Bio cement, derived from microbial-induced calcium carbonate precipitation, offers potential benefits such as self-healing properties and increased durability. Alccofine1203, a high-performance superplasticizer, is known for its ability to improve the workability and strength characteristics of concrete. In this research, various mixes of concrete incorporating different proportions of bio cement and Alccofine1203 are prepared and tested for compressive and split tensile strength. The experimental results are analyzed to assess the influence of bio cement and Alccofine1203 on the mechanical and durability properties of concrete at 28, 56, and 90 days. The findings of this study contribute to understanding the synergistic effects of bio cement and Alccofine1203 in enhancing concrete performance, providing valuable insights for sustainable and durable construction practices. Key words: Bio cement, Alccofine 1203, Enhancing , Microbial-induced, Compressive strength and Split tensile strength
1. INTRODUCTION Concrete is among the most extensively utilized construction materials worldwide; however, its production poses substantial environmental challenges, primarily due to the significant carbon emissions linked to the manufacturing of ordinary Portland cement (OPC). This study explores the use of bio-cement and Alccofine 1203 as supplementary cementitious materials to create a more sustainable and efficient concrete mix. Bio-Cement: Bio-cement, produced through microbial processes, is a groundbreaking material that employs microorganisms to precipitate calcium carbonate. This method, known as

potential to lower the carbon footprint of concrete production while improving its mechanical and durability characteristics. Bio-cement has garnered interest for its capacity to enhance the binding properties of concrete and increase its resistance to environmental degradation. Alccofine1203: Alccofine 1203 is an ultrafine slag-based supplementary cementitious material that improves concrete performance by enhancing workability, strength, and durability. Its ultra-fine particles and distinctive size distribution promote better dispersion within the mix, leading to a denser concrete matrix and reduced permeability
2. OBJECTIVES 1. Evaluate the effects of incorporating bio-cement and Alccofine 1203 on the compressive and tensile strength of concrete, aiming to determine the optimal proportions of these materials for improved mechanical performance. 2.Investigate the durability properties, including resistance to sulfate attack, chloride penetration, and ater permeability, while assessing the environmental advantages, such as carbon footprint reduction and resource efficiency, associated with using bio-cement and Alccofine 1203 in concrete.
3. MATERIALS 3.1 Cement: Cement is a finely ground powder composed of clay, limestone, and other minerals that undergoes a chemical reaction called hydration when mixed with water, forming a solid binding material. As the key ingredient in concrete, it provides structural stability and strength. However, its production is highly energyintensive and generates substantial carbon dioxide emissions, highlighting the need to explore sustainable
