Abstract

Abstract: This paper opens up how the properties of seashell mix concrete influenced by the effect of ground granulated blast furnace slag (GGBS). This experimental program consists of thirteen concrete mixes. One is conventional concrete & other concrete mixes are formed by the partial replacement of fine aggregate with crushed seashell and cement with GGBS. The proportion of crushed seashell was added 0, 10 %, 20 % & 30 % to the conventional concrete. Then seashell mix concrete of 10 % was blended with 10 %, 20 % & 30 % of GGBS mix concrete and like this 20 %, 30 % of seashell mix concrete was intermixed with 10 %, 20 % & 30 % of GGBS mix concrete respectively. For this experiment M30 grade concrete mix was prepared. Tests like slump test for workability of concrete were carried out on different mixes of fresh concrete. Also, on hardened concrete samples of different mix, test like compressive, split-tensile & flexural strength test were allotted after 7 days and 28 days of curing under water. From the experimental observations show that use of seashell in concrete decreases the strength gradually but in case of GGBS, the strength increases gradually in all type of concrete mixes. The result declares higher compressive, flexural and split-tensile strength at 10 % partial replacement of fine aggregate with crushed seashell and 20 % partial replacement of cement with GGBS.
