea dredged sand, potable water and seawater for mixing were considered. The properties of concrete made with washed and unwashed sea dredged sand by using potable and seawater for mixing were evaluated and compared with those determined for concrete made by using normal sand and potable water. The study has shown very encouraging results. The authors report the details of this study and offer arguments based on their research in favor of using sea dredged sand as aggregate in making concrete.
