Gravel for Construction and Landscaping
Gravel + Coarse Aggregates Coarse aggregates contain individual particles greater than 4.75 mm (more than a fifth of an inch) in any given dimension. They most popularly come in the form of gravel, which is composed of crushed rock or waterworn stone — although recycled concrete is also used in many commercial applications.

Feasibility Study of Establishing a Granite Aggregate
Granite is a coarse-grained intrusive igneous rock composed primarily of light-coloured minerals. Crushed granites are small chips of granite, used as a base layer for paving. They are rock-aggregate used in building and general construction [2]. In Southwest-ern region of Nigeria, the estimated demand in 2008 for granite chipping was 24.2 million

ENGINEERING CHARACTERISTICS OF WIDELY USED COARSE
Pakistan has vast potential of concrete aggregates due to having numerous mountainous ranges. However, the properties of these aggregates are yet to be explored as scant research has been carried out in this area. In this study, an experimental approach was adopted to compare the engineering properties of widely used coarse aggregates in Pakistan.
