202211 · Manufactured sand known as M sand is common and it is used as fines in the development of concrete composites [3]. They are produced artificially by crushing hard granite stones into smaller grains and it is washed to remove minute particles and graded as fine aggregate. M sand particles are mostly angular and rough in texture and preferred in ...

view more202443 · Due to the impact of economic and social development on the environment, there is an increasing demand for manufactured sand to replace natural sand as fine aggregate for concrete. At the same time, the effect of admixtures on the rheological properties and compressive strength of concrete is crucial in civil engineering …
view moreThe ease of installation makes this manufactured stone veneer a favorite of masons as well as do-it-yourselfers. Also known as castle rock or castle stone. Hackett stone is a stone veneer product measuring 1" to 1.5" thick and therefore thinner than traditional stone siding for easier, lighter handling.

The concrete slump was designed as 180 ± 10 mm, meeting the pumping requirements. The effects of the workability, …
view moreThis study aims to examine four machine learning (ML)-based models for their potential to estimate the splitting tensile strength (STS) of manufactured sand concrete (MSC). The ML models were trained and tested based on 310 experimental data points. Stone nanopowder content (SNPC), curing age (CA), and water-to-cement (W/C) ratio were also studied for …

The use of manufactured sands, a man-made fine aggregate product from crusher fines, as a partial replacement or 100% replacement of fine aggregate in a concrete mixture has become more common [16], [20], [21].Manufactured sands are essentially a waste product from producing coarse aggregate and so it is …
view more2023128 · Our previous research [36] found that GP partially replacing granite manufactured sand (GMS) can reduce the porosity of manufactured sand mortar (MSM). However, the synergistic effect of inert GP and active mineral admixture (GGBFS, FA and MK) in MSM is an issue worthy of further exploration, especially regarding their impact on …
