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

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
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 ben ....etc
