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 specimen ....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

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

Abstract
This paper focuses on the experimental investigation carried out on high strength concrete reinforced with hybrid fibres (combination
of hooked steel and a non-metallic fibre) up to a volume fraction of 0.5%. The mechanical properties, namely, compressive strength, split
tensile strength, flexural strength and flexural toughness were studied for concrete prepared using different hybrid fibre combinations
steel polypropylene, steel polyester and steel glass. The flexural properties were studied using four point bending t ....etc
