Population development has been further developed, providing enormous requirements for increasing scaffolding. This demand results in increased cement production. The huge amount of luxury materials is provided by the production of companies such as silica exhaust, rice scale feeders, mineral slag and more. As a result, waste management has had a major problem with our environment. Economically important bagasse, molasses and channel press mud. Bagasse is a thread-shaped structure that remains as sugar cane is extracted. The sugar pipe bag consists of about 50% of cellulose, 25% of hemicellulose, and 25% of lignin. In the sugarcane industry package, the produced bagos is usually used as fuel, reducing its volume for transmission at the same time. One of the residues from the tobacco production line is tobacco stems, which are easy to collect when that generation is concentrated on the tobacco production line. This is driven by a true waste of resources and natural topics, as more than 95% of landfills and burned cigarettes have reached conclusions. Tobacco is created by burning these unwanted tobacco tribes. The exploration of the study here negotiates half the substitution of the combination by mass with SBA at the rate of 3%, 6%, 9%, 12%, and 15%, and at the combination of 3%, 6%, 9%, and 12%. After mixing, the characteristic quality of this new concrete is compared to the everyday concrete of the M30. Exploratory studies are carried out for print quality, sometimes flexible quality, and bending strength over 7, 14, and 28 days of cure time. The experiments suggest that the combination of a 21% exchange rate, including 12% SBA and 9% TWA, had higher values for print quality, bending strength and partial poison quality compared to other replacement processes.
Introduction
This study focuses on reducing the environmental impact of concrete production by partially replacing cement with Sugarcane Bagasse Ash (SBA) and Tobacco Waste Ash (TWA), both industrial by-products with potential pozzolanic properties.
Environmental Motivation:
Cement production contributes significantly to global CO? emissions.
SCMs (Supplementary Cementitious Materials) like SBA and TWA offer a sustainable alternative, improving concrete properties while reducing cement use and environmental burden.
Materials Used:
Class 53 Ordinary Portland Cement (OPC)
Fine and coarse aggregates (as per IS standards)
SBA and TWA as partial cement replacements
Water and superplasticizer (Conplast WL Xtra)
Experimental Design:
M30 grade concrete mixes were prepared using:
SBA at 3%, 6%, 9%, 12%, 15%
Then, with 12% SBA fixed, TWA was added at 3%, 6%, 9%, 12%
Mix proportion: 1:1.99:3.47 with a water-cement ratio of 0.42
Key Findings (28-Day Strengths):
SBA Alone:
Optimal replacement at 12% SBA
Compressive strength: 41.96 MPa (13.03% ↑ vs. control)
Tensile strength: 4.69 MPa (9.57% ↑)
Flexural strength: 7.42 MPa (13.62% ↑)
SBA + TWA:
Best performance at 12% SBA + 9% TWA
Compressive strength: 42.92 MPa (15.62% ↑)
Tensile strength: 5.38 MPa (25.70% ↑)
Flexural strength: 7.81 MPa (19.60% ↑)
Conclusion:
Replacing cement with SBA and TWA enhances concrete’s mechanical properties.
Optimum performance is achieved at 12% SBA and 9% TWA, making it a viable eco-friendly alternative for conventional cement in M30 concrete.

Conclusion
Based on the above research, the following analysis was carried out on artificial concrete in which cement was partially replaced with SBA and the mineral additive TWA.
1) As the SBA & TWA ratio in the Concrete changes, its workability decreases.
2) It was found that the maximum strength in the total percentage of cement modified with Sugarcane Bagasse ash occurred at 12%SBA.
3) Compared to other mixtures, the highest concrete properties were obtained with concrete mixtures containing 12%Sugarcane Bagasse ashand9%TWA.
4) According to the test results, it was determined that the strength of the concrete combined with Sugarcane Bagasse ash and Tobacco Waste ash increased better than the SBA concrete mixture.
5) It is seen that the use of 12%Sugarcane Bagasse ashincreases the compressive strength by 13.03%, splitting tensile strength by 9.57% and bending strength by 13.62% compared to conventional concrete.
6) Compared to normal concrete, it is seen that the use of 12%Sugarcane Bagasse ash and 9%Tobacco Waste ash increases the compressive strength by 15.62%, splitting tensile strength by 25.70% and bending strength by 19.60%.
