What is concrete? Hagen Harker, president of Mid-States Concrete Industries, hosts conversations and demonstrations to explain the process of producing precast concrete in a multi-part vlog. During this presentation, engineers, project designers and production teams will discuss concepts to installation of precast elements. This in-depth look at the production of precast concrete exhibits how it contributes to green building practices. As explained by technicians, the low water-cement ratios possible with precast concrete mean it can be extremely durable. As demonstrated, precast concrete is factory-made, there is little waste created in the plant by employing exact-batching technologies and it reduces onsite construction waste and debris as well as construction indoor air quality concerns. Locally-sourced materials reduce early-stage life-cycle costs and product durability optimizes material use over the life of the building.
