Abstract - The technology for mixed concrete is currently
advancing quickly, and numerous additional materials are being applied to create concrete with the required properties. Adding a chemical, like an entraining additive, or reducing water in the form of synthetic or organic materials is one method to enhance the quality of the concrete mix. In order to determine the ideal amount of bio-enzyme in concrete to boost its strength, bio-enzyme is added to five concrete mixtures that will be compared to regular concrete. Concrete mixes M30, M35, and M40 will be made with bioenzyme 500 ml/�3, 600 ml/�3, 650 ml/�3 & GGBS of 5% to 15% as part of the current investigation. Compression, split tensile, and workability tests will be conducted.
Every potential way to reduce CO2 emissions is being explored in this period of massive global warming, and one of the main emissions occurs during the cement-making process. Many materials, including fly ash, GGBS, silica fume, wollastonite, and waste glass powder, are utilized in place of some cement in order to address this issue. Environmental pollution can be decreased by partially substituting ground granulated blast furnace slag for cement.

1. INTRODUCTION
Portland cement is commonly regarded as the main component of concrete, which is among the most frequently utilized construction materials. The widespread use of concrete as a building material is driven by the infrastructure advancements resulting from rampant urbanization and industrial development. Cement production is expected to grow from around 1.5 billion tons in 1995 to 2.5 billion tons by 2015. Globally, concrete is utilized in the construction of highways, bridges, buildings, runways, sidewalks, and dams. Given the necessity of cement in construction, it has a strong connection to the economy. Projections indicate that cement production will rise from 2.55 billion tons in 2006 to between 3.7 and 4.4 billion tons by 2050, reflecting an annual growth rate of 2.5 percent.

GGBS (Ground Granulated Blast-furnace Slag) is recognized as one of the environmentally friendly construction materials. Its raw material is a very particular slag that is a byproduct from the process of manufacturing iron in blast furnaces. The production of GGBS makes use of all the slag and generates no significant waste stream. Ground Granulated Blast-furnace Slag is a cement-like substance primarily utilized in concrete and is a byproduct from the operation of blast furnaces that produce iron. The rapid cooling enhances the cementitious characteristics and results in granules resembling coarse sand. This granulated slag is then dried and milled into a fine powder.

1.1 Bio-Enzyme
vegetable extracts, enzymes improve the engineering properties of the soil . Bio Enzyme, often referred to as Garbage Enzyme or Fruit Enzyme, is a versatile natural cleaner created from waste or the peels of fruits and vegetables, mainly citrus. Terrazyme is an alternative designation for it. From a chemical perspective, the bio-enzymes consist of a combination of complex organic compounds, such as proteins, salts, and other naturally occurring substances produced by the bacteria or yeast that we will utilize to produce them. Bio-enzymes are organic, biodegradable materials that are applied as additives to enhance soil. A liquid extract obtained from fruits and vegetables, bioenzyme is organic in composition. It enhances the strength and durability of concrete. Dr. Rosukun Poompanvong is involved in bio-enzyme research and development in Thailand.

Using hydrochloric acid (HCL) in concrete durability testing is part of acid resistance testing, which evaluates how concrete withstands aggressive chemical environments-especially relevant for industrial floors, sewage systems, or chemical plants. Concrete is alkaline in nature due to calcium hydroxide (Ca(OH)₂) and other hydration products. Acids like
