What are the Factors Affecting Concrete Pumpability?

Pumpable concrete is a type of concrete transferred to a considerable height through pipes and used when a significant amount of concrete is required to be placed. The pumpability of concrete is influenced by several factors like cementitious materials, aggregate characteristics, admixtures, and batching and mixing of concrete constituents. Various cementitious materials such as fly …

Ready Mixed Concrete - Types and Advantages - The Constructor

Ready mix concrete is a special concrete mixer used for mass concrete construction with great quality control. Ready Mixed Concrete is a tailor – made concrete that is manufactured in a factory or within a batching plant based on the standard required specifications. The prepared concrete mixed is then taken to the work site within transit mixers mounted over a truck.

Ready Mix Concrete - Structural Guide

Nov 10, 2020 · Ready-mix concrete is the type of concrete mix used in construction mostly. Mixing of aggregates (coarse and fine aggregates), cement, water, and admixtures are done to an engineered mix in the batching plant to make ready mix concrete. After mixing, the mix becomes concrete and it delivered to the site by a truck mixture that maintains the
