Influence of GGBS on Mechanical Properties of Low Traffic Concrete Paver Blocks (original) (raw)

Supplementary cementitious materials (SCM) are the integral part of modern concrete with significant enhancement in concrete performance. Low cost of production, low heat of hydration along with improved mechanical properties encourage the replacement of ordinary Portland cement (OPC) with SCMs to a greater extent. The study focusses on influence of Ground granulated blast furnace slag (GGBS) as SCM in production of concrete paver blocks. Compressive strength, split tensile strength, and flexural strength are the properties under consideration. Improved compressive strength and flexural strength was observed in blended concrete with 20% and 40% GGBS replacement levels.
