The durability of quarry rock dust concrete under sulphate and acid action is higher than the conventional concret. Similarly water Absorption found to be more in the concrete containing crusher dust 2 .
The theoretical failure load of the SU series for a concrete strength of 28. though the strength of concrete was about 17 percent higher. the mean value of failure load of the beams with crusher dust was only about 6 percent more than that of the beams with river MPa works out to be Failure Loads Table8 indicates the loads at ...
Use of Quarry Dust to Replace Sand in Concrete ... is obtained by crushing the stone boulders of size 100 to 150mm in the stone crushers. Then it is sieved and the particles passing through 20 mm and retained on 10mm sieve known as course aggregate. The particles passing through sieve are called
It was concluded that the concrete made with 20% replacement of sand by crusher dust and 20% replacement of broken stone by gravel gave better results in terms of strength and cost. It was also noted that up to 40% replacement of broken stone by gravel and 20% replacement of sand by crusher dust also gave better results than control concrete.
Oct 02, 2011· Compacted crusher dust or roadbase is perfectly adequate for a perimeter path – and if you mix cement in with it (14x20kg bags per cubic metre of roadbase/crusher dust makes a pretty good "concrete") and thoroughly compact it, it will draw in ground moisture and set hard anyway.
Utilization of Stone Dust as Fine Aggregate Replacement in Concrete Brajesh Kumar Suman ... by 22% with the use of crusher dust at 40% replacement of natural sand (Pofale et al 2013).The ... percentage of stone dust in concrete as shown in table 3. It indicates at a constant dose of super plasticizer (, at % by weight of cement) .
Effects of crusher dust content in aggregate on properties of fresh and hardened concrete are not very well known. On the other hand, it is known that short discrete fibers delay the propagation of microcracks and improve some properties of concrete.
