Use of sea-sand and seawater in concrete construction ...

30/11/2017  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 .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 . Fig. 2 illustrates the situations of sea-sand ...

Existing studies have also shown that the use of sea-sand and seawater may have a significant effect on chloride-induced steel corrosion but has only a negligible effect on the carbonation process of concrete. Strong evidence exists that a combination of mineral admixtures for the concrete and reinforcement with fiber reinforced polymer (FRP) can effectively solve the durability problem ...

The rate of consumption of concrete has grown significantly over the years, becoming one of the most fundamental construction materials. This growth has depleted natural river sand and freshwater sources. The use of sea sand and seawater in concrete can provide sustainability to natural resources, while improving the mechanical properties of concrete. The corrosion of steel-reinforcement is ...

11/10/2018  We do not use use sea sand in construction due to following reasons. Sea sand tends to very fine and rounded, Smooth rounded particles would offer less resistance to rearrangement than angular or elongated particles with rough surfaces. In sea water, chloride is present which will cause corrosion of steel and iron which ultimately leads to reducing carrying capacity of steel and iron, so

Despite the practical problems of application, the use of post-construction surface-applied impregnations, such as silanes, siloxanes, etc., are helpful, especially for protection of pre-cast elements if sea-barged at early-age when they are particularly vulnerable to chloride contamination (see “c” below). By creating a hydrophobic zone in the outer millimetre or two of the all-important ...

Feasibility of Sea-Sand Sea-Water Concrete

Desalting of sea-sand and sea water leads to extra construction cost. So in this project we adopted the usage of sea-sand and sea water without desalting and to study its effect on compressive strength of concrete. Direct use of sea-sand and sea-water in concrete productions is particularly implemented for coastal and marine projects. II. OBJECTIVES • To study the effects of using sea-sand ...
