Experimental Approach towards Analysis of Effective Utilization of Natural and Artificial Substances in Concrete

The demand for material has been continuously rising with the increasing need for housing both in rural and urban areas. The resource used to manufacture construction materials affect the environment by depleting natural resources, using energy, and releasing pollutants on the land and water .Commercial exploitation of traditional building materials by various industries has aggravated the situation. It has, therefore, become necessary to think over this problem seriously and to provide some sustainable solution to make the alternative materials available to solve the housing problem. With consideration of these points, the effective uses of alternative material for conventional concrete ingredients are studied. Coconut Shell: Coconut shell is found throughout the tropic and sub-tropic area.. Coconut trees are located among the most common sights throughout the costal areas like Kerala. Various southern states combined account for almost 92% of the total production in the country: Kerala (45.22%), Tamil Nadu (26.56%), Karnataka (10.85%), and Andhra Pradesh (8.93%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining 8.44%.India produces a 10,824,100 tones/year of Coconut. Glass: Glass is mixture of number of metallic silicates. It is one of the most versatile and oldest materials in the building industry. From its humble beginnings as a window pane in luxury houses of Pompeii to sophisticated structural members in new age buildings, its role in architecture has evolved over the years.

the combustion of coal. Fly ash is generally captured from the chimneys of power generation facilities, whereas bottom ash is, as the name suggests, removed from the bottom of the furnace. In the past, fly ash was generally released into the atmosphere via the smoke stack, but pollution control equipment mandated in recent decades now require that it be captured prior to release. It is generally stored on site at most US electric power generation facilities. Depending upon the source and makeup of the coal being burned, the components of the fly ash produced vary considerably, but all fly ash includes substantial amounts of silica (silicon dioxide, SiO2) (both amorphous and crystalline) and lime (calcium oxide, CaO). Fly ash is commonly used to supplement Portland cement in concrete production, where it can bring both technological and economic benefits, and is increasingly finding use in synthesis of geopolymers and zeolites.

Following are the objectives of the research: 1. To study the properties of Coconut shell, Glass and Fly Ash and Concrete Ingredients. 2. Comparative Study between conventional concrete and coconut shell and glass base concrete with the following Tests (For M 30 Grade of Concrete) i) Compression Strength ii) Tensile Test

Problem Statement: Now a day‘s construction of infrastructure and housing increases rapidly in our country. Due to this consumption of cement, coarse aggregate and fine aggregate increases day by day, for manufacturing of these ingredients requires the natural recourses so due to this large amount of utilization natural recourses environmental imbalance takes place, due to this need of alternative materials essentially require to partially replacement of these ingredients. The effective use of natural and artificial waste can be best alternative for cement, coarse and fine aggregate. Methodology: For this research, the following flow of work followed – Step 1- Collection of Fly ash, coconut shell and glass from the adjoining industry glass. Step 3: In this experimental work Fly Ash, coconut shell and glass with different proportion (10 %, 20%) added to concrete mix design for M 30 of concrete and different elements like a cube, cylinders, are casted. Step 4- Experimental work is carried out on cast elements and test results are compared with conventional concrete.

The ingredients of concrete i.e. cement, fine aggregate, coarse aggregate, Fly Ash, glass powder, coconut shells are tested before producing concrete. The respective Indian standard codes are followed for conducting various test on ingredients materials of the concrete. The raw materials used in this experimental work locally available and these included Ordinary Portland Cement (O.P.C) as binding agent, waste glass sand as fine aggregate and coconut shell as coarse aggregate flay ash as cement. Potable tap water was used for mixing and curing throughout the entire casting. The permissible and tolerance limits of water were checked as per the I.S 456-2000.

Cement: - Ordinary Portland cement grade 43, conforming to I.S 12269-2009 was used.

Fly Ash: Following result obtained from fly ash testing in laboratory which is collected Industry.

Coarse aggregate consists of 50% of self-weight of concrete and 70% of volume of concrete. Coconut shells are collected from temples to analyse the properties of coconut shell (2-7 mm thickness.

Glass powder : Waste glass for this experiment was sourced from a glass recycling company‖ Pitroda Pulverizing & Engg Works‖ Bhavani Peth Pune . The company collects mixed colour post-consumer container glass, material to a crushing and milling process in order to create a fine aggregate.

1. For the determination of compressive strength of concrete the mould of size 150x150x150 mm for M30grade of concrete are used It is cured for 3,7& 28 days. 2. For the determination of split tensile strength of concrete the specimen are casted of size 150mm dia.&300 mm ht. for M30grade of concrete are used It is cured for 3,7& 28 days. 3. The necessary precations were taken during casting after 24 hrs all the specimens are demoulded & curing was done under standard conditions.

As per IS 516:1959, test specimens of size 150x150x150 mm were prepared for testing the compressive strength concrete. Fly Ash, coconut shell to concrete mix design for M 30 and different elements like a cube, cylinders, are casted. The rate of applied loading should be 140 kg/ cm2 per minute. In this study, to make concrete, cement and fine aggregate are first mixed dry to uniform colour and then coarse aggregate was added and mixed with the mixture of cement and fine aggregates. Water was then added and the whole mass mixed. The interior surface of the moulds and the base plate were oiled before concrete was placed. After 24 hours the specimens are removed from the moulds and placed in clean fresh water at a temperature of 27ºC. The specimens casted are tested after 3 days, 7 days and 28 days after curing. For testing in compression, no cushioning material was placed between the specimen and the plates of the machine. The load was applied axially without shock till the specimen was crushed. Results of the compressive strength test on concrete are as follow:

Concrete is sufficient in strength only in one direction. The tensile strength of concrete is approximately one-tenth of the compressive strength and it is not generally used in the design of concrete structure. Nevertheless, it is an important property in many applications. The splitting indirect tensile is also known as the Brazil test, which developed originally in Brazil. The testing of specimens in pure tension is very difficult and usually determines by indirect mean, applying tension in the form of splitting. Concrete specimens for indirect tensile test were 150mm diameter and 300mm height. The specimens were placed with its axis horizontal, between the platens of a compression- testing machine. Load was applied until the specimen fails in its vertical diameter. The splitting test is simple to conduct and gives more consistent results than other tension tests. It is believed that the strength obtained by splitting test is near to that of the true tensile strength of the concrete than modulus of rupture. Tensile strength of a concrete is a measure of its ability to resist forces, which stretch or bend it. Unlike steel, the concrete is sufficient in strength only in one direction.

The load shall be applied as per IS. 5816-1999 (reaffirmed 2004) without shock and increased continuously at a nominal rate within the range 1.2 N/ (mm2/min) to 2.4 N/ (mm2/min).Maintain the rate, once adjusted, until failure. On manually controlled machines as failure is approached the loading rate will decrease; at this stage the controls shall be operated to maintain as far as possible the specified loading rate.
