FAQ's

Q: What is concrete ready mix?

A: Concrete ready mix, also known as ready-mixed concrete, is a pre-mixed blend of cement, aggregates (such as sand or gravel), water, and additives. It is produced in a batching plant and delivered to construction sites in a transit mixer truck.

Q: How is concrete ready mix different from on-site mixed concrete?

A: Concrete ready mix is prepared in a batching plant according to specific proportions and quality standards. On the other hand, on-site mixed concrete is prepared at the construction site using raw materials and mixed manually or with the help of a mobile mixer.

Q: Can concrete ready mix be customized for specific projects?

A: Yes, concrete ready mix can be customized for specific projects by adjusting the mix proportions, additives, and admixtures. This allows for the production of different types of concrete with desired characteristics, such as strength, durability, or workability.

Q: How is concrete ready mix transported to the construction site?

A: Concrete ready mix is transported to the construction site using transit mixer trucks. These trucks have rotating drums that keep the concrete in motion, preventing it from setting. The trucks are equipped with mechanisms to control the mixing speed and discharge the concrete at the desired location.

Q: What is the typical shelf life of concrete ready mix?

A: The shelf life of concrete ready mix is generally limited to 90 minutes to 2 hours, depending on various factors such as ambient temperature and the use of additives or retarders. After this time, the concrete starts to harden and becomes difficult to work with.

Q: Can additives be used in concrete ready mix?

A: Yes, additives can be used in concrete ready mix to modify its properties. Common additives include plasticizers (to improve workability), accelerators (to speed up the setting time), retarders (to delay the setting time), and air-entraining agents (to introduce tiny air bubbles for improved freeze-thaw resistance).

Conclusion:

Concrete ready mix offers numerous advantages in terms of consistency, quality, time and cost efficiency, convenience, and versatility. By understanding the composition, manufacturing process, and considerations associated with ready mix usage, construction professionals can make informed decisions that lead to successful projects. It is crucial to carefully select reliable suppliers, communicate project specifications, and implement proper on-site handling and quality control measures to ensure optimal results.
