Abstract

This paper presents the effects of using Fly Ash (class F) and Alccofine materials on performance of high-strength concrete with M60 grade of IS cube specimen. Fly ash replacement varies from 26% to 18% and Alccofine replacement varies from 4% to 12%. We are using Poly Carboxylate Ether based superplasticizer for achieving workability of concrete. Dosage of superplasticizer is same for all mix proportions. Five types of mix proportions containing Fly Ash and Alccofine with different proportions in addition to ordinary Portland cement were investigated and tested for compressive strength, split tensile strength, flexural strength and loss in weight and compressive strength for durability aspects. The result shows that all the concretes achieve compressive strength higher than 41 MPa that is required for high strength concrete as per ACI 363. It is also observed that the strength gain at 28 to 56 days was higher than 7 to 28 days. Durability characteristics of high strength concrete with admixtures containing class F Fly Ash and Alccofine were conducted by acid resistance and sulphate attack at 28 days. The result shows that fly ash and Alccofine added as a cement replacement in concrete offers good response for durability criteria.
