Abstract

The paper investigates the possibility of using Granulated Blast Furnace Slag (GBFS) as a sand substitute in cement mortar in order to reduce environmental problems related to aggregate mining and waste disposal. In this study, cement mortar mix 1:3 and GBFS at 0, 25, 50, 75 and 100% replacement to natural sand for constant w/c ratio of 0.5 is considered. The flow characteristics of the mix and their compressive strengths at various ages are studied. It is observed that GBFS could be utilized partially as an alternative construction material for natural sand in mortar applications.


Description

In India, natural river sand (fine aggregate) is traditionally used in mortars and concrete. However, growing environmental restrictions to the exploitation of sand from river beds have resulted in a search for alternative sand, particularly near the larger metropolitan areas. This has brought in severe strains on the availability of sand forcing the construction industry to look for an alternative construction material. Thus, manufactured fine aggregates appear as an attractive alternative to natural fine aggregates for cement mortars and concrete.
