Effect of type of coarse aggregate on the strength ...

2018-5-1  However, strength of one type of concrete to another vary only in the range 2.5–7.4% indicating that type of aggregate has not shown much impact on compressive strength of Normal Strength Concrete. It is due to the fact that the aggregate is not the strength limiting factor as it is stronger than cement matrix and transition zone.

Abstract An attempt has been made in the present work to study the effect of type of coarse aggregate on the strength properties and fracture energy of M30, M50 and M80 grade of concretes. The aggregate used in this study includes Grey Granite (GG), Anorthosite (AS) Charnockite (CK) Limestone, (LS) and Gneiss (GS). The result shows that the strength of concrete is greatly influenced by the ...

Effect of Different Types of Coarse Aggregates on Strength ...

Different types of coarse aggregates have distinguished petrological, petrographical and mineralogical and local characteristics, thus, their effects on concrete strength development are quite significant, various and unpredictable. So, the laboratory investigation on the concrete mixtures using local aggregates becomes very necessary before used in engineering practice.
