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.

HIGH DEFINITION OPTICAL DISC TECHNOLOGY
Current Media Format
CD’s
Consist of pits and lands stamped out in a spiral pattern on the disc.
A laser then reads the pits and lands.
The change from a pit to a land or a land to a pit indicates a one while no change indicates a zero.
Current Media Format (Cont.)
CD-RW’s
Consist of a metal phase change alloy which when heated can be to change to reflectivity
CD-R’s
Consist of a dye that is applied to the disc.
When a writing laser is shined it change ....etc

HIGH PERFORMANCE CONCRETE (HPC) – A SOLUTION TO VARIOUS PROBLEMS

Shibu O.K

INTRODUCTION


High performance concrete (HPC) can be considered as a logical development of cement concrete in which the ingredients are proportioned and selected to contribute efficiency to various properties of cement concrete in fresh as well as hardened states.
High performance concrete (HPC) is defined as a concrete mixture which posses high workability, high strength, high modulus of elasticity, high dim ....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.T ....etc

INTRODUCTION-CONCRETE
 The word concrete comes from the Latin word concretus (meaning compact or condensed), the past participle of concresco, from com- (together) and cresco (to grow).
 Concrete is a construction material composed of cement ,coarse aggregate , plus a fine aggregate such as sand, water, and chemical admixtures.
ORIGIN OF HPC AND UHPC
 Environmental aspects
 The necessity to decrease the amount of CO2 in atmosphere.
 Replacement o ....etc
