As the water to cement ratio increases, the strength of a concrete mix decreases. As the surface area of the aggregate increases the more water will be needed to maintain a given slump. As the air content increases, the strength of the concrete decreases. It's always about volume! • What is absolute volume? What is Absolute Volume? Unit Wt.
