Abstract
Shape and grading of aggregates can influence concrete workability. The volumes of water for well graded and poorly
graded vary along with cementations materials are commonly increased to adjust. The basic purpose of this paper is to
show that by properly selection of aggregates and changing mixture proportions, the proportion of cementations materials
provided for workability can be minimized while achieving suitable workability and strength properties. In this research
study of strength properties of high Performance concrete is achieved by using diverse characteristics of aggregate and
the results obtained from laboratory testing of concrete having varying aggregate characteristics. By the purpose of this
work, two types of coarse aggregates have been used. The fine aggregate is normal sand obtained from a locally available
(BHOLARI /JAMSHORO AREA Latitude: 25.317. Longitude: 68.217 AND 25.416868, longitude is 68.274307.
Jamshoro, Pakistan) initial laboratory investigation was conducted to obtain the suitability of using the aggregates for
construction work. The various tests conducted include sieve analysis, bulk density, and specific gravity. ASTM mix
design was adopted for this work and mix compositions were calculated by absolute volume method. For each and every
type of coarse aggregate 25 numbers cubes (150x150x150mm) were cast to allow the compressive strength to be
monitored at. 56 days. Test result reveals that concrete made from a type aggregate has higher compressive strength.
