and environmental degradation associated with mining of gravel from deposits to replenish gravel lost on roadways. To minimize these concerns, unpaved or gravel roads may be upgraded by bituminous surfacing to quartzite, granite, pegmatite and other quartz-rich rocks. In Ghana, the gravels are limited mostly to the Eastern, Central, Volta
Quartzite aggregate samples obtained from the depth of mining. hand-quarry sources have about 75% of the constituent In Ghana, quartzite is the rock mass forming the row of particles having sizes that range between 20 and 50mm.
Keywords: Quartzite types, aggregate strength, quartz, concrete 1. Introduction Concrete production for construction purposes is an activity which goes on in almost every country. Concrete is a mixture of fine and coarse aggregates, an appropriate binder and water in specified ratios and is used for
The Mining industry of Ghana accounts for 5% of the country's GDP and minerals make up 37% of total exports, of which gold contributes over 90% of the total mineral exports. Thus, the main focus of Ghana's mining and minerals development industry remains focused on gold. Ghana is Africa's largest gold producer, producing 80.5 t in 2008.

The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other, resulting in very hard and dense quartzite. Relation to Mining Because it is so dense and resistant to both physical and chemical weathering, it is a poor bedrock on which to form soil.
The use of hand-quarried weathered quartzitic aggregates as the coarse component of concrete was investigated. Samples of hand-quarried quartzite aggregates exhibiting different degrees of weathering were evaluated in quality and their suitability as coarse component of concrete. The 7, 14, 28 and 56 day compressive strengths were obtained from 100mm concrete cube samples prepared with the
For the purpose of this work, three types of coarse aggregates, quartzite, granite, and river gravel, were used. The fine aggregate is normal sand obtained from a borrow pit.

Quartz is one of the most common minerals in the Earth’s crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO 2), having a specific crystalline form (hexagonal).It is found is all forms of rock: igneous, metamorphic and sedimentary.
Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite.
Quartzite solid mineral deposits in Nigeria, West Africa can be found in Ekiti, Taraba, Kogi, Kwara and Oyo states.
