As we know everything is 2. OBJECTIVE dependent on nature, and as a civil engineer we know that soil plays a vital role in construction. When we erect any structure over the We do this experiment to enhance the quality of soil by soil, firstly we check the behavior and attribute of soil that how much strength is present in the soil so that it can bear structure load which mixing the wheat husk ash. Wheat husk ash is effectively will be erected over this soil. There are several types of soil which accessible at farming field. In think about of different have different- different qualities, some soils have greater strength strategies this techniques is more compelling, monetarily and some have lower, if the strength of soil is lower than our modest and effectively accessible. We utilize fine parts of requirement then we constrained to increase the strength of the soil wheat husk ash to enhance the quality of soil it is useful for as per our structure requirement. In this research paper we the earth and they are no hurtful substance introduce in the performed various test on soil to know its properties or strength by wheat husk ash. wheat husk ash directs the porousness of soil, using agricultural waste material such as wheat husk ash (WHA) as a increment the quality of soil keep up dryness and so on. stabilized material in soil with varying percentages 0%, 3%, 5%, 7%,9% . 1.1 To investigate the possibility of utilizing agriculture waste materials like Wheat husk ash (WHA) in soil stabilization. Keywords: WHA, SPT, CBR, UCS 1.2 To discover the physical and designing properties of natural soil and balanced out soil by replacing 0%, 3%, 5%, 7% and 9% of 1. INTRODUCTION soil with wheat husk ash. The highest fringe layer of earth in which dull or diminish 3. MATERIAL darker material generally comprised of a mix of normal remains mud and shakes particles. Exchange of strong waste 3.1 Natural Soil on the landfill can be compelled if the waste is having Fine sand is found in inexhaustible in western Rajasthan. The engaging properties to such an extent, to the point that they sand used as a part of current research was brought from can be used for different geotechnical application viz. arrive construction site at Jaipur. Fine sand is uniform clean sand as recovery, headway of embankment and so forth. Soil per Unified Soil Classification System. Particles measure stabilization is the framework which is utilized to enhance the keeps running between 75μ to 1.0 mm i.e. fine coarse sand, engineering properties of the earth and consequently making round to exact perfectly healthy as indicated by Indian everything the more steady. Soil stabilization is required when Standard Classification System. the earth accessible for development isn't sensible for the ordinary reason. It wires compaction, pre-consolidation, 3.2 Wheat Husk Ash(WHA) spillage and different other such frameworks. There are several frameworks utilized for updating geotechnical WHA has a decent pozzolanic property. It is utilized for properties of questionable soils that wires densification, (for different purposes. It is the staple nourishment delivered in example shallow compaction, dynamic significant expansive amount for living and non-living creatures. It has compaction, pre-stacking), leakage, contemplations, (for high calorific estimation of around 3.5 kcal/g. Its result is example, geosynthetics and stone areas), and alterations. For frequently found in the fields since waste is scorched by the instance, wheat husk is solid waste from farming field which farmer subsequent to extricating grains. In this study, the is additionally causes disposal issue for the civil engineer so impact of WHA on the soil is contemplated. Wheat husk is the fundamental intention of this research is to diminish the taken from the agriculture fields and consumed at 600°C to disposal issue of such sort of material by using this waste change over into fine ash remains. This wheat husk ash has material in fluctuating rates in the dirt to upgrade the building most astounding measure of silica which helps in fruitfulness properties of the dirt. of soil. Wheat husk ash, essentially a waste material, is created 32 Vikas Sharma, Pramod Kumar Rathore and Amit Sharma by burning crop waste while handling wheat from paddy. compressive quality were completed as per IS: 2720 (section Around 20 – 22% wheat husk is created from paddy and 10) – 1991, Methods of test for soils: Determination of around 25% of this aggregate husk progress toward becoming Unconfined compressive strength. cinder when consume. It is non – plastic in nature. Its 4.3.1 Stage First : Properties of soil – In first stage there are properties additionally fluctuated relying upon its consuming various properties such as structure, texture, consistency, bulk temperature. density, permeability, plastic limit, and shrinkage limit The chemical properties of WHA are shown in Table 1 Table 1 Chemical Properties of Wha At 600 °C 4.3.2 Stage second: - Experiment procedure – Specific Gravity by pycnometer: The specific gravity of a dirt Sr. No. Compound Value(%) is utilized as a part of the stage relationship of air, water, and 1 Silicon Oxide (SiO2) 42.33 solids in a given volume of the dirt.

METHODOLOGY 4.1 Sample Preparation: The sample for testing was set up as per the requirements of the tests. The soil sample was first sieved through the appropriate strainer for a respective test. The required quantum of soil was weighed out for the test. The wheat husk ash to be added to the soil was similarly sieved through the required strainer, for the particular test and a while later the required quantum was weighed out and added to the earth for Fig. 1: Pycnometer Test Apparatus test. The soil and the wheat husk ash were then mixed in dry state before testing. The blend sample was then used for Grain Size Distribution The grain size distribution is broadly used performing out the distinctive tests. for the categorization of soils. The information gain from grain size 4.2 Index Properties distribution curve is utilized for the design of filter for earthen dams and to decide suitability of soil for pavement development, landing Index properties are the simple physical properties of the soils, strip and so on. Data acquired from grain size distribution analysis which are used for classification of soils for various can be used to foresee soil water advancement regardless of the way engineering applications. They indicate a qualitative behavior that vulnerability tests are all the more all things considered used. of soil when subjected to various types of load. The Specific Gravity (Gs) of the soil examples was decided according to May be: 2720 (section 3/Sec1) – 1980, Methods of test for soils: Determination of Specific Gravity, fine grained soils. The mud and residue estimated divisions of the dirt example was resolved according to May be: 2720 (section 4) - 1985, Strategies for test for soils: Grain measure examination. Atterberg's points of confinement of the dirt example was resolved according to May be: 2720 (section 5) – 1985, Methods. 4.3 Engineering Properties Engineering properties of soils are those properties which can be utilized for measuring the Engineering behavior of soils.
