Durability Studies in Concrete and Mortar Mixed with Supplementary Materials- A Review

Abstract

Supplementary materials (SMs) have been widely used all over the world in ready-mixed concrete due to
their economic and environmental benefits; hence, they have drawn much attention in recent years. Durability of
concrete is defined as its ability to resist weathering action, chemical attack, abrasion or any other process of
detoriation. It also includes the effects of quality and serviceability of concrete when exposed to sulphate and chloride
attacks. Supplementary materials may contain fly ash (FA), silica fume (SF), Nano Silica, ground granulated blast
furnace slag (GGBFS), rice husk ash (RHA), metakaolin (MK) and palm oil fuel ash (POFA), to name a few. In this
reviewed paper we study on the concept how to enhance the durability of concrete and mortar mix with supplementary
materials as additive and study about using supplementary materials and its applications and its effect on concrete
properties. Paper discussed about Nano Silica used as supplementary material admixture in concrete.
