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

Behavior of instrumented prestressed high performance concrete bridge girders
A comprehensive monitoring of the behavior of four prestressed high performance concrete (HPC) bridge
girders, with higher compressive strength, during construction and while in-service, is discussed in this article. The instrumentation and monitoring of a group of four girders during the process of casting operation, after construction and under the conditions and influences of traffic and thermal loads, as well as under controlled load conditions is done.Th ....etc

HIGH PERFORMANCE CONCRETE USING FUMED SILICA

INTRODUCTION
High performance concrete is a concrete having low water binder ratio. A value of 0.4 is suggested as boundary between usual concrete and high performance concrete.
It has high strength and durability. For high durability low permeability is required and to reduce permeability silica fume is used

IMPROVEMENT OF CONCRETE DURABILITY BY COMPLEX MINERAL SUPER-FINE POWDER



Introduction
Coal gangue is a rock included in the coal bed and a waste discharged during coal
mining and transportation as well as the most industrial waste discharged in China. It
is estimated , that the amount of gangue calculated as 15% of the coal output,
there would be 100 million ton increment annually. Most of the coal gangue is a clay
rock; its main mineral composition consists of clay min ....etc

High performance concrete bridges
introduction
HPC is made with some basic ingredients but has totally different microstructure than ordinary concrete
HPC is an engineered concrete obtained through a careful selection
The low water/binder ratio of HPC that is its universal characteristics
It has very dense microstructure having a very fine and more or less well connected capillary system
Dense microstructure of HPC makes the migration of aggressive environmental conditions.
