Influence Of Multiple Blended Binders On Engineering Properties And Durability Of Concrete

The influence of multiple blended binders in the forms of binary blended cement (BBC) and ternary blended cement (TBC) on the properties and performance of concrete is investigated. The mineral admixtures used are silica fume(SF), fly ash (FA), metakaolin (MK) and rice husk ash (RHA). They are used...
