When stones are run through a crushing machine to make crushed stone, stone dust also forms. Its exact composition will depend on what kind of stone ran through the machine, such as granite or limestone. The machine has a screen that traps the larger crushed stone and lets the smaller material (or "screenings") fall through the screen.
The compressive strength of concrete from stone powder shows 14.76% higher value than that of the concrete made of normal sand. On the other hand, concrete from brick chip and stone powder produce higher compressive value from that of brick chip and normal sand concrete. Key words: Stone powder, concrete, mortar, concrete, compressive strength.

To minimize the CO 2 emission up to some extent; industrial by-products can be utilised in concrete as replacement of cement. The stone slurry powder from stone industries has been used as replacement of cement in the present study. Calcium nitrate (1%), triethanolamine (0.025% and 0.1%) as additive and stone slurry powder (5%, 7.5% and 10%) as ...
Replacing cement with stone powder not only improves the performance of manufactured sand and concrete but also reduces environmental pollution, which is important …
Therefore, replacing cement with stone powder to reduce CO 2 emissions during concrete production is an attractive alternative to sustainability. The use of high-strength concrete (HSC) appears to be another alternative since higher compressive strength results in lower CO 2 emissions per MPa. In this context, the objective of the present work ...

Stone powder increased the unconfined compression strength of cement-treated clay. The strength depended on the particle size of stone powder. The amount of cement used …
Felekoglu produced SCC with quarry lime stone powder as partial replacement of cement reported the substitution of materials reduced the strength when lime stone powder content is increased [8]. Demone et al. analyzed the SCC fresh properties with 16mm and 20mm size coarse aggregates along with the lime stone fillers concluded the robustness of ...
This observation suggests that the optimal amount of stone powder serves a dual function, acting as both an activator and filler within the concrete, ultimately enhancing the microstructure of the concrete. These findings highlight the beneficial role played by an appropriate quantity of stone powder in improving concrete quality.
Replacing cement with stone powder not only improves the performance of manufactured sand and concrete but also reduces environmental pollution, which is important for realizing sustainable development of the construction industry. In a study on changing the stone powder dosage, Wang et al. [3] found that limestone powder can have a better ...
