ABSTRACT Our projects deal with experimental study on Flyash and metakaolin. Cement production currently constitutes the fourth largest source of carbon emissions. As these emissions continue to rise, the natural world faces the threat of a hazardous environmental pollution. Flyash, an innovative binding compound, presents a carbon- negative alternative to cement that utilizes a variety of waste streams to produce a versatile building material. Life Cycle Analysis (LCA) is used from a cradle-to-gate perspective to compare the environmental impacts of Flyash and Ordinary Portland Cement (OPC), focusing specifically on their contribution to carbon pollution, water use and energy consumption. Keywords: Flyash, Life Cycle Analysis, metakaolin , carbon negative, recycled by-product.

INTRODUCTION
Concrete is the commonly used building material and it is a key structural material in human history. Concrete is a brittle material composed of fine and coarse aggregate, cement and water which are embedded in a hard matrix. Usage of concrete is mainly due to economy, versatility and adaptability. Moreover workability is more important parameter of concrete and it is necessary to achieve workable concrete by improving the compaction and placing homogenously without segregation and bleeding. With the advent of cement as the binding material, the field of concrete technology has seen a tremendous growth. The ingredients of concrete have been supplemented with admixtures, Supplementary Cementitious Materials (SCMs) and other chemicals to attain certain desirable qualities in it. One such quality is compressive strength, by means of proper proportioning of these components or additions, compressive strength values up the order of 120 MPa can be achieved. The next important durability property is considered to be the most essential requirement of concrete. Several materials and methods have helped in achieving the desired durability characteristics. The subsequent development of specialized concretes such as high strength concrete, high performance concrete, no-fines concrete, Fiber Reinforced Concrete (FRC), ferro-cement concrete, gap graded concrete, high density concrete, nuclear concrete, heat resisting and refractory concrete, Self-Compacting Concrete (SCC), geo-polymer concrete, etc., over a period of time is a clear depiction of the advancements in the field of concrete technology. Concrete that suits extreme environmental conditions is required for enhancing durability. The use of waste materials, which possess pozzolanic properties in concrete has enabled researchers alike to bring about sustainability. SCC, which is a flowing concrete, also makes use of these materials in a beneficial way and SCMs help in increasing the powder content in it. Use of High Range Water Reducing Agents (HRWRAs) is useful by way of improving the workability characteristic of concrete mixes. Concrete is tailored to meet the growing demands in several diversified applications. State of the art technologies in making specialized concrete are made possible due to the research activities carried out in all parts of the world. Also, these research findings are brought into application and they pave the way for revisions in the provisions of codes from time to time.
