Answer: I'm not an authority on this subject, but here are some thoughts. That depends upon what the quarry dust is. If it has minerals that will react with the cement you could get a faster or slower set time. Also, since quarry dust is quite fine, you should have a denser concrete. Higher densi...

and autoclave blocks. Use of quarry dust as fine aggregate in concrete draws serious attention of researchers and investigators. Cement bricks are conventionally produced by using cement and fine aggregates in 1:6 mix these bricks also be produced by using wastes generated by stone crushers, quarry and saw dust from wood industry. Two

This study investigates the use of Saw Dust Ash (SDA) as partial replacement for ordinary Portland cement (OPC) in sandcrete blocks. Some units of sandcrete hollow blocks were produced by partially replacing the cement content with 5% to 25% by weight of SDA, using vibrating block moulding machine. Sandcrete blocks without SDA serve as the control.

The grading requirements used were based on specification. In terms of Saw Dust Ash (SDA), the filler CIDA replacement rates were 4.87% and 2.74% of SDA from the total aggregate weight of the mix (1200g). The replaced saw dust ash weights were calculated such that equal volumes of saw dust ash and stone dust will be subjected to the replacement.

The saw dust collected was sundried for 5 days to aid the burning process. The saw dust samples collected were burnt into ashes by open burning. The ash was then ground after cooling. Sawdust ash obtained is sieved through IS sieve of 300 micron. The specific gravity of saw dust ash obtained was 2.16. Fig 1: Saw dust ash (SDA)

Concrete is made up of cement, aggregates, sand, and water. The paste is made up of a mixture of Portland cement and water. Thus, concrete can be referred to as a mixture of paste, sand, and aggregates. Sometimes aggregates are replaced by rock. Cement paste coats the surface of the fine and coarse aggregates.

at 10% sawdust replacement, production costs and weight reduced by 3% and 10% respectively.
