M-Sand. Manufactured sand is an alternative for river sand. Due to the fast growing construction industry, the demand for sand has increased tremendously, causing deficiency of suitable river sand in most parts of the world. Due to the depletion of good quality river sand for the use of construction, the use of manufactured sand has been …

The compressive and flexural strengths of concrete made with enhanced sand gradation increased by 10–25% and 9–17%, respectively, for 28 MPa concrete compared to the control concrete. Cost analysis showed that 28 MPa concrete made with enhanced natural river sand gradation was 8.6% more economical than concrete made with coarse pit …
fine aggregate. . Hence to make use of these M-sand in the construction industry, a systematic study has to be carried out on the replacement with Natural River sand in making concrete. The raw material for M-sand production is the parent mass of rock. It is based on the parent rock that the chemical, mineral
The results indicated that the concrete containing bottom ash, as sand replacement, at levels of 50% and had compressive strengths about 80% and 60% of reference concrete, respectively. The weight loss of reference concrete surface by abrasion was 53% to 30% of weight loss of bottom ash concrete.

The appearance and particle size distribution of coal bottom ash is similar to that of river sand making it as an attractive replacement to river sand for the production of concrete [14], [19]. Wongsa et al [26] studied the properties of concrete by replacing river sand with bottom ash up to 50%.
Crushed rock sand has surfaced as a viable alternative to Natural River sand and is being now used commonly throughout the world as fine aggregate in concrete. It is manufactured by crushing the quarried stone to a size …
The research also revealed that there is possibility of replacing fine aggregate with quartz sand in the production of structural concrete. The mix proportion adopted was 1:1.7:3 as per 10262:2009. Compressive …
Geopolymerization of fly ash in 10 M NaOH and Na2SiO3: NaOH= 1.8:1 solution at 100°C for one hour produced geopolymer fly ash aggregate (GFAS) to produce an alternative replacement for river...
The analysis shows that it is more economical to produce grade 40 concrete with a combination of 80% sand plus 20% CGF as fine aggregate, using gravel as coarse aggregate, at a cost of N16, 602 per …
Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
In of the studies about this states that the mechanical properties of special concrete made with 30 per cent replacement of natural sand with washed bottom ash by weight has an optimum usage in concrete in order to get a favourable strength and good strength development pattern over the increment ages. Bottom ash Quarry dust
Concrete cube is cast to test the compression strength for M5 grade concrete (since it is for PPC). As a result, strength is obtained related to cube cast …
Concrete cube is cast to test the compression strength for M5 grade concrete (since it is for PPC). As a result, strength is obtained related to cube cast using river sand in concrete. Using this result, we have figured out that granite granules can also be a better replacement with sea sand.
The results from the study showed that when waste glass was used as a partial replacement for coarse aggregate, it caused a reduction in the slump, density, …
One batch of concrete was prepared using standard and conventional ingredients, and the remaining six batches were made using recycled coarse aggregate (RCA) in place of all natural coarse aggregate (NCA), all quarry dust (QD) in place of river sand, and varying quantities of metakaolin (0, 5, 10, 15, 20, and 25%) in …
Concrete mixes with three strengths of 21 MPa, 28 MPa, and 35 MPa were prepared by partially replacing natural river sand with quarry sand. Workability and hardened concrete properties were evaluated for all mixes, and cost analysis was performed for 28 MPa concrete. The results were compared with control concrete made with coarse pit sand.
Concrete by Partially replacing Coarse aggregate Using Coconut Shell 43 3. METHODOLOGY In this study, natural river sand and manufactured crushed sand as 50%-50% proportion will be used as fine aggregate which passes through a 4.75 mm sieve. The material used will be having maximum particle size of 4.75mm. It
So, there is a need to economize cement and river sand in concrete making. To the reduction of waste materials on earth land fields and in the search for alternative blinders that WGP is replaced partially by cement in concrete and M-sand is used in full replacement of river sand as fine aggregate.
