aggregates Vasarhely and Bobet 2000 This research discusses cost evaluation in the total process of aggregate production from extraction through processing Classification of Aggregate According to Zongjin 2014 aggregates can be divided into several categories according to different criteria In accordance with size i
The high demands for crushed rocks as construction materials in the Cross River State and elsewhere in Nigeria have led to the establishment of many granite quarries by investors for the production of rock aggregates In southeastern Nigeria basement rocks are known to occur at Oban and Obudu regions Ekwueme 1988 1990 2003
The dominant rock for coarse aggregate production in Ethiopia is generally basalt while ignimbrite is most commonly used for masonry stone On the other hand the majority of sand is collected from When bond is good a crushed concrete specimen should contain some aggregate particles broken right through in addition to the more numerous
The granites are being quarried for aggregates marbles are powdered for cement production while migmatites and granite gneisses were mined for dimension results of Rock Strength MPA
The rock aggregates from Quarries A and B met all the physicomechanical requirements for use as aggregates for crushed rock subbase base and surface dressing for pavements
The materials used for this study were river aggregates crushed aggregates bitumen and produced asphalts obtained from the Natural and artificial sources Method standard stated BS 812 was used to sample the river aggregates from Kuta river in Niger State being a common alternative material for crushed aggregates
In this research grinding energy of selected rock samples collected from South West Nigeria was determined using comminution theory in order to evaluate suitability of rock for aggregate production
Khaloo 1995 investigated the use of crushed tile as a source of coarse aggregate in concrete The crushed tile had a lower density and a much higher water absorption value compared to those of natural crushed stones The resulting concrete made with 100% crushed tile as the coarse aggregate had a lower density and higher compressive 2%
In this work the properties of some basement rocks in Bansara area in the Nigerian sector of the Bamenda massif which determine their suitability for the production of aggregate for construction works were assessed to evaluate their performance as pavement materials The rock materials evaluated were from Biotite Granite Granite Gneiss Schist and
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 million tons while the total production was around 18 million tons leaving a supply difference of
