Concrete Mix Design - Introduction

2021-1-1  INTRODUCTION. ACI 211.1-91, Reapproved 2009, states: "Concrete is composed principally of aggregates, Portland cement, and water, and many contain other cementitious materials and/or chemical admixtures. It will contain some amount of entrapped air and may also contain purposely entrained air obtained by use of admixture or air-entraining cement.

Water/Cement Ratio - an overview ScienceDirect Topics

The cement content of concrete is of less significance than the w/c ratio for structural durability, provided the mix is of adequate workability. The cement content for a hydropower structure is normally between 220 and 375 kg m −3. Concrete mix design is decided by two factors: strength and durability.
