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

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 ...

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.

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.
