MECHANICAL AND DURABILITY PROPERTIES OF HYBRIDEFIBER REACTIVE POWDER ON CONCRETE
Main Article Content
Abstract
Adding fibres to concrete greatly increases the toughness of the material. The use of fibres also alters the behaviour of the fibre matrix composite after it has cracked, thereby improving its toughness Secondary cementing materials like Reactive Powder can be used to partially replace cement because of pozzolanic nature. Materials like quartz powder best suites to sand due to its physical and chemical properties, fineness etc. Also these materials are known to increase durability, resistance to sulphate attack . Our main aim is study the materials Reactive powder, Quartz powder, Silica Fume are best suitable for preparing durability of concrete for M30 Grade. In cement replaced by silica fume and quartz powder with various percentages like 5%, 10%, 15% and20%. And additional strength purpose using crimped steel fibres and poly propylene fires with various percentages like 0.5%, 1%, 1.5% and 2%. In this study mechanical properties like compressive strength, Split tensile strength and Durability properties like Acid attack test, Sulphate attack test, Alkalinity attack test, Rapid Chloride permeability test and Water permeability test and Young's modulus test can be accomplished. And the comparative study of normal concrete and fibres concrete.
