Suitability of Beach Sand as Fine Aggregate for Concrete

Abstract

Literature on the use of sea sand as a replacement of fine aggregate has been studied in the present work. This Suitability Of Beach Sand As Fine Aggregate For Concrete paper presents as partial and complete replacement of fine aggregates the design of concrete mixes made with sea sand.

Concrete is the world’s most widely used man-made product and is second only to water as the most widely used substance in the world. Because of the large amount of production, it is important to define the impact of concrete on global ecology.

This means that in addition to 1,5 billion tons of cement, the concrete industry consumes 9 billion tons of sand and rock each year, along with one billion tons of mixing water.

One of the major challenges, with the environmental awareness is exhaustion of river sand resources due to massive consumption. Economic development is bound to be affected if adequate and reliable sand resources can not be found soon. Uncomfortable transportation is increasing the cost of river sand resources.

River sand disadvantages: it is more expensive. Price fluctuations are greater depending on the presence of rain and floods. In the future may not be abundant due to over-exploitation.

Conclusion

For large-scale production, an offshore washing plant can be established. By mechanical washing, combined with the use of warm water, the chloride content can be removed to make de-salting more effective.
