11;Coarse fraction of CRD, generally, used as crushed sand or manufactured sand contains much fines or fillers when compared to natural sand. CRD is chemically inert, but can
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
Test results indicate that crushed stone dust waste can be used effectively to replace natural sand in concrete. Concrete made this replacement attain the same compressive strength,

31;In Fig. 5, the fineness modulus of the different types of concrete varies very little for w/c ratios between 0.36 and 0.45. It observed that fineness modulus increases and varies
With help of stone crusher large boulders of 100 to 150 mm size is reduced in smaller sizes. Crushed stone is separated Physical properties like specific gravity, fineness modulus etc.

Crusher Dust Content: The nominal particle size of artificial sand is less than 0.08mm, and its mineral composition has the same particle content as the processed parent rock. Fine
quarries while the stone crushes, stone crusher dust that is abundantly available from crusher units at a low-priced in many areas, maintain practical option for concrete river sand. Table-3.3
The quarry rock dust was obtained from local crusher at Kariapatti, Virudunagar District. The specific with a modulus of fineness = 2.20; Specific gravity 2.677,
NOTE* Weight lower than 150 micron is not considered in calculation :- Fineness modules (F.M.) = 2.45. Q.3) A sieve analysis was carried out for 5 kg aggregate in the laboratory with

• Very fine material such as silt, clay, or dust of fracture can increase the water demand in concrete • Fines limit is 3% in ASTM C 33 for concrete subject to abrasion • Manufactured
201611;Optimization results 5.5.1. Optimized fineness modulus The optimized sand samples were evaluated for their fineness modulus. The results are tabulated in Table 3. It
reported that beams with stone crusher dust and sand both developed same ultimate strength[4].Sahu, et al replaced Table 11: Mortar strength incorporating Quarry dust of

Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75 Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in
Stone dust is well appropriate in terms of strength and economy over normal sand for medium grade concrete (Mahzuz et al 2011). 40 percent fine aggregate can be effectively replaced
