The lack of river sand has led to the use of sea-sand and crushed stone fines in many countries, with the use of sea-sand in the UK being an example [4]. More than 90% of the world's dredged sea-sand has been used as a raw material in the construction industry, with over 45% of the dredged sea-sand being used as fine aggregate for concrete [5].

Fine aggregates: The fine aggregates used in the experiment include sea sand (SS) and river sand (RS). Sea sand was purchased from the Panyu Port No. 2 sand field, while river sand was purchased from the Langyu sand field. Their respective performance indicators are listed in Table 1. Both sea sand and river sand were used in their natural ...

Furthermore, the article includes a meta-analysis of data from tests assessing the strength and fresh properties of SW-SS concretes, in published articles. Also, the effects of salts from seawater, sea sand, and coral aggregates, on the long-term durability of seawater-mixed and sea sand (SW-SS) concretes, are critically reviewed.

The mining of sand and gravel in the sea is generally more expensive than on land, which is why, from a global perspective, deposits on land or in rivers are usually preferred. The impacts on the affected environments are enormous. River beds are deepened, which increases the current speed, causing bank areas to be washed away and bridge ...
