Experimental investigation in developing low cost

Paper making generally produces a large amount of solid waste. Minimum paste will mean less quantity of cement and less water, which will further mean increased economy, higher strength, lower shrinkage and greater durability. Hypo sludge behaves like cement because of silica and magnesium properties.

To reduce disposal and pollution problems emanating from these industrial wastes, it is most essential to develop profitable building materials from them.

For this, the hypo sludge is used as partial replacement in the concrete as high performance concrete.

Experimental Investigation in Developing Low Cost Concrete from Paper Industry Waste

Paper making generally produces a large amount of solid waste. Paper fibers can be recycled only a limited number of times before they become too short or weak to make high quality paper.

Keeping this in view, investigations were undertaken to produce low cast concrete by blending various ratios of cement with hypo sludge. By utilizing this waste the strength will be increased and also cost reduction in the concrete is achieved.

These materials pose problems of disposal and health hazards. It means that the broken, low- quality paper fibers are separated out to become waste sludge. From the preliminary waste named as hypo sludge due to its low calcium is taken out for our project to replace the cement utilization in concrete.

Many tests were conducted to cement some of them are consistency tests, setting tests, soundness tests, etc. Worse yet, some of the wastes are land spread on cropland as a disposal technique, raising concerns about trace contaminants building up in soil or running off into area lakes and streams.

Some companies burn their sludge in incinerators, contributing to our serious air pollution problems. The wastes like phosphogypsum, fluorogypsum and red mud contain obnoxious impurities which adversely affect the strength and other properties of building materials based on them.

Keeping this in view, investigations were undertaken to produce low cast concrete by blending various ratios of cement with hypo sludge. Hypo Sludge The following tables shows the hypo sludge chemical properties and comparison between cement and hypo sludge.

Experimental Investigation In Developing Low Cost Concrete From Paper Industry Waste

Some companies burn their sludge in incinerators, contributing to our serious air pollution problems. For producing 4million tones of cement, they emit 1 million ton green house gases are emitted.

Hypo Sludge, Pozzolanic Property, supplementary cementitious materials. Out of the total production, ordinary Portland cement accounts for about percent.

Worse yet, some of the wastes are land spread on cropland as a disposal technique, raising concerns about trace contaminants building up in soil or running off into area lakes and streams. Coarse Aggregate The fractions from 80 mm to 4.

This paper mill sludge consumes a large percentage of local landfill space for each and every year.

Out of several wastes being produced at present, the use of phosphogypsum, flurogypsum, lime sludge, hypo sludge, red mud, and mine tailing is of paramount significance to protect the environment. Also, to reduce the environmental degradation, this sludge has been avoided in mass level disposal in land.

This silica and magnesium improve the setting of the concrete. The shiny finish on glossy magazine-type paper is produced using a fine kaolin clay coating, which also becomes solid waste during recycling. These materials pose problems of disposal and health hazards.

Mortar contains of size of 4. Further during manufacturing of 1 tonnes of Ordinary Portland Cement an equal amount of carbon-di-oxide are released into the atmosphere.

Due to the cement production green house gases are emitted in the atmosphere. The carbon-di-oxide emissions act as a silent Killer in the environment as various forms.EXPERIMENTAL INVESTIGATION IN DEVELOPMENT LOW COST CONCRETE BY USING BRICK POWDER AND QUARTZ DUST In developing countries, Quartz Objectives of the experimental investigation are as follows: 1) To study the properties of fresh concrete this is cast by.

Numerical investigation of developing convective heat transfer in a rotating high heat transfer coefficient and low fabrication cost compared to many other heat exchangers with either active or passive design for convective heat transfer L. SantiniAn experimental investigation regarding the laminar to turbulent flow transition in.

The Control Performance of TLCD and TMD: Experimental Investigation. for the following features: low cost, easy aims at developing a theoretical and experimental investigation of a. Keeping this in view, investigations were undertaken to produce low cast concrete by blending various ratios of cement with hypo sludge.

This project is concerned with experimental investigation on strength of concrete and optimum percentage of the partial replacement by replacing cement via 10%, 20%, 30%, 40%, 50%, 60% and 70% of. Over million tones of industrial wastes are being produced per annum by chemical and agricultural process in India.

These materials pose problems of disposal and health hazards. The wastes like phosphogypsum, fluorogypsum and red. Experimental investigation of a low cost passive strategy to improve the performance of Building Integrated Photovoltaic systems.

with the aim of developing innovative technological solutions for energy efficient architectures.
