grading for enhancing the performance of the material, has been recognized as a suitable substitute for river sand. The performance of using manufactured sand (M-Sand) as fine aggregates with comparison to river sand and CRF in the production of concrete and mortar has been widely studied for years.
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.
It can be inferred from the study that using quarry waste as a full river sand substitute and fly ash as a partial cement substitute in masonry blocks is a cost-effective and sustainable method. ... Cleaner production of concrete by using industrial by-products as fine aggregate: A sustainable solution to excessive river sand mining. Journal of ...
Workable, environmentally friendly, sustainable sand concrete was reviewed to replace river sand for concrete production. The river ecology and the biological balance will be preserved with the help of the carefully chosen sustainable sand. A systematic literature review (SLR) methodology was employed to extract the data.
It is not as coarse as concrete sand and can create a more workable and smoother concrete mix. River Sand: ... Sustainable or "green" concrete involves the use of recycled materials as partial substitutes for cement, sand, and aggregates. Fly ash, recycled glass, and crushed recycled concrete can be used to replace some of the sand and ...
Concrete Production. River sand is a key ingredient in concrete production, serving as a fine aggregate that binds with cement, water, and other additives to form a solid and durable construction material. ... Bottom ash, a byproduct of coal combustion in thermal power plants, can be processed and used as a substitute for river sand in certain ...
River sand, which is the natural choice of the construction industry, has become scarce due to its overexploitation and increasing environmental concerns. …
Fingerprint Dive into the research topics of 'Review and exploration of river sand substitutes for concrete production in Asian countries'. Together they form a unique fingerprint.
River sand, which is the natural choice of the construction industry, has become scarce due to its overexploitation and increasing environmental concerns. There is a strong need for research on river sand substitutes for concrete production and cement sand mortar production.
PDF | On May 6, 2018, Shivang Jayswal and others published Assessment of M-sand as potential substitute of natural river sand in concrete | Find, read and cite all the research you need on ...
In the meantime, the river sand acquired from waterway beds has been utilized primarily in the process of fine aggregate in the production of concrete. Because the supply of River sand is insufficient and its continuous supply is uncertain, use of Manufactured Sand (M-Sand) and Quarry Dust Sand as a substitute for
Abstract--The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a by-product from the crushing process
This study investigates the feasibility of using induction furnace slag as a substitute for river sand/manufactured sand (M-sand) in the production of concrete.
The Sea Sand was partially replaced with the River Sand (10% SS and 90% RS) mortar blocks were cast and similarly for desert sand (10% DS and 90% RS). For each …
Evidently, utilizing seawater and sea sand to produce concrete is an inevitable choice for alleviating the depletion of river sand resources and developing sustainable materials and construction.
options to river sand in concrete production in Vietnam using lab tests of concrete specimens manufactured from alternative materials and supporting LCA analysis as a response to current river ...
Manufactured sand (M Sand), offshore sand, sea sand, quarry dust, and demolition waste have been identified as the most common substitutions for river sand.
River Sand or the Bajri we refer to the sand that is used for construction purposes. Today it is the most required material. ... 1.5 million of C&D waste if recycled can significantly substitute the demand for natural sand in Delhi. Recycled sand and aggregate from C&D waste are said to have 10-15 percent lesser strength than normal …
Request PDF | Alternative fine aggregates in production of sustainable concrete- A review | Construction sector is mainly liable for waning of natural resources and environmental imbalances due to ...
The main aim of the study is to determine the degree to which dredged offshore sand can be used as a substitute for river sand by testing its physical, chemical, and structural characteristics.
High quality concrete mixture can only be produced with a proper choice of fine sand with requisite fineness module. The natural river sand is the cheapest option due to the ease …
This study assesses the feasibility of reusing tailings from a gold mining area in southern Ecuador in concrete block (CB) manufacturing. For this purpose, physical, chemical, and mineralogical analyses were performed to characterize the tailings. Furthermore, the tailing samples were subjected to the European Standard EN 12457-2 …
