Book excerpt: INTRODUCTION In the pursuit of developing new comforts and luxuries the greedy modern man is unintentionally got entangled into several environmental problems. Once the solar energy arrives on the earth, the earth’s surface heats up and begins to emit terrestrial radiation back into the atmosphere. As carbon dioxide, water vapour, methane, nitrous oxide, ozone, chlorofluorocarbons (CFC’s) and some other minor gases are nearly opaque, they obstruct or trap the outgoing terrestrial radiation or heat and makes the globe warmer than it be otherwise [John Houghton, 1997].

Download or read book Waste Materials Used in Concrete Manufacturing written by Satish Chandra and published by Elsevier. This book was released on 1996-12-31 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: The environmental aspects involved in the production and use of cement, concrete and other building materials are of growing importance. CO2 emissions are 0.8-1.3 ton/ton of cement production in dry process. SO2 emission is also very high, but is dependent upon the type of fuel used. Energy consumption is also very high at 100-150 KWT/ton of cement produced. It is costly to erect new cement plants. Substitution of waste materials will conserve dwindling resources, and will avoid the environmental and ecological damages caused by quarrying and exploitation of the raw materials for making cement. To some extent, it will help to solve the problem otherwise encountered in disposing of the wastes. Partial replacement of clinker or portland cement by slag, fly ash, silica fume and natural rock minerals illustrates these aspects. Partial replacement by natural materials that require little or no processing, such as pozzolans, calcined clays, etc., saves energy and decreases emission of gases. The output of waste materials suitable as cement replacement (slags, fly ashes, silica fumes, rice husk ash, etc.) is more than double that of cement production. These waste materials can partly be used, or processed, to produce materials suitable as aggregates or fillers in concrete. These can also be used as clinker raw materials, or processed into cementing systems. New grinding and mixing technology will make the use of these secondary materials simpler. Developments in chemical admixtures: superplasticizers, air entraining agents, etc., help in controlling production techniques and, in achieving the desired properties in concrete. Use of waste products is not only a partial solution to environmental and ecological problems; it significantly improves the microstructure, and consequently the durability properties of concrete, which are difficult to achieve by the use of pure portland cement. The aim is not only to make the cements and concrete less expensive, but to provide a blend of tailored properties of waste materials and portland cements suitable for specified purpose. This requires a better understanding of chemistry, and materials science. There is an increasing demand for better understanding of material properties, as well as better control of the microstructure developing in the construction material, to increase durability. The combination of different binders and modifiers to produce cheaper and more durable building materials will solve to some extent the ecological and environmental problems.

Download or read book Chemical Transformation of Rice Husk Ash for Sustainable Constructable and Durable Binary Cementitious System written by Lapyote Prasittisopin and published by . This book was released on 2014 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of cement and concrete results in the production of large amounts of CO2 emissions which can have significant negative environmental impacts. Using supplementary cementing materials (SCMs) as a cement replacement is an effective solution to reduce these negative environmental impacts, as most SCMs are waste by-products from other industries. Rice husk ash (RHA) is one such by-product material. RHA is produced from the burning of rice husks for the production of electricity. This material consists mostly of amorphous silica and has high potential to be used as a SCM. However, the use of RHA is limited. This is due to its cellular, honeycomb-like morphology. This morphology absorbs mix water and reduces the workability of fresh mixtures containing RHA. Reducing RHA particle size can improve the workability of cementitious systems containing RHA. However, reducing RHA particle size with mechanical grinding is time-consuming and costly. This dissertation evaluates the development of a new chemical transformation method to reduce particle size and to eliminate the RHA cellular, honeycomb-like morphology of the RHA. This dissertation focuses on developing a chemical transformation process for RHA, assessing the performance of systems containing chemically transformed RHA (t-RHA), and evaluating the influence of mixing and transport variables on the characteristics of RHA blended cement systems. Results indicate that using the chemical transformation process can be an alternative method to reduce RHA particle size and eliminate the cellular, honeycomb-like morphology of the RHA. This results in the improved flowability, higher chemical shrinkage, faster set, reduced porosity, and increased early-age strength of blended cementitious systems when compared to the 100% portland cement (PC) system. When mixing time and mixer revolution counts increase, using t-RHA exhibits lower flow reduction rates and lower chloride diffusivity than the 100% PC system. However, the performance of the t-RHA and the as-receive RHA (AR-RHA) system are similar with increasing mixing time and mixer revolutions count.

This book was released on 2018-09-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacture of Value Added Products from Rice Husk (Hull) and Rice Husk Ash (RHA) (Precipitated Silica, Activated Carbon, Cement, Electricity, Ethanol, Hardboard, Oxalic Acid, Paper, Particle Board, Rice Husk Briquettes, Rice Husk Pellet, Silicon, Sodium Silicate Projects) Rice husk is the outermost layer of protection encasing a rice grain. Rice husk was largely considered a waste product that was often burned or dumped on landfills. Many ways are being thought for disposal of rice husk and only a small quantity of rice husk is used in agricultural field as a fertilizer, or as bedding and for stabilisation of soils. Therefore, the use of rice husk as rice husk ash is one of the most viable solution. The husk can be used for poultry farming, composting or burning. In the case of burning, it has been used as biomass to power reactors to generate thermal or electrical energy. India is a major rice producing country and the husk generated during milling is mostly used as a fuel in the boilers for processing paddy, producing energy through direct combustion and / or by gasification. The rice husk ash causes more environmental pollution and its disposal becomes a problem, hence requires attention regarding its disposal and its reuse. The ash is mainly composed of carbon and silica due to which it is used to manufacture different value added products. This book provides thorough information to utilize RHA with process pathway for economically valuable products. This handbook explains manufacturing process with flow diagrams of various value added products from rice husk & rice husk ash, photographs of plant & machinery with supplier’s contact details and sample plant layout & process flow sheets. The major contents of the book are rice husk, rice husk ash RHA), precipitated silica from rice husk ash, activated carbon from rice husk, cement from rice husk ash, electricity from rice husk, ethanol from rice husk, hardboard from rice husk, oxalic acid from rice husk, paper from rice husk, particle board from rice husk, rice husk briquettes, rice husk pellet, silicon from rice husk, sodium silicate from rice husk, packaging. This book will be a mile stone for the entrepreneurs, existing units, professionals, libraries and others interested in recovery of value added products from rice husk (rice hull) & rice husk ash to explore an economic way for recycle and reuse of agricultural waste.
