Ready mix concrete is prepared concrete that is made in a single batch plant at the production site, usually according to a pre-designed precast concrete mix model. Ready mix concrete is typically delivered in two methods. The first method is to wet mix which is mixed at the plant and the other is dry mix. Both types of concrete have different attributes and require different mixes.
Wet ready mix concrete will generally contain cement dust, sand and water and is usually expressed in cubic yards or cubic meters. The wet concrete mixture is then mixed with pressurized water in a concrete plant that is well designed for mixing concrete. At the same time, ready mix concrete may also be mixed in-house in smaller batches using a truck-mounted mixer.
Dry ready mix concrete contains cement dust only and is expressed in cubic meters. In some cases, dry concrete may be mixed directly in the plant or may be mixed at a plant-house site prior to arriving at the construction site. The cement dust content in ready-mixed concrete varies greatly. Usually, dry concrete mixes can be purchased from cement suppliers for express packages at a fixed price.
Concrete batching plants are used for producing concrete on a large scale. Generally, ready mixes are produced in large amounts when construction work is taking place and the quantities required for a given project are great. Top professionals have a keen understanding of what your projects concrete needs will be. A top rated concrete contractor in Bakersfield www.bakersfieldconcretecontractors.com has experience this for all their stamped concrete and commercial concrete projects. Once the project is completed, concrete batching plants either disconnect from the system or remove materials from the area and dispose of them on the construction site. Usually, they are run on diesel generators and operate on battery power, but electricity can also be sourced from utility lines.
The second method used by ready mix concrete manufacturers and batching plants is for ready-to-pour concrete which is then transported to the construction site. The transport trucks containing raw materials for the concrete are placed on the ground parallel to the roads where concrete will be poured. Once concrete has been poured, the container carrying the concrete then comes into contact with the loose gravel and soil, and the cement hardens as it absorbs the moisture in the air and becomes denser.
Ready mix concrete designs are developed for different types of applications where fine aggregate or rock salt is used as an input. Ready mixes are made by various manufacturers based on specifications provided by the client. Some concrete companies create ready mixes by combining fine aggregate rock salt with water, gravel, sand and natural cement. Others combine cement and rock salt to create cement paste ready mixes for use in making pavers, tiles, slabs and stones. A variety of other concrete mixes are available for ready-to pour (RTR) applications and are designed for use in concrete batching plants or in making batch concrete on-site.
In addition to ready mixes, there are other benefits of volumetric mixing. It can produce concrete structures with greater density and greater load-bearing capabilities. Volumetric mixers are cost-effective when compared to traditional on-site mixing methods such as batching or roller mixing. They also reduce labor costs as well as costs associated with disposing of waste. It is also easier to use volumetric concrete mixer equipment.
Concrete is mixed in a series of containers using a large vertical mixer that combines and pulleys the ingredients for the final product. The containers contain coarse rock gravel and fine aggregate dust, which are held together with a network of wires. These containers are then transported to the construction site where the ready mix concrete mixes are then poured and set into place on the surface or sub-surface.
