Treating and Recycling Concrete Process Water - Precast concrete
The water sources and target solids content for the actual batching water will all have to be taken into consideration when designing a process water recycling system. Wilbert Precast Inc. in Spokane, Wash., set out to minimize the amount of waste and costs associated with cleaning and coring operations.
PDF Sustainability and Precast Concrete
water. 3. Is precast concrete different from other types of concrete?

Production of Precast Concrete - Sustainable Precast
Forms Precast forms are normally made of either steel or plywood. A large number of castings in forms is typical in the production of precast concrete elements in plants with savings of raw materials. Plywood form use is limited to about 20 to 50 castings depending upon the complexity, maintenance and shape of the form.
Precast Concrete Sustainability | Nitterhouse Concrete
Precast concrete can have a relatively low water-cement ratio of between 0.36 and 0.38. This low ratio means the weight of the water compared to the weight of the cement is less than in a typical mix - it also increases durability. After treating it, you can often recycle water used for making concrete.
