Superplasticisers are high range water reducing admixtures..Admixture is defined as a material other than cement ,water and aggregate that is used as an ingredient of concrete and is added to the batch immediately before or during mixing. The development of superplasticisers is one the major break throughs in concrete technology, which will have a significant effect on the production and use of concrete in the next millennium. Superplasticisers have been greatly responsible for development of the following connects.
1) High performance connect ....etc

UTILIZATION OF PAPER INDUSTRY EFFLUENT AS WATER REDUCING AGENT IN CONCRETE


ABSTRACT


The present paper describes the utilization of paper industry effluent as water reducing agent in concrete for its effects on various properties like slump, setting time, compressive strength etc. The properties have been compared with commercially available water reducing agents like modified lignosulphonate (MLS) and sulphonated naphthalene formaldehyde condensate (SNF). It has been observed from studies ....etc

Abstract: Admixtures are ingredients other than water, aggregates, hydraulic cement, and fibers that are added to the concrete batch immediately before or during mixing, in nominal
quantities. A proper use of admixtures offers certain beneficial effects to concrete, including improved quality, acceleration or retardation of setting time, enhanced frost and
sulphate resistance, control of strength development, improved workability, and enhanced
finishability.

Admixtures vary widely in chemical composition, and many perform more than one f ....etc

Corrosion Of Reinforcement In Hvfa Concrete

Introduction
Corrosion of reinforcements has been one of the major challenges that the civil engineers have been facing. Corrosion leads to the formation of rust which results in the spalling of concrete which in turn leads to the exposure of rebars to the aggressive environment. This will accelerate the ill effects and ultimately leads to the break down of the structure. Corrosion mainly occurs in areas of aggressive environment such as coastal regions. It is very important that corrosion of rein ....etc

ABSTRACT

High Performance Concrete is that concrete which meets special performance and uniformity requirements that cannot always be achieved by conventional material, normal mixing, placing and curing practices.

Architects, engineers and constructors all over the world are finding that using HPC allows them to build more durable structures at comparable cost. HPC is being used for building in aggressive environments, marine structures, highway bridges and pavements, nuclear structures, tunnels, precast units.
