The phrase "aggregates replacement" is correct and usable in written English.
It can be used in contexts related to construction, materials science, or data management, where the term refers to substituting one type of aggregate with another.
Example: "The project requires aggregates replacement to improve the overall strength of the concrete mix."
Alternatives: "aggregate substitution" or "replacement of aggregates."
Various mortar and concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mixture) to 100% as fine aggregates replacement.
From this result, it was concluded that waste PET aggregates replacement with conventional aggregate in the mixture showed better insulation properties (i.e. lower thermal coefficient).
In this study optimum crumb rubber aggregates replacement percentage in SCC and optimum crumb rubber aggregates size in SCC have been presented and also optimal mix design of SCRC will be assessed to optimise fresh and hardened properties.
Composition and mix design influence on the concrete were studied in mixes ranging from 0.45 to 0.60 w/c ratios, with 0%, 20 %, 50 % and 100coarse aggregates replacement.
The results showed that considering mechanical properties, the 100% natural coarse aggregates' replacement would be possible when RCA were produced from original concrete with a minimum compressive strength of 60 MPa.
These eco-aggregates, obtained by mixing industrial by-products or wastes such as ashes with carbon dioxide (CO2), have some characteristics which make them useful in the field of construction materials such as natural aggregates replacement in concrete or mortar.
Lumachelle stones, which are produced by marine sediments widely available in most coastal areas, can be considered as one of the aggregates replacements in roller compacted concrete (RCC).
Mageswari and Vidivelli [8] study the use of SDA as fine aggregate replacement in concrete by replacing sand with 5 30 % of SDA and found similar results as obtained with sand.
To evaluate the practical application of waste oyster shells (WOS) as controlled low-strength materials (CLSM), using a reference sample and four fine aggregate replacement 5%, 10 %, 15 and 20%and20sand, and the cement was replaced by 20% fly ash of the materials WOSe tesand.
Twenty-one RACFST specimens with different aggregate replacement ratios were prepared for the tests.
The study suggests that the optimal RAP BOF aggregate replacement content is 20%.
