Behaviour of fibre reinforced self compacting concrete with granite waste and flyash

Abstract

Concrete is a most important and major construction material used newlinethroughout the world which creates many problems when not properly designed newlineand handled. The process of casting requires external energy for compacting the newlineconcrete. Concrete construction practice has shown that for on-site casting, newlinevibration is not always carried out effectively as it should be. It leads to low newlinequality end products. Self Compacting Concrete (SCC) can be placed and newlinecompacted under its own weight with little or no vibration and without newlinesegregation or bleeding. SCC is used to facilitate and ensure proper filling and newlinegood structural performance in restricted areas and heavily reinforced structural newlinemembers.Fibre Reinforced Self Compacting Concrete (FRSCC) is a highperformance newlinebuilding material that combines positive aspects of fresh properties newlineof SCC with improved characteristics of hardened concrete as a result of fibre newlineaddition. In recent decades, environmental considerations have become a major newlineconcern and efforts to reuse waste materials have been undertaken. The main newlineaim of sustainable development is to reduce the usage of natural resources by newlineproper reusing and recycling.In India, the state of TamilNadu alone produces more than 40 % of Granite Sawing Waste (GSW) which is resulting from cutting and polishing newlineprocess. This process results in a mixture of water and fine particles which after newlinedrying becomes a potential problem to the environment. This powder initiates newlinehealth problems in that locality. It needs proper disposal methods. The FRSCC newlinerequires fine filler materials to increase the powder content. The GSW which newlinecauses environmental problems can be used as a filler material in FRSCC newline newline
