Crusher Dust/Quarry Dust Byproducts of the crushing process in quarries crusher dust or quarry dust can also be used as a fine aggregate These materials are finely graded and can contribute to improving the workability of concrete Answer Fine aggregate is used in concrete to serve two purposes 1 Provides a filler for the spaces
The investigations indicate that stone crusher dust has a good potential as fine aggregate in concrete construction Crusher dust not only reduces the cost of construction but also helps reduce
Debieb and Kenai [] have stated that crushed bricks as fine and coarse aggregates are becoming a serious interest to civil engineers as their use significantly decreases the issue of waste storage and protects natural aggregate it is clear that using recycled construction materials as replacement material in concrete reduces the need for natural aggregates
CEMENT Pozolana Portland cement PPC confirming to IS 1489 1991 part 1was used in this study PPC is prepared by dry manufacturing process It is more workable and high durable It has high heat of hydration Physical properties of cement are shown in Table 1 2 FINE AGGREGATES Fine aggregate are basically sands
water ratio is required when making concrete Fine aggregate are basically sands won from the land or the marine environment Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a sieve Effective Utilization of Crusher Dust in Concrete Using Portland Pozzolana Cement
C S H gel binds these various elements such as coarse aggregate fine aggregate and any admixture if any having said that cement is the most valuable and prized component of concrete however manufacturing of concrete has its own disadvantage and un sustainable every kilogram of cement manufacturing cause 1 kg of greenhouse gas CO 2
Concrete mix The concrete mixes were prepared using all of the eight different sand samples and remaining variables as constant with the cement fine aggregate coarse aggregate ratio of 1 2 4 by weight respectively cement content of kg/m3 lb/ft3 and water to cement ratio of with constant slump value
