Abstract - Designing a structure on clay or Red clay is the
engineers. In fact of view these clays show an enormous change in bearing capacity while in contact with water. Climatic conditions of the city also facilitate the same, During the summer(April & May) city records the maximum temperature 108oF and an average temperature of 1030F at the same time the rainfall in those months will be 20% (April - 43.6mm & May - 55.2mm) of annual rainfall (499.5mm) of the city. Due to this change in the climatic condition clay also shrinks and swells with short duration. The main aim of this laboratory investigation is to study the effect of the inclusion of Recron-3S powder (PR3) supplement on the enhancement of shear strength parameters of Red clay soil samples collected from the south part of coimbatore city. The laboratory investigation was performed on the compacted soil specimens with 1%, 2%, 3%, and 4% Recron-3S powder (PR3) and results of compaction, unconfined compression, and California Bearing Ratio (CBR) tests are discussed.
most difficult task for civil engineers as well as geotechnical engineers due to its swelling effects, enormous change in shear strength, and settlement while in contact with water. To make those clays capable of more bearing soil, a special method of stabilization must be adopted to improve the bearing capacity of the soil. In that regards this paper grants a laboratory study of the effect of powdered Recron3S(PR3) on the shear strength parameters of Red clay. Soil samples were collected around the Coimbatore region. In the first stage of the laboratory study the effect of powdered Recron-3S(PR3)on Red Clay at optimum moisture content with various proportions of PR3 incorporation. The compaction tests have been carried out on the sample of red clay collected on the Coimbatore region with 1%, 2%, 3%, and 4% inclusion of Recron-3S powder(PR3) by weight of the red clay and the RRP3 (Red clay and Recron-3S Powder ) samples have been prepared at the standard optimum moisture content. The Second Stage of a laboratory study on the main focal point of observing shear strength parameters like unconfined compression strength and maximum dry density of natural red clay and combination with PR3 samples. At the end of the laboratory study, it concluded that the inclusion of PR3 on Red clay soil be an effective method for improving the shear strength parameter of the Red clay.
II. OBJETIVES This experimental study is mainly focused to get a clear idea about the improvement in shear strength of red clay available near coimbatore and also observe the behavior of red clay while added with the powdered Recron-3S. The broad Ares includes:
Key Words: Red clay, Recron-3S powder,PR3, RRP3, Compaction tests, Optimum Moisture Content, and shear strength parameter of the Red clay.

III.METHODOLOGY
Coimbatore is one of the cities in Tamilnadu, India. The city has a huge population. As a need in of population. Engineers were forced to construct different types of structures throughout the city. But, the geological feature of the city does not have a soil profile to bear those structures, Because Loamy soil, Red Clayey soil, and Calcareous black cotton soil profile were generally found all around the city, and 50% of the city cover up with Red Clayey soil and black cotton soil. Constructing any civil structure on this type of soil is a difficult task for
