Effectiveness of Portland Pozolana Cement (PPC) in Mitigation Of ASR

( Volume 3 Issue 3,March 2016 ) OPEN ACCESS

It is the well known fact that alkali aggregate reactions are one of the predominant causes of concrete deterioration. Alkali Silica Reaction (ASR) is a chemical reaction between the alkalis in Portland cement and certain types of silica minerals present in some aggregates. ASR is very harmful for the concrete structures and reduces the service life of the structures. To retard ASR rate, the process of   dilution of alkalis by increasing silica content using Portland Pozzolana Cement or Portland Slag Cement or some mineral additives like fly ash, Micro Silica, Metakaolin, etc., are very effective. The aim of the current study was to determine the effectiveness of Portland Pozzolana Cement (PPC) in mitigation of ASR expansion while used in place of Ordinary Portland Cement (OPC) for the aggregate sample of five different quarries. The outcome of the study is presented in this paper which is effective in controlling ASR.
