Abstract The excessive use of cement in the construction industry has caused many undesirable consequences. Replacement of cement with industrial by-products like fly ash (FA), ground granulated blast furnace slag (GGBFS), silica fume (SF), metakaolin, rice husk ash, etc., as the mineral admixtures offers several advantages in this modern era of sustainability in construction practice. This paper presents the experimental investigations for assessing the strength properties of the concrete made using the pozzolanic waste materials, i.e. supplementary cementitious materials (SCMs) such as FA, GGBFS and SF as the cement replacing materials. Eight trial mixes were prepared using these materials with varying amount of ordinary Portland cement. These SCMs were kept in equal proportions in all the eight trial mixes. Moreover, superplasticizer was also used for bringing improvement in the workability. The compressive strengths corresponding to the curing period of 7, 28, 40 and 90 days along with the flexural and indirect tensile strengths corresponding to 7, 28 and 40 days curing were evaluated. The study concludes that industrial waste materials can be used as partial replacement of cement and can render sustainable concrete for use in the rigid pavement construction.

Introduction The concrete is the prominent construction material due to several benefits with respect to strength, durability, adoptability and economy. Lot of efforts was taken for improving the quality of concrete by resorting to the various ways for maximizing its performance level. Nowadays, development of special types of concretes has necessitated the use of mineral and chemical admixtures for improving its performance. Various by-products generated by the industries find application in concrete in the context of economic viability, preservation of environment, improvement in the workability of wet concrete and strength and durability of the hardened concrete; and reduced heat of hydration. In developing country like India, more thrust is be
