Effect of Partial Replacement of Cement with Silica Fume and Cellulose Fibre on Workability & Compressive Strength of High Performance Concrete

Pratik Patel, Dr. Indrajit N. Patel

Abstract :

High performance concrete exceeds the properties & constructability of normal concrete. Normal and special material are used to make these specially designed concretes that must meet a combination of strength and performance requirements. Special mixing, placing, and curing practices may be needed to produce and handle high performance concrete. High performance concrete is widely used in construction due its high strength, high workability, and high durability. The different types of pozzolonic materials like GGBS, Silica Fume, Fly Ash, RHA, etc. May be used in concrete as partial replacement of cement to add on durability properties owing to the pozzolanic properties of supplement and there by producing a better performance concrete as compared to conventional mix with more amount of virgin cement. This experimental instigations study the effect of rheological and engineering properties of with partial replacement of OPC by silica fume. Further investigations are also made to observe effect of inclusion of cellulose fie on the properties of fresh and harden concrete. This paper describes the experimental study of compacting factor and compressive strength through standard HPC test practice laid down by Bureau of Indian Standards,(BIS) and also describes the test results of different ingredients.
