Quarry Dust Materials: Quarry dust has some potential as a fine aggregate substitute for river sand in the construction of concrete. It is essentially a by-product of stone crushers created during the coarse aggregate crushing and screening process. The compressive strength of the concrete is somewhat improved when quarry dust is used in place ...

This paper presents the latest studies on the use of eggshell powder in construction materials such as concrete, cement mortar, brick, alkali-activated binder and a soil stabilizer. ... Cement is a binder that is commonly used in construction. It is mixed with sand and crushed stone to produce concrete or with a fine aggregate to produce …

Similar results were observed when 0%-40% limestone powder was utilised to replace type 2 cement in grouts used to stabilise sand and low-plasticity clay.

The percentage passing 150 microns of manufactured sand is relaxed to 20% (while that of natural sand is limited to 10%). As per design and economics, crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season.

The granite-manufactured sand had a stone powder content of 12.02 %, an value of 4.85, and a fineness modulus of 2.79. The specific parameters before and after milling and the sample morphology are shown in Table 3 and Fig. 2, respectively.The coarse aggregates were 5–10 mm and 10–20 mm in size and were compounded in a 2:3 ratio.

rapid growth in construction activity, the available sources of natural sand are getting exhausted. Also, good quality sand may have to be transported from long distance, which adds to the cost of construction. In some cases, natural sand may not be of good quality. Therefore, it is necessary to replace natural sand in concrete by an alternate ...

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. Depending on the size of the holes in the screen, the texture of this stone dust can be …

Manufactured sand is featured by its irregular shape, rough surface, high elongated and flaky particles content, poor gradation and high stone powder (SP, particle size＜0.075 mm) content, which made it a lower quality succedaneum of natural sand (NS) and greatly restricted the engineering application of MS (Cepuritis et al., 2017; Hafid et al ...

The CDW head sample represents the aggregates after the second crushing stage at Urbem recycling plant (crushed < 19 mm).Around 50% of this product's weight is below 4.8 mm (sand fraction) and 6% is below 0.15 mm. Regarding just the fraction bellow 3 mm of head sample, named as CDW-sand, it has 15% of its weight below 0.15 mm.. …

Table 7 indicates that stone powder type D had the highest specific surface area, followed by stone powder type C, Tokuyama clay, stone powder type B, cement and Toyoura sand in that order. A higher specific surface area means that more stone powder particles were available for the same amount of cement-treated clay (20–75 µm) …
