·Two 10 mm × 10 mm tungsten carbide Drickamer style anvils with 20° tapers truncated to 4 mm faces are inserted into the ends of the containment ring and fit flush to the BE gasket The sample is a precision ground 1 mm diameter × mm thick disk of Columbia River basalt glass that is inserted into a mm cylindrical hole in the BE
Essential Points Most of the aggregates possess a relative density within with a similar particle density of about 2400 2900 Kg/m 3 150 181 lb/ft 3 ; Hereabouts for coarse aggregates the standard test process has been described in ASTM C 127 AASHTO and for fine aggregates the standard test practice has been described in ASTM C 128
· Physical Properties of Coarse Aggregates Gradation Particle size distribution of aggregates significantly affect the packing density and void content in concrete According to Neville [] the gradation of aggregate has the main role in establishing the workability of can influence workability segregation bleeding
·was concluded that the rock aggregate angularity is associated with the order of Bulk density ρ g/cm 3 coarse grain classes above 20 mm basalt 1 w as characterized by lower
·Basalt extrusive igneous volcanic rock that is low in silica content dark in color and comparatively rich in iron and magnesium Basalts may be broadly classified on a chemical and petrographic basis into two main groups the tholeiitic and the alkali basalts Learn more about basalt in this article
·The specific density of basalt ranges between and kg/cm 3 The density of the basalt aggregate is higher than the limestone The water absorption of the basalts ranges between % and % Table 3 Table 3 Physical and mechanical properties of aggregates Aggregate Property Basalt Limestone Specific gravity Fine

·Factors Affecting Aggregate Density Several factors influence the density of aggregate including 1 Type of Rock Different types of rocks vary in their density and so; For example granite as well as basalt has high denseness unlike limestone or sandstone 2 Moisture Content water content influences the apparent density of aggregate since
