Effect of Accelerated Curing on Mechanical Properties of Binary and Ternary Blend Concrete

Abstract

Conventional concrete is being successfully utilized and has some drawbacks in terms of shear cracking due to high shrinkage, time of hydration, intervals in construction because of hydration of concrete, low tensile strength, emission of carbon dioxide and consumption of natural resources. Therefore, finding alternative materials and technique to reduce these issues becomes a great concern that ensure timely construction of concrete structures without compromising the strength of concrete. Accelerated curing technique is used for the time saving in construction and fly ash and bagasse ash is used for lesser consumption of natural resources and sustainable concrete construction. Locally available Waste materials are good option for conservation of resources and development of eco-friendly concrete.  For this purpose, twenty mixes of binary and ternary blend concrete were formed incorporating different replacement percentages of fly ash and Bagasse ash. All of these mixes were cured under normal curing condition and accelerated curing condition and found out the effect of curing regime on mechanical properties (compressive, tensile, flexure) on binary and ternary concrete. All the mixes showed good response to accelerated curing and achieved rapid strength compared to normal curing condition. All the concrete mixes achieved approximately 70% of their strength in just 28.5hr.
