ABSTRACT

Objective:
• To study the effect of fibres on the strength and behaviour of ultra high performance concrete (UHPC)wall panels under one way and two way in plane action.


Methodology:
The UHPC mix already developed (taken from literature) studied in detail with regard to its fresh and hardened properties and durability. Wall panels of size 750x750x35 mm are to be cast with different aspect ratio and volume fraction of fibres for testing under one way in plane action and two way in plane action. The speci ....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.

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

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

Abstract
This study aims to determine the influence of the content of water and cement, water–binder ratio, and
the replacement of fly ash and silica fume on the durability of high performance concrete (HPC) by using
artificial neural networks (ANNs). To achieve this, an ANNs model is developed to predict the durability of
high performance concrete which is expressed in terms of chloride ions permeability in accordance with
ASTM C1202-97 or AASHTO T277. The model is developed, trained and tested by using 86 dat ....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
