Aggregates for Concrete

Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of

Gravel Driveway: Types of Gravel, Drainage Edging

Crushed stone driveways: Besides limestone, granite, gneiss, dolomite and trap rock are popular for driveways. The stone is screened and sorted for size; the angled rather than round edges cause the stones to support one another to create a stable base. The color of crushed stone for driveways varies widely, and they can be dusty like limestone.

Effects of crushed stone dust on some properties of concrete

Abstract. Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand. This dust is composed by particles which pass 75 μm BS sieve. Effects of dust content in aggregate on properties of fresh and hardened concrete are not known very well. An experimental study was undertaken to find out the effects of various proportions of dust content on properties of fresh concrete and hardened concrete.
