The global consumption of river sand as a fine aggregate in the production of concrete and mortar is very high. Unfortunately, in the last 20 years, the obtainability of river sand is reducing and several countries have problems in supplying. One option to solve the scarcity of river sand is to use sea sand in the construction field. In the current paper, an attempt has …

This study gives a comparison on the relevant material properties of Sea Sand (SS), Desert Sand (DS) and River Sand (RS).Different fine aggregate materials (SS, DS and RS) were used in 10%, 20% ...

Sun et al. [81] studied the influence of three different types of fine aggregates, river sand, undisturbed sea sand and desalted sea sand, on the frost resistance of cement mortar. The results showed that the mass loss of SSC showed a linear growth with the increase of freeze–thaw cycles, and the frost resistance of SSC after desalting ...

The present paper provides comprehensive evaluation of utilization of sea sand in concrete and emphasises the need for further research on sea sand as fine aggregate in concrete. Key words: Sea ...

Fine aggregate, sea sand, minerals, concrete strength Abstract. Sand researches around the world are in continuous search for the alternatives of sand. Fine aggregate is an important constituent of concrete and is required in large quantities. Generally, river sand is used as fine aggregate.

Sea sand is abundantly available and shall be a potential resource capable of supplying fine aggregate for domestic constructions. It is also economical form of fine aggregate at coastal regions.

Fine aggregate is basically any normal sand particle that comes from the land through the mining process. Fine aggregates comprise regular sand or any squashed stone particles that are 1/4″ or smaller. This item is frequently alluded to as 1/4″ short as it alludes to the size, or evaluation, of this specific aggregate.

Unfortunately, the direct use of sea sand as fine aggregate of reinforced concrete is often limited by various standards in various countries around the world. Ref. [80], [81], [82] desalinated sea sand by using natural storage techniques, mechanical methods, fresh water flushing techniques, mixing techniques, corrosion inhibitors, and other ...

MS (figure 2), which was collected from Tiruchendur beach in Tamil Nadu, is used as a fine aggregate.To assess the chloride content, the chemical composition of MS is studied using an XRF test before and after washing. Table 2 gives the results of chemical composition [].Marine Sand's physical properties are also investigated (table 1).There is the presence of …

Sand is often utilized as a fine aggregate in concrete, contributing 22 to 62% of the total mass. The quantity and features of sand in concrete have an impact on its workability, mechanical characteristics, and durability. Effective replacements are needed as natural silica sand becomes scarcer. By incorporating these by-products into concrete, landfill discharge …

From the beginning of 1960s, researchers from the US and UK studied the effect of seawater and sea-sand used in concrete [4, 26, 33, 35], Griffin and Henry . This was followed by Japanese researchers who used desalted sea sand as one of the main sources of fine aggregate in concrete .

Therefore, the use of sea sand as fine aggregate to prepare geopolymer concrete is a potentially advantageous method [17]. The physical properties of several geopolymers and associated compressive strength are summarized in Table 1. Table 1. Summary of Previous evaluations of fly ash and GGBS based geopolymers.

In case of 80% replacement of sea sand as fine aggregate the Characteristic compressive strength is reduced by 49.37%. It is observed that for replacement of sea sand as fine aggregate in concrete compressive strength is reduced by 53.82%. Usage of Sea sand in concrete found there is a

2.2. Sea Sand Instead of Fine Aggregate Sea sand is sand taken from the shores of the beach, the shape of the grains are smooth and round due to friction with each other [9]. This sand is bad because it contains a lot of salt. This salt absorbs water content from the air and causes the sand to always be rather wet and

The partial replacement of sea sand as fine aggregate in concrete was used in gradually increasing proportion to make concrete blocks and then compression and tensile tests are done at 7, 14, 28 ...

Fine aggregate commonly known as sand is an inert material widely used for construction works. From concrete production to mortar, asphalt, and even t. ... Sea Sand: Derived from seashores, sea sand may contain salt and other impurities. It requires thorough washing before use in concrete due to the potential presence of chlorides, which can ...

The hardening process occurs because of the continuous chemical reaction between water and cement [7] [8]. 2.2. Sea Sand Instead of Fine Aggregate Sea sand is sand taken from the shores of the beach, the shape of the grains are smooth and round due to friction with each other [9].
