Effect of Type and Volume Fraction of Aggregate on the ...

Tasdemir et al., 1995). The effect of the maximum size of aggregate on both the fracture energy and the brittleness may be important, if the crack surface roughness induces aggregate interlock, and as a result, concrete absorbs more energy (Karihaloo, 1995). It was recently indicated that as the maximum size of aggregate increases, the

Does Aggregate Size Affect Concrete Shrinkage?| Concrete ...

A.: Cement paste shrinks and most aggregates don't, so increasing the aggregate content (reducing the paste content) reduces shrinkage. To produce a workable concrete, a small maximum-size aggregate such as pea gravel requires a higher sand content than does a larger maximum-size aggregate.

The Effect of Aggregate Size on The Strength of Concrete

This study was conducted to determine the effect of concrete strength using coarse aggregate 10mm, 20mm and fine aggregate (sand mining) 3mm, randomly purchased from suppliers.
