Enhancement of Strength Characteristics of Poorly Graded Soil by Flyash and Cement

Fly Ash is the waste material, which is obtained after burning coal in Thermal Power Plants. It can be used as a stabilizer for soil due to its pozzolanic effect or an inherent self-hardening property under favourable conditions of moisture and compaction. This project aims at increasing the strength of poorly graded soils by using Fly Ash and cement as admixtures. Some percentage of Fly Ash without any additives was utilized so as to reduce the cost of construction and this is a good method for disposal of it. Fly Ash was added in various percentages like 10, 20, 30 and 40 percentages by volume . 

Initially all basic Geotechnical properties of the soil such as liquid limit, plastic limit, shrinkage limit, Grain Size Analysis, Specific Gravity, Free Swell Index, Unconfined Compressive Strength, OMC and MDD were determined. Later on the stabilized mixes were tested for CBR California Bearing Ratio which is an indirect measurement of strength. After the detailed experimental investigation it is observed that 30 addition of Fly Ash has shown maximum strengths, so that to obtain much more strengths cement was added in 2, 5, 8 and 10 percentages to this optimum mix of Fly Ash with soil. 

After that the soil mixes were tested for CBR California Bearing Ratio to check it's feasibility in Flexible Pavement constructions. The strengths were checked in both Unsoaked and soaked conditions and at various curing periods like 7 and 28 Days. Among all proportions 30 Fly Ash 8 of the cement has shown maximum strengths, so that it was decided as optimum mix. Maximum strengths were obtained at 28 days curing period for all proportions of mixes so that this period is decided as optimum curing period. Eventually this project work facilitates an economical, strong and durable construction material for Flexible Pavements.

Artificial Intelligence Basics and Terminology

The Artificial intelligence field continues to be plagued by what can only be described as 'bold promises for the future syndrome'. Research in AI has built upon the tools and techniques of many different disciplines, including formal logic, probability theory, decision theory, management science, linguistic philosophy. However, the application of these disciplines in artificial intelligence has necessitated the development of many enhancements and extensions. Since the invention of computers or machines, their capability to perform various tasks went on growing exponentially. Humans have developed the power of computer systems in terms of their diverse working domains, their increasing speed and reducing size with respect to time.

Study on Alternative Fuels for Compression Ignition Engines

This review paper studies potential alternative fuels for automobile engine application for compression ignition CI engines. Diesel engines are favorable for use due to its fuel consumption and higher torque. Nowadays, we are facing the difficulties of crisis of fossil fuels due to rapid increase in demand of it in automobiles and industries. The use of fossil fuels further leads to environmental degradation by polluting the air. Hence, in the present era, more importance is given on alternative source of energy for running the engines. The representative alternative fuels for CI engines include biodiesel, di-methyl ether DME , and jet propellent-8 JP-8 .

Naphtha can be also used as an alternative fuel for advanced combustion in premixed charge compression ignition. The production methods, storage characteristics, and the supply chain of each alternative fuel are discussed, and are followed by concentrating the attention on the main research topics for the mentioned alternative fuels. Literature survey investigates on relative advantages and disadvantages of alternative fuels for application to engine combustion.

The engine combustion study consists of the combustion process from spray development, air-fuel mixing characteristics, to the final combustion product formation, which are studied for each alternative fuel. An overview is obtained for alternative fuels together with summaries of engine combustion characteristics for each fuel, in addition to its current status and future scopes.

Characteristic Behaviour of Aluminium Metal Matrix Composites A Review

This paper presents a summary of work reported on Aluminium metal matrix composites with different reinforcements. Aluminium metal matrix has growing demand in aircraft, automotive and other industries due to its light weight, high strength to weight ratio, corrosion resistance and workability. The work is done by reviewed of research Papers, Articles, Magazines, references books etc. The present work focus on mechanical properties and surface texture of aluminum matrix composites AMCs reinforced by silicon carbide, fly ash, TiO2, graphene and B4C and with different wt by using stir casting technique. 

Each reinforced material has an individual property which when added improves the properties of the base alloy. Effect of different reinforcement on AMCs on the microstructure analyses and mechanical properties like tensile strength, hardness, density, electrical resistivity and wear behaviour is also discussed in detail. Major applications of different AMCs are also highlighted in this work.

A Preliminary Study on Aerated Geopolymer using Calcium Carbide

In this paper a preliminary study is conducted on use of calcium carbide as an aerator in geopolymer paste and mortar. A 12 mole sodium hydroxide with sodium silicate solution was mixed with fly ash in 1 2 ratio to create geopolymer paste. To make mortar, graded sand was used as 3- parts with 1-part paste. Calcium carbide was added in various percentages viz 1 , 2 , 3 , 4 and 5 to paste as first trial and mortar as second trial. Calcium carbide reacts with water to produce acetylene gas and heat. 

Acetylene gas works as aerator and heat developed helps in ambient curing of geopolymer paste and mortar. The mixes are cast into cubes of 50sqcm and properties such as density, water absorption and compressive strength were evaluated. The 3 calcium carbide paste showed less density, more water absorption and less compressive strength. The mortar's density was hovering around 1800kg m3, water absorption was less than paste and compressive strength was maximum for 4 calcium carbide.

Development of Hybrid Fibrous Panel for Controlling Acoustics in Home Theatre Conference Hall

Human ear will acknowledge as sound when frequency is in the range of 20 to 20000 Hz and more sensitive in the range of 500 - 4000 Hz. Heat and sound insulation panels are generally composed of nonwoven porous synthetic materials such as rock wool, glass wool, polyurethane, polyester and etc. Though these materials have excellent acoustic properties at high frequencies, their structural properties are not enough to defend against low frequency noise. Multi-purpose concert halls face a dilemma and they host classical music concerts, rock concerts and spoken word performances in a matter of a short period. These different performance types require significantly different acoustic conditions in order to provide the best sound quality to both the performers and the audience.

Micro perforated panel absorber backed by air gap is also used in auditoriums and effective only in absorbing specified range of frequencies low frequency . Hence, it is clear that one type of acoustical absorbers is unable to attenuate wide spectrum of frequency noise. Increased usage of synthetic sound absorption materials leads to higher CO2 emission and other environmental issues. 

Therefore, many researches turned towards the production of insulating materials by using natural and bio based materials. Natural materials are becoming a valid alternative to synthetic materials and composite panel is proposed with coir fibre alone which is organic in nature, have excellent insulation against thermal and sound and more resistant to fungi rot. 

The present work has been focused on the sound absorption performance nonwoven porous coir matt mounted with and with-out air gap, perforated panel faced porous coir matt with and with-out air gap and perforated panel mounted with air gap.
