The effect of maximum size of aggregate on concrete strength

A. As the nominal maximum size of the aggregate is increased, the amount of water needed for the same workability is reduced. At the same cementitious material content, strength is therefore greater because the w/cm is lower. But in the high-strength range, over 40 MPa (5800 psi), higher compressive strengths are usually obtained at a given w ...

Maximum Aggregate Size Effect on Frost Resistance of Concrete - American Concrete

Maximum size of aggregate was shown to have a great effect on frost resistance. For example, the 1/4 in. maximum aggregate size specimens showed expansions during freezing, only when the water-cement ratio was as high as 0.60, while 3/4 in. maximum aggregate specimens showed expansions at a water-cement ratio as low as 0.45.
