Experimental Studies On Compressive Strength Characteristics Of High Strength Concrete Using Recycled Aggregate And Ggbs, Silica Fume

摘要

The present investigations are getting considerable attention under sustainable development now-a-days. The use of Recycled Aggregate (RA) from construction and wastes is showing prospective application in construction as alternative to primary (natural) aggregates. It conserves natural resources and decrease the space required for the landfill disposal. The High Strength concrete has become more popular in recent years owing to the extraordinary advantages it offers over the conventional concrete but at the same time strong enough to be used for the structural purpose. The aim of the present work is to study the attitude of coarse aggregate replaced with Recycled Aggregates in volume percentages of 10 , 20 %, 30 % and 40 % cement replaced with the GGBS and silica fume in weight percentages of 10 , 15 , 20 , 25 ,and 30. The conventional mix has been designed for M_(40) grade concrete. In this research, cubes, cylinders and beams of standard size have been cast and tested after 3 days, 7 days 28 days of curing period. The properties of concrete mix proportions were evaluated by measuring workability (using slump test), Compressive Strength. The mixing of GGBS, Silica Fume enhanced workability, compressive strength of the concrete for the types of cement. The Ordinary Portland Cement concrete mixtures including RA had almost the same behaviors.
