INFLUENCE OF COARSE AGGREGATE SHAPE ON THE

2008-3-14  The PI value of coarse aggregate significantly affected the engineering properties of a HMA mix. The particle shape determined how aggregate was packed into a dense configuration and also determined the internal resistance of a mix. Of the four particle shapes evaluated, the cubical aggregate demonstrated the best rutting resistance.

Effects of shape and size of aggregates in concrete

How does the shape and size of coarse aggregates affect the properties of concrete? A. Aggregate shape and surface texture influence the properties of freshly mixed concrete more than the properties of hardened concrete. Rough-textured, angular, and elongated particles require more water to produce workable concrete than smooth, rounded compact ...

The effect of aggregate shape on concrete strength

A. Particle shape principally affects the w/cm by its effect on water demand and amount of paste required for workability of a given mixture. Also, the bond with the cement paste may be weakened due to the accumulation of bleed water under the relatively large surface areas of flat particles of aggregate.
