Concrete Mix Design: Understanding Aggregate - NPCA Aggregates with angular shapes typically have a higher percentage of void spacing between them and produce less workable concrete than rounded aggregate. Water demand is higher because of higher friction resistance and greater surface area-to- volume ratios, resulting in the need for more cement to maintain the desired water-cement ratio. How much Ballast do I need to Mix Concrete? Concrete is created using several ingredients. Coarse aggregate or "ballast" is a primary component. This is added to cement that binds the aggregate particles together. Water and any additional additives are also used to create the final mixture ready for pouring.    Read More

  • What Is the Formula for Concrete Mix? | Reference

    The formula for concrete mix is one part cement, two parts sand and three parts gravel or crushed stone. If hand mixing, it's inadvisable to exceed a water to cement ratio of 0.55, which translates to 55 pounds of water for every 100 pounds of cement. When mixing concrete, it's necessary to ensure that there is an adequate amount of aggregate.
