Riccelli-Northern's New On-Site Ready-Mix Batch Plant

Apr 23, 2021 · "The concrete is fresher, the mix is more consistent. It's stronger due to water cement ratio, consistent finishability, and yards per hour are more consistent than transit mixed. Plus, on site plants don't have to deal with pending traffic issues," says Mark McCraith, Riccelli-Northern's Production Manager of Ready Mix Operations.

CONCRETE - Boral

cement determines, to a large extent, how strong the hardened concrete will be. Most concretes are designed with a certain cement content and enough water to make the mass workable. Providing workability is adequate, reducing.the mixing water content makes the batch stronger and the addition of water makes the batch weaker. 2.
