How to control wastage of concrete at site? While estimating quantity of concrete for particular structural work, we normally consider 3-5% as wastage. But wastage of concrete more than that can in

Achieving Durability of Concrete Structures: The durable concrete structures are to be conceptualised, specified, designed, contracted, constructed and maintained. To achieve the design life of the

Hot weather has a significant effect on all stages of concrete production and placement procedures such as increasing rate of hydration and movement of moisture from within and surface of the concr

In recent times, we have seen a drastic transition from brick masonry to concrete block masonry due to its numerous advantages such as fire resistance, good acoustic performance, cost-efficiency, a

High-strength concrete and high-performance concrete are not synonymous because strength and performance of concrete are different properties of concrete. High-strength concrete is defined based on

High range water reducing admixture reduces the quantity of mixing water required to produce concrete of a given consistency by 12 % or greater, as per ASTM C 494- C 494M. It is capable of producin

High performance lightweight concrete is produced by carefully mixing specified amount of cement, sand, lightweight aggregate, different pozzolans such as fly ash, silica fume, shale, metakaolin, c

High-performance concrete (HPC) is produced by careful selection and proportioning of its constituents namely cement, sand, gravel, cementitious materials such as fly ash; silica fume; and slag, an

There are several applications of high-performance concrete in the field of civil engineering due to its superior properties such as high strength and good durability. The high-performance concrete
