aggregates—sand, gravel, crushed stone, and aircooled blastfurnace slag—produce freshly mixed normalweight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 53) are used to produce structural lightweight concrete with a freshly mixed density
(1) The use of low addition levels of both fresh CKD and LKD as mineral filler in hot mix asphalt surface course mixes (approximately 5 percent by weight of aggregate) reportedly exhibit mix properties comparable to that of natural filler such as hydrated lime and stone dust. Gradation, organic impurities, and plasticity requirements normally associated with mineral filler specification requirements can .
b) Stone dust : Stone dust used in the laboratory investigations was procured from a local crushing plant. The specific gravity of stone dust was and fineness modulus was Coarse Aggregate a) Conventional Coarse Aggregate: Machine crushed granite obtained from a local
Stone dust is a byproduct of crushing rock for other uses. Many suppliers also provide delivery of the product, but may require an additional fee. When setting pavers to form a walk or patio, stone dust serves as an alternative to sand. The dust contains very fine particles so compacted stone dust sets up to form a waterproof barrier under the ...
Variation of compressive strength with water/cement ratio and laterite/quarry dust ratio for 1:1:2 Mix. Figure7 shows that for 1::3 mix, the optimum water/cement ratio is Laterite is known to absorb water which gives reason for the high water/cement ratio.
In the form of fine powder granite waste, the cement was replaced using 5%, 10% and 15% by weight in the concrete mixture. In addition, in the form of granules granite waste, the sand was replaced using 10%, % and 25% by weight.

Abstract: The present investigation aims at the study of properties of concrete in which stone dust is used as a partial replacement for coarse sand and tyrechips of size to 10 mm as partial replacement of coarse aggregate by weight. Keywords: Cement, Coarse sand, Coarse Aggregate, Stone Dust, Tyre Chips size to10mm
In this study overburnt brick aggregate (OBBA) and stone aggregate (SA) have been mixed in different ratios (by weight) such as 20 : 80, 40 : 60, 60 : 40, and 80 : 20, respectively. The laboratory results indicate that bituminous concrete, prepared by 20% brick aggregate and 80% stone aggregate, gives the highest Marshall stability.
Shanker and Ali(5) have studied engineering properties of rock flour and reported that the rock flour can be used as alternative material in place of sand in concrete based on grain size data. Nagaraj and Banu(9) have studied the effect of rock dust and pebble as aggregate in cement and concrete.

Engineering characteristics of crushed stone and coal ash mixture compaction piles. The test results indicated that the highest internal friction angles were obtained at an 80:20 mixing ratio of crushed stone and bottom ash. The internal friction angle declined when the mixing ratio of the bottom ash became greater than 20%.

In addition, the unit weight of calcitic marble powder (γ s = g/cm 3) and granite powder (γ s = g/cm 3) were similar. The higher unit weight of the dolomitic marble powder (γ s = g/cm 3) resulted in a higher unit weight for the soil sample stabilised with the dolomitic marble powder.
Physical properties are those that can be observed without changing the identity of the substance. The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties.
