This scarcity has spurred the search for alternative fine aggregates with manufactured sand produced using crushers, which are emerging as a promising substitute. This artificial sand must adhere to the accepted gradation standards, as it can reduce the voids and cement consumption, enhancing the cost-effectiveness.
Crushed rock sand (CRS), industrial by-products (IBP) and recycled fine aggregates (RFA) are different types of alternative fine aggregates. The economic, sustainability and social benefits increases utilizing into concrete.
The use of industrial by-products as an alternative fine aggregate in concrete is a long-term, reasonable approach to excessive river mining and industrial by-product disposal. Although previous research on alternative fine aggregates is available, a complete assessment that considers many industrial by-products is lacking.
The most commonly used in construction is a fine aggregate from river sand or pit sand. Fine and coarse aggregates constitute about 75% of total concrete by volume. It is, therefore, essential to obtain right type and best quality aggregates at sites, because the aggregate forms the main components of the concrete mixture or mortar 3.
A comparative analysis of sand (conventional) and stone dust (alternative) as a fine aggregate was carried out through several tests for physical characteristics, petrographic and geochemical ...
Construction aggregates derived from primary resources either by crushing of sound rock masses (crushed stone aggregates) or from naturally occurring unbound clastic sediments (natural sand and gravel aggregates) make the most voluminous mineral raw material exploited by humans nowadays (Fookes 1991; Přikryl 2017).Extremely low …

Crushed rock sand (CRS), industrial by-products (IBP) and recycled fine aggregates (RFA) are different types of alternative fine aggregates. The economic, …
This study aimed to explore the possibility of utilizing crushed glass as an alternative fine aggregate for concrete by replacing concrete with crushed glass. Specifically, the study sought to assess whether there is a significant correlation between crushed glass volume in concrete and its compressive strength and also between sand volume in ...
On the shrinkage of concrete, the fine aggregate properties also have a significant impact. Types Of Fine Aggregate uses: In concrete or pavement construction usually, sand, crushed stone and crushed …
Aggregate materials like sand, gravel, and crushed stone occupy a substantial volume of concrete used in constructions. The demand for high quality aggregates that meet the specifications of civil engineers for construction activities is increasing year after year. A...
This paper includes the existing environmental problems due to continuous extraction of river sand, alternative sand types suggested in various studies, advantages and …

Thus, there is a need for river sand and aggregates alternatives in concrete, namely manufactured sand (m-sand) from primary solid rock materials and secondary waste materials. The focus in the present study for Vietnam was on m-sand sand as alternative for river sand, and different ashes as alternatives for cement in concrete.
Manufactured sand (M Sand), offshore sand, sea sand, quarry dust, and demolition waste have been identified as the most common substitutions for river sand.
of natural river sand and finding its alternatives, growth of the construction and infrastructure industry throughout the globe is demanding the need to examine the feasibility of using other alternatives such as fly ash–geopolymerization reactions to produce fine aggregates as an alternative to natural sand.
The utilization of sea sand as an alternative to fine aggregate in the manufacture of concrete is motivated by the availability of sea sand in nature in very large quantities.
The purpose of this study is to evaluate the possibility of using granulated pumice as an alternative to fine aggregate in production of lightweight cement mortar. The cement/pumice fine aggregate ...
The primary objective of the research is to evaluate the suitability of Ambo Sandstone Fine Aggregate (ASFA) as an alternative replacement of river sand in normal concrete production.
The purpose of this study is to evaluate the possibility of using granulated pumice as an alternative to fine aggregate in production of lightweight cement mortar. The cement/pumice fine aggregate ratio is 1:3 for pumice aggregate mortar. The water content is determined by flow table test. Compressive and flexural strength, freeze-thaw …
However, the extraction and consumption of natural aggregates, such as river sand and gravel, have negative impacts on the environment and human health. Therefore, there is a need to find alternative sources of aggregates that are more sustainable and eco-friendly.
1. Introduction. Rapid urbanization made concrete the most widely used construction material worldwide. As the major fine aggregate of commercial ready-mix concrete, the natural river sand resource is therefore depleting [1], [2].On the other hand, the fine fraction of the recycled concrete aggregate derived from construction and …
This paper helps in providing alternative sand to conventional river sand (fine aggregate) in concrete production. In desert region, dune sand are found deposited in large quantities due to strong and breezy wind peculiar to …
This study examines various alternatives to fine aggregate (conventional Sand) replacements (such as Waste Foundry Sand, Graphite Tailings, Low-Density …
Aggregate is an important part of the concrete and acts as an inert material in concrete. Coarse aggregates are uneven and granular materials such as gravel, sand, or crushed stone, and are utilized for making concrete.. As concrete demand and consumption increase rapidly demand of natural aggregate also rinsed.
This reinforces the feasibility of desert sand as a viable alternative to traditional fine aggregate in concrete production. Liu et al. [ 18 ] researched the pore structure and mechanical properties of concrete made from desert sand, specifically investigating the effects of exposure to high temperatures.
The purpose of this study is to evaluate the possibility of using granulated pumice as an alternative to fine aggregate in production of lightweight cement mortar.
In this study, effect of foundry sand as fine aggregate replacement on the compressive strength of concrete with a M30 mix proportion investigated at different limited curing periods (7 days, 14 days and 28 days). The percentage of foundry sand used for replacement were 10%, 20%, 30%, 40% and 50% by weight of fine aggregate.
