  • Aggregate - Pavement InteractiveTraduire cette page

    Aggregate " is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete). By volume, aggregate generally accounts for 92 to 96 percent of HMA and about 70 to 80 percent of portland cement concrete.

  • The Suitability Of Limestone Aggregates For Use In ...Traduire cette page

    Because limestone aggregate is normally comprised of crushed fragments, the better surface texture and higher angularity that obtains lead to good bond with the cement and good particle interlock, both of which help in achieving good compressive strength properties. Our general experience with concrete made with limestone aggregates has indicated that somewhat lower cement contents are ...

  • Geology: Physical Characteristics Of LimestoneTraduire cette page

    04/02/2011 · Limestone is an aggregate. The main constituent is calcium carbonate, or calcite. Shells, bones, and other calcium-laden materials sink to the bottom of the ocean and settle on top of each other. Years of pressure from the buildup of material and the water pushing down on the layers causes the bottom material to solidify and form limestone.
