High Performance Concrete Topic

High-performance concrete (HPC) is concrete that has been designed to be more durable and, if necessary, stronger than conventional concrete. HPC mixtures are composed of essentially the same materials as conventional concrete mixtures, but the proportions are designed, or engineered, to provide the strength and durability needed for the structural and environmental requirements of the project.

Properties of Hardened Concrete; A Detailed Guide

As the concrete has completely set and hardens, some further shrinkage may result because of contraction of gel-structure due to further loss of moisture, or drying (against the term evaporation used in the first type of shrinkage). This kind of shrinkage is practically an essential and irreversible property of concrete.

What is Raft Foundation? Difference between Raft Foundations

Raft foundation is a thick concrete slab reinforced with steel which covers the entire contact area of the structure like a thick floor.

Weigh Batching vs Volume Batching

Batching by volume achieved by using a constructed gauge boxes (Farmas) for proportioning the materials according to various mix proportions and based on the quantity of material needed per batch. In small works gamellas are also used for batching. But it is not recommended for batching of concrete.

The importance of the water–cement and water–binder ratios

When batching concrete, each of its solid components is weighed; thus, it is common to express the w/c ratio as a mass ratio instead of a volumetric ratio. In this book, the symbols w/c and w/b will be used for the mass ratio, whereas W/C and W/B will be used for the volumetric ratios, according to American Concrete Institute (ACI) terminology.
