cement-stabilized soil, and cement-stabilized aggre- gate base are sometimes used. Cement-modified soil can be a hardened, unhardened or semihardened mixture of soil and cement. When relatively small quantities of portland cement and moisture are added to a soil material, the chemical and physical properties of that soil material are improved.
cement plant contacts, regulatory agency contacts, or AFR supplier contacts. These discussions led to the identification of "emerging issues," concerning alternative fuels that are either in use or being investigated by the cement plants. For these additional
that the concrete aggregate to be used for a project is potentially reactive with alkalies in the cement, a low-alkali cement will be used. b. High-early-strength cement. Concrete using Type III cement achieves about 75 percent of its design strength within approximately 3 days.

4.2 Central-Plant-Mixed Method 4.2.1 Mixing.Soil-cement shall be central-plant mixed in an approved continuous-flow or batch-type pugmill, or rotary-drum mixer. The plant shall be equipped with metering and feeding devices that will add the soil, cement, and water into the mixer in the speci-fied quantities.
Truck Mixed Concrete ± Truck mixing is a process by which previously proportioned concrete materials from a batch plant are charged into a mixer truck for mixing and delivery to the job site. Central Mixed Concrete ± Concrete mixed completely in a stationary mixer and then transferred to another piece of equipment for delivery.

plant money in both repair costs and lost business due to downtime. The way to keep your batch plant in good working condition is to set up and follow a regular maintenance schedule. Because batch plants come in many different styles with var-ious layouts and types of equipment, there is no one maintenance plan that can be used at every plant.
