Study of Work Ability Durability and Strength of Concrete Using Silica Fume

Kuldeep Bhatt | Shubham Singh [4]

Abstract: In this present study use silica fume as a admixture in the concrete. Several researches have towards investigation the hardened property of concrete when added Silica Fume. In this present study to investigate the workability, durability and strength of concrete with partial replacement of cement by silica fume. The percentages are used 0 %, 5 %, 10 %, 15 %, 20 % and specimen carried out at 7, 14 and 28 days of M30 Grade concrete with a fixed water cement ration 0.45. For workability properties ( slump test, Vee Bee test) were carried out at 0 %, 5 %, 10 %, 15 %, 20 %, durability properties (water absorption, sulphate attack) were carried out at 7, 28 days and hardened properties (compressive strength, flexural strength) were carried out at 7, 14, 28 days. Based on experimental investigation the concrete mix were found with increase in the content of silica fume as observed from the reduction in the slump values of concrete mix and increment of time in seconds were found in vee-bee test, durability were found decrease compressive strength of sulphate attack and strength (compressive strength and flexural strength) were found increase from 0 % to 5 % to 10 % to 15 % and both are decrease on 20 % addition of silica fume. In this study use silica fume of size 1-150 nm improve the compressive strength of concrete. The test conducted on it shows a considerable increase in early-age parameters of workability, durability and strength of concrete using silica fumes. The strength increase was observed with the increase in the percentage of silica fume and decrease of strength at a particular percentage.

Keywords: Silica fume, workability, durability, compressive strength, flexural strength
