Durability of Portland Slag Cement Mortar Made with Non Potable Water

Abstract

This research work reveals that durability of Portland slag cement (PSC) mortar made with non potable water.
Fourteen water treatment plants were found out in the Narasaraopet municipality region in Guntur district, Andhra Pradesh,
India. All plants are extracting ground water and treating through Reverse Osmosis (RO) process. During water treatment,
approximately plants are discharging 1,00,000 L/day from out lets into side drains in Narasaraopet municipality.Physical
and chemical analysis was carried out on fourteen plants outlet water and distilled water as per producer described in
APHA.In the present work, based on the concentrations of constituent’s in outlet water, four typical plants i.e.,
Narasaraopeta Engineering College (NECWW), Patan Khasim Charitable Trust (PKTWW), Mahmadh Khasim Charitable
Trust (MKTWW) and Amara (ARWW) were considered. Test specimens made with four typical plants outlet waters on
physical properties i.e., setting times, compressive strength, flexural strength were performed in laboratories and compared
same with reference specimens i.e., made with Distilled Water (DW). And also magnesium sulphate effect on test and
reference specimens was carried out. No significant change was observed in initial and finial setting time of test specimens
made with four plants outlet waters compared to that of reference. Almost, no change was observed in 90 days compressive
and flexural strengths in test specimens of four plants outlet waters compared with reference specimens. Compressive
strength loss in test and reference specimens due to magnesium sulphate effect was also same. XRD technique was employed
to find out main hydrate compounds formed in cement past
