Advantages of Ready Mixed Concrete

Concrete that is delivered from a central facility in batches rather than freshly mixed on the construction site is referred to as ready-mixed. Every lot of pre-mixed concrete is created specifically for the contractor’s needs and supplied to him or her in a foam state, usually in the cylindrical vehicles commonly referred to as “cement mixers.”

In 1909, a horse-drawn blender that blended concrete as it drove to the construction using paddles propelled by the cart’s wheels was the first to provide concrete. Stephen Stepanian from Columbus, Ohiocreated the self-discharging automated transit mixer in 1916, which was the predecessor to the ready-mixed concrete truck we are all familiar with today. A deterioration in motor truck quality during the 1920s prevented the creation of superior ready-mixed vehicles. Easy Mix Sales companies were able to expand the volume of their mixing drums in order to fulfil the tremendous demand for concrete caused by World War II because larger trucks and better engines were made available in the 1940s.

Ready-mixed concrete is particularly helpful when pouring concrete in small amounts or on a sporadic timetable. Furthermore, ready-mixed concrete is ideal for large projects where space for a mixing plant or material stockpiles is limited. Three categories can be used to classify ready-mixed concrete. Materials that have been batch-mixed at a centralised factory are used to create concrete that has been transit-mixed, also known as truck-mixed. The mixing of concrete is frequently finalised at the job site after being partially mixed while in transit. Concrete can be mixed right before being poured at the construction site thanks to transit-mixing, which keeps the water from contaminating the cement and aggregates. Through the use of this technique, the issues of early hardening and slump erosion that are brought on by probable delays in the transportation or installation of centrally mixed concrete are avoided. Concrete may also be moved farther from the plant to building sites thanks to transit-mixing. However, a drawback of transit-mixed concrete is that its truck capacity is less than that of a similar vehicle carrying central-mixed concrete.

Shrink-mixed concrete is utilised to increase the truck’s carrying capacity while keeping the advantages of transit-mixed concrete. To minimise or decrease the amount of the mixture, concrete is partially blended at the plant before finishing mixing in transit or on the construction site.Once it reaches the construction site, ready-mixed concrete is frequently blended to ensure that the right slump is achieved. Conversely, freshly mixed concrete typically takes longer to firm up than re-mixed concrete. Materials, such as water and different types of admixtures, are routinely added to the concrete at the building site after it has been batch-produced to ensure that the required properties are reached before installation.

Concrete ready-mix can be replaced by a volumetric mobile mixer. This method is a cross between traditional on-site mixing and ready-mixed concrete. The volumetric mobile mixer is a vehicle that holds water and the ingredients for making concrete, which is then blended on the truck at the construction site to produce and transport concrete in the precise quantity required. On-truck mixing at the project site eliminates ready-mix concrete’s drawbacks, such as delays that could render the pre-mixed concrete useless.
