jce.7.1.10363 Mechanical and Durability Characteristics of Wollastonite Based Cement Concrete J. Bharath Kumar K. Ramujee Journal on Civil Engineering 2249-0779 7 1 1 7 Wollastonite, Fly Ash, Mineral Admixtures, Mechanical Studies, Durability Studies Manufacturing of cement is always accompanied by CO2 emission and associated problems due to emission of smoke and dust, which are the most vital sources of increasing the pollution and global warming. Hence, the need for utilization of alternate pozzolanic materials like fly ash, silica fume, metakaolin, etc., has become a mandate due to its benefits of improved mechanical and durability characteristics. Most often these are either by-products obtained from industries or naturally occurring minerals. The present investigation is focused towards determining the performance of Wollastonite and fly-ash in cement concrete by determining mechanical and durability characteristics by conducting tests to determine compressive strength, tensile strength, bond strength, Acid attack, Alkali attack, and Rapid Chloride Penetration Test (RCPT). The results of the study on mortars and concretes would be presented in a relative manner quantifying the performance criterion in terms of strength and durability.
