Abstract
Concrete is the most widely used construction material due to its mechanical and durability properties. Due to the use of ordinary portland cement in concrete production, CO2; emissions occur from cement leading to environmental pollution. The objective of the current study is to minimize the cement content in the concrete production. in this regard, cement is replaced with ground granulated blast furnace slag, alkaline solution is used for alkali activation to develop geopolymeriziation process and this type of concrete produced is called as alkali-activated slag based geopolymer concrete. Most of the research works available are related to heat-cured flyash based geopolymer concrete and less work on ambient cured. The present work is one such alternative method in producing ambient cured ground granulated blast furnace slag geopolymer concrete. The compressive strength of ambient cured slag based geopolymer concrete with and without superplasticizer is 5.5% and 8.7% higher than ordinary portland cement concrete, respectively.
