STUDY ON STRENGTH AND DURABILITY CHARACTERISTICS OF TERNARY CONCRETE

This paper presents part of the results of an ongoing laboratory study carried out to study on strength and durability characteristics of ternary concrete made with and without ternary mixtures of cement-fly ash- silica fume. In the present work an attempt has been made to study the strength properties of ternary concrete in compression, tens ion and flexure and also durability aspects of ternary blended concrete. In the investigation, M2 5 Grade concrete mix is designed with different percentages of cementitious materials (5%, 7.5%, 10 % & 12.5%) and tests are conducted for compressive strength, split tensile strength and flexure strengths at 7, 28 and 56 days. Test results indicate that the replacement of cement by 10% had attained a maximum strength in M25 Grade concrete. The results obtained thus are encouraging for partial replacement.
