Thus, partial replacement of fine aggregate is vital in construction industries. Researcher and Engineers have come out with their own ideas to decrease or fully replace the use of river sand and use recent innovations such as M-Sand (manufactured sand), robot silica or sand, stone crusher dust, filtered sand, treated and sieved silt

Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand. Design mix of M25grade concrete with ...
CHAPTER 3 LITERATURE REVIEW. 18.8% greater compressive strength than conventional concrete when compared to 2.5 % and 1.5% of the silica fume. Average increase in compressive strength of concrete was found to be 11%, 12%, 18.8% and 5% for partial replacement of natural sand by M-Sand with 10 %, 30 %, 50% and 70%. Th.
The optimum percentage replacement of sand with fine glass aggregate was determined to be 20%. By using low -cost and environmental friendly building materials from industrial waste, a sustainable concrete can be produced. Keywords – Artificial sand, waste glass powder, fine aggregate replacement, compressive strength, flexural strength. I.

Experiments are carried out on different compression and flexural tests for each model of M20, M30, and M40. The graphs in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 indicates the value of compressive strength vs. % of Crush dust for 7 and 28 days. In order to express the available set of data in the form of equations, regression analysis has …

At least four manufactured sand gradations from each crusher dust were produced and tested. Also the 0/4 mm fractions of the crusher dusts (unprocessed) were included for comparison. Sea dredged natural sand complying with BS EN 12620:2002 was used as the control fine aggregate. Table 2 shows the notation used in this paper for all …
Coal bottom ash can not only be used as a fine aggregate but also as a partial cement replacement in the production of concrete. 3) Concrete incorporating coal bottom ash would be lighter in weight depending upon its proportion used. 4) Water absorption of coal bottom ash is higher than the sand.
The experiments were conducted on M20 and M30 concrete grade with 450 specimens. Slump cone, compaction factor and vee-bee time tests were conducted to determine workability. Results obtained showed that as replacement of natural sand by manufactured sand is increased, there is a decrease in the workability.
The compressive strength of cubes at 28 day curing for control mixture of 1:3:6 at 0% partial replacement of river sand with quarry dust was 12.6N/mm2 but compressive strengths of 21.5 N/mm2 and ...

This study reviews the fine aggregate (conventional Sand) replacements (such as Waste Foundry Sand, Graphite Tailings, Low-Density Polyethylene, Ceramic …
The research covered determining the effects of natural sand replacement with manufactured sand of C-25 concrete properties. This experimental study only limited to 0%, 10%, 20%, 40%, 60% and of replacement. In this experimental study, only some engineering properties of aggregates, slump
can be replaced by cement with crushed sand gives better compressive strength and flexural strength than cement and natural sand in concrete. Gopireddy Madan and G. Vimalanandan (2019) In this analysis, GGBS used as a partial replacement of cement, crusher dust as a partial replacement of FA, SSW as a partial replacement of CA.

This study reviews the various replacements for sand such as such as degraded marine, walnut shells, waste foundry sand, etc., in the production of concrete and also the use of …
The replacement of sand with stone dust at various ratios in medium-grade concrete showed an increase of up to 40 and 29% in compressive and up to 53 and 32% in flexural strengths for 7- and 28 ...
Quarry sand – Each crusher unit produces between 20 and 25 percent of its total output as quarry dust waste. If compressive strength is a concern, replacing sand with quarry dust should ideally range from 55% to 75%. He goes on to say that sand replacement is possible if fly ash another industrial waste is added. Foundry sand –
Literature review. Numerous studies on the use of granite waste as a partial replacement for cement or river sand in concrete and mortars have been conducted. Celik and Marar [1] replaced natural sand up to 30% with crusher dust in concrete. The maximum increase in compressive strength was observed at 10% crusher dust content.
Stone dust or quarry dust is a waste material obtained from crusher plants. It has potential to be used as partial replacement of natural stream sand in concrete. Use of stone …
