Using tyres wastes as aggregates in concrete to form rubcrete – mix for engin...eSAT Journals
Abstract This paper presents the results, obtained after replacement of fine and coarse aggregates, in concrete mix, with tyre rubber. The tyre rubber, which has been used in the present study, is obtained after the mechanical trituration process of post – consumed tyres from trucks. Researchers have investigated, over the years, the use of recycled tyre rubber waste as a replacement for aggregate in concrete and its effectiveness. “Rubcrete-Mix” which would result from such replacement is found to have many engineering applications and holds promise in future. Rubcrete also possesses good mechanical properties and is considered to be one of the best and economical ways of recycling the used tyres. The present experimental study has the aim of arriving at the optimum quantity of the replacement material for the aggregates in concrete mixtures, for various engineering applications. For achieving a proper bond with the surrounding concrete paste, the recycled aggregates have been designed with respect to their size, shape and gradation. With the water – cement ratio being kept constant fine and coarse aggregate has been replaced with tyre rubber powder and chipped rubber and also cement has been replaced with silica fume. In preparing the concrete, Portland slag cement has been used along with super plasticizer less than 1% by weight of cement to achieve required workability of the resulting concrete. Furthermore, durability studies have been conducted and mixes have been designed for M30 grade concrete. Keywords: Concrete Mix, Mechanical Properties, Rubber Powder, Chipped Rubber, Silica fume.
Economical eco friendly light-weight building blocks using waste paper - pape...Prakash Kumar Sekar
The major component in any construction activity is the cost of the material. In developing countries, the untapped or unused resources are needed to be identified for its potential use in the construction sectors. The one such resource is waste paper. Paper pulp added with cement and sand hardens and forms a light weight construction material called Papercrete, which satisfies many of the engineering properties needed for construction. Papercrete has advantages like low-cost, economical and it is eco-friendly. In this research, papercrete blocks are created and their engineering properties are studied. It is to be noted that under compression papercrete fails slowly in a ductile manner but there was no earlier reliable research findings relating compressive stress with compressive strain which is covered in this paper.
Partial replacement of cement in concrete using waste glass powder and m sand...eSAT Journals
Abstract: The traditional Taguchi method is widely used for optimizing the process parameters of a single response problem. Optimization of a single response results the non-optimum values for remaining. But, the performance of a machining process is often evaluated by several quality responses. Under such circumstances, multi-characteristics response optimization may be the solution to optimize multi-responses simultaneously. In the present work, a multi-characteristics response optimization model based on Taguchi and Utility concept is used to optimize process parameters, such as magnetic flux, rotational speed of CFG rod, shape of CFG rod, number of cycles, abrasive-to-iron ratio and abrasive particle size on multiple performance characteristics, namely, surface roughness (Ra) and material removal (MR) during polishing of hollow cylindrical brass work-pieces with Centrifugal-Magnetic Force Assisted Abrasive Flow Machining (CMA2FM) Process. Taguchi’s L27 orthogonal array (OA) is selected for experimental planning. The ANOVA and F-tests are used to analyze the results. It is found that all the input parameters significantly improve the Utility function comprising of two quality characteristics (MR and %ΔRa). Further, the confirmation tests are conducted and the results are found to be within the confidence interval.

Experimental study on Use of Waste Glass as admixture in ConcreteIJSRD
Glass is utilized as a part of numerous structures in everyday life. It has restricted life and after use it is either stock heaped or sent to landfills. Since glass is non-biodegradable, landfills don't give a situation well-disposed arrangement. Thus, there is solid need to use waste glasses. Many efforts has already been made in concrete engineering as a partial replacement of cement or fine aggregate or coarse aggregate. In this experiment we use waste glass powder as a partial replacement of cement and a comparative study has been made with other admixture such as fly ash and silica fume. A series of test were conducted with partial replacement of glass by 15% and 30% to weight of cement where as we have used only 15% of partial replacement in case of fly ash and silica fume just to compare the results with glass at 15% and 30%. The present study demonstrates that waste glass, if ground finer than 100µm demonstrates a pozzolanic conduct. It responds with lime at early time phase of hydration forming extra CSH gel along these lines shaping denser bond matrix. The early utilization of alkalis by glass particles moderate alkali silica reaction consequently expands durability of cement.

A Compatibility Study on Different Types of Cement and Plasticizerijsrd.com
It has long been a concrete technologist's dream to discover method of making concrete at the lowest possible water/cement ratio while maintaining a high workability. To a considerable extent this dream has been fulfilled with the advent of super plasticizers. It has added a new dimension to the application of admixtures with regards to production of high strength and flow able concretes. It is now possible to produce concrete with compressive strength of the order of 90Mpa (90 N/mm2). In the wake of energy conservation policy and diminishing supplies of high quality raw materials, there is a need to use marginal quality cements and aggregates for the production of concrete. In such instances the use of plasticizers/super plasticizers permits the production of concrete at low water/ cement ratios. We have taken ultra tech opc cement & coromandal ppc cement to find the compatibility by adding perma plast (plasticizer). The water cement ratio was maintained as 0.40 &0.45 for OPC & PPC respectively. To study the effect of these PP on various properties of concrete. The dosage of plasticizers/super plasticizers was measured as 1.5% for Perma plast for OPC & 1.3% for PPC by the weight of cement.

Cellular Lightweight Concrete is also known as CLC. In other words, CLC is also known as foamed concrete. The CLC is widely used for construction purposes as it has various advantages and usage than the traditional concrete bricks.
The foamed concrete is manufactured from mixing of Portland cement, sand, fly ash, water and performed foam in varied proportions. This CLC (Cellular Lightweight Concrete) can be produced at building sites with the use of machines and molds used for normal concrete.
One of an important characteristic of foamed concrete is it has self-compacting property as there is no compaction is required. And also, it easily flows out from the pump to fill the mold. With this property is can be pumped to maximum distance and height.
For continuous cellular lightweight concrete is manufactured by mixing light mortar and preformed foam under pressure in a special static mixer.
This paper contains an efficient building design for cyclone resistivity. and have the capacity to stand against high wind pressure. the building design must be followed in costal areas so it can resist the high wind pressure and also to the cyclone.
STUDIES ON DURABILITY, STRENGTH AND STRUCTURAL PROPERTIES OF FLYASH BASED PAP...Satyajit Behera
presentation shows the strength durability and structural properties of the flyash based papercrete bricks. the papercrete bricks are the new type material for the buildings.
This document contain all topics of research methodology of module-3 according to the syllabus of BPUT odisha. The document is done for the PG and PHD students who are doing research.
The objective of the paper is to show the effect of the earthquake on different types of foundations such as shallow, mat/raft, pile and structures like gravity dam, arch dam etc. The reaction of soil to the loading of the building when a building undergoes an earthquake disturbance as a behaviour of deflection is known as the soil structure interaction. The movement of ground during the Earthquake induces kinematic and inertial loading which decreases the bearing capacity and increments the settlement of shallow foundations. In seismic regions, where kinematic interactions have been observed, the mat foundations experiences overturning moments. Pile foundations are influenced by both kinematic and inertial interactions which causes many failures. The convoluted oscillating arrangement of acceleration and ground motion in a gravity dam, developing ephemeral dynamic loads because of inertia of dam and confined water is the seismic activity generated in these dams. The arch dam foundations undergoes effects of inertia and flexibility due to the propagation of seismic waves.
