  • Experimental Study on Suitability of Sea Sand as Fine

    River sand has been the most popular choice for the fine aggregate component of concrete in the past, but overuse of the material has led to environmental concerns, the depleting of securable river sand deposits and a concomitant price increase in the material. Therefore, it is desirable to obtain cheap, environmentally friendly substitutes for river sand that is preferably sea sand. The Land

  • Use of sea-sand and seawater in concrete construction

    30.11.2017· The UK was the pioneer country to use desalted sea-sand as fine aggregate in concrete . In the 1960s, British experts conducted a series of studies on the use of sea-sand as a raw construction material,,,. Over 21 million tonnes of sea-sand and gravel was extracted annually around the coast of England and Wales from 2000 to 2004. On average, desalted marine aggregates accounted for approximately 17% of the total amount of fine aggregate and gravel used in concrete

  • What Is Fine Aggregate Types of Fine Aggregates

    What Is Fine Aggregate? Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼” or smaller. This product is often referred to as 1/4’” minus as it refers to the size, or grading, of this particular aggregate.
