IIJ10-01Experimental Investigation of Self Compacting Concrete

AUTHORS: Kumar Swaroop, Kapil Soni

Abstract: Concrete is a mixture of cement, sand, gravel and water which dries hard and strong and is used as a material for building. Concrete has to be heavily vibrated for flow into very intricate forms or forms that have a lot of reinforcing bars. Hence to overcome these defects the self-compacting concrete is used. Self-compacting concrete is a flowing concrete mixture that is able to consolidate under its own weight. The self-compacting concrete flows easily at suitable speed into formwork without blocking through the reinforcement without being heavily vibrated. This project deals with the self- compacting concrete where the cement is partially replaced with fly-ash and silica fume. Here Ordinary Portland Cement is replaced with 5%, 10%, 15%, 20% and 25% of fly-ash and 2.5%, 5%, 7.5%, 10% and 12.5% of silica fume. From the experimental investigations, it is observed that there is increase in the fresh properties (workability) and increase in the hardened properties (split-tensile strength and compressive strength) for replacement of silica fume. Similarly, there is increase in the fresh properties (workability) and decrease in the hardened properties (split-tensile strength and compressive strength) for replacement of fly ash.

IIJ10-02:Utilization of Geo Polymer in Concrete

AUTHORS: Yogendra Pradhan , Jeet Tiwari

Abstract: The development of sustainable construction and building materials with reduced environmental footprint in both manufacturing and operational phases of the material lifecycle is attracting increased interest in the housing and construction industry worldwide. Recent innovations have led to the development of geopolymer concrete, which combines the performance benefits and operational energy savings achievable through the use of lightweight concrete, with the emissions reductions obtained through the use of a geopolymer binder derived from fly ash. To bring a better understanding of the properties and potential large-scale benefits associated with the use of geopolymer concretes, this thesis addresses some of the sustainability questions currently facing the cement and concrete industry, in the context of the utilisation of geopolymer concretes (PFRC Polymer Fiber Reinforce Concrete) based either on ordinary Portland cement (OPC) or on geopolymer binders. The potential of geopolymer binders to provide enhanced fire resistance is also significant, and the basis of the geopolymer binding phases is important in bringing high temperature stability.

IIJ10-04:Experimental Investigation of Concrete Rubber Crumb on Different Structures

AUTHORS: Subhash Kumar Singh , Kapil Soni

Abstract:Solid waste management has gained a lot of attention of the research community now-a- days. Maintaining non-biodegradable waste is an international issue, out of the various solid waste, waste tyres, has become a problem which needs an immediate solution. Though waste tyre rubbers are already used as a fuel in many industries such as thermal power plant, cement kilns and brick kilns etc. Unfortunately, this kind of usage is not environment friendly and requires high cost. Thus, it was need of society to identify areas where tyre rubber can be used without much investment and at mass scale. The use of scrap tyre rubber in the preparation of concrete has been thought as an alternative for disposal of such waste to protect the environment.In this study an attempt has been made to identify the various properties necessary for the design of concrete mix by replacing aggregates with crumb tyre rubber. M20 grade concrete has been chosen as the reference concrete specimen. Scrap tyre rubber powder, has been used as fine aggregate with the replacement of conventional fine aggregate.

IIJ10-05APPLICATION OF NON DESTRUCTIVE TEST FOR STRUCTURAL HEALTH MONITORING – STATE OF THE ART REVIEW                                                                                             

AUTHORS: Akshay Chourasiya, Asst. Prof. Premit Patil, HOD Prof. Kapil Soni

Abstract: The concept of non-destructive testing (NDT) is to obtain material properties “in place” specimens without the destruction of the specimens and to do the structural health monitoring. NDT using Rebound hammer, Ultra pulse velocity, Half-cell potential, core cutter, carbonation depth, rebar locator, Rapid chloride penetration test, electric resistivity meter test and vibration base analysis by data analoger are very popular and highly effective in conducting structural health monitoring. The structure can be investigated by using a visual inspection, NDT, laboratory and field test performance. In this article a review of these tests have been provided to conduct effective structural health monitoring of a RCC structure.

Keywords: Non-destructive test, visual inspection, corrosion, compressive strength
