Experimental Investigation on Strength and Durability Characteristics of Multi Blended Cement Concrete

Abstract

The main aim of the present study is to determine the strength of concrete mix of M30 grade, with partial replacement of cement with Silica fume, Rice husk ash and FLY-ASH. Portland cement is the most important ingredient of concrete and is a versatile and relatively high cost material. Large scale production of cement is causing environmental problems on one hand and depletion of natural resources on other hand. Hence, the researchers are currently focused on use of waste material having cementing properties (such as fly ash, GGBS, metakaloin, silica fume, rice husk ash) which can be added in concrete as partial replacement of cement, without compromising on its strength and durability, which will result in decrease of cement production thus reduction in emission in greenhouse gases, in addition to sustainable management of the waste. This paper presents a study on mechanical and durability properties of ternary blend is a mixture of three products (i.e. portland cement and two SCMs ) and quaternary blend is a mixture of four products (i.e. portland cement and three SCMs ). The pozzolanic material such as fly ash, silica fume, rice husk ash were used as a cement replacing materials in conjuction with ordinary Portland cement. This paper presents a study on mechanical and durability properties of concrete made with multi component cement. Study includes concept of multi blended cement exploits the beneficial characteristics of all pozzolanic materials in producing better concrete.
