1) Slag concretes developed strength more slowly than OPC concretes at early ages but performed similarly to OPC concrete after 28 days. A hyperbolic model can accurately describe the strength development over time when accounting for curing temperature effects.
2) The addition of blast furnace slag to expansive soils reduces swelling, plasticity, and clay content which mitigates heave.
3) Blast furnace slag can be used as an alternative binder to cement in road construction applications due to its slow setting properties, improving workability during application and long-term strength development.

fly ash and rubber in concrete ( eco-friendly concrete)Koppolu Abishek
This study investigated the effects of partially replacing cement with fly ash and coarse aggregate with rubber chips in concrete. Concrete mixtures were prepared with 0%, 10%, and 20% fly ash replacement of cement and 5% rubber chip replacement of coarse aggregate. Fresh and hardened properties were tested. Test results found that 5% rubber replacement slightly reduced compressive strength compared to normal concrete. However, increasing fly ash content from 10% to 20% improved mechanical properties of the rubberized concrete. Therefore, partial replacement of cement with fly ash and coarse aggregate with rubber chips has potential to produce concrete with comparable strength to normal concrete while utilizing waste materials.
This document summarizes an experimental study on the behavior of concrete with partial replacements of fine aggregate with copper slag and cement with ground granulated blast furnace slag (GGBS). Concrete cubes, cylinders, and prisms were produced with 0-40% fine aggregate replaced by copper slag and 0-20% cement replaced by GGBS. The specimens were tested after 7, 14, and 28 days to determine their compressive, split tensile, and flexural strengths. The results showed that concrete strength generally increased up to 40% fine aggregate replacement by copper slag and 15% cement replacement by GGBS compared to conventional concrete. This study aims to reduce construction costs while promoting sustainable use of industrial byproducts.
Proper mixing, handling, placing, and curing of concrete are essential to producing high-quality concrete, even with a well-designed mix. Inadequate attention to these steps can result in poor concrete. Thorough mixing is needed to fully blend the materials, but overly long mixing provides no benefit and reduces batch plant output. The optimum mixing time depends on factors like the mixer type and size of the load. Fresh concrete properties like workability and compactability greatly influence the hardened concrete's strength and durability.

Experimental Study on High Strength Concrete using Industrial Wastesijtsrd
Generally the river sand is used as a fine aggregate on concrete and is obtained by mining the sand from river bed. Increased sand mining not only affects the aquifer of the river bed but also causes environmental problems. In recent days demand for river sand is increasing due to its lesser availability. Therefore the practice of replacing river sand with Metakaolin is taking a tremendous growth. It is inferred from the literature that replacement of Metakaolin upto 40 gives tremendous increase in the strength of the concrete above which the strength starts to decrease. Various literatures show that replacing with green sand 30 to 40 replacement seems to be effective. In both the cases the workability decreases with the increase in its quantity. Also Bottom ash and Metakaolin replacement results in the decrease of workability and it leads to uneconomic in the project. This paper presents the replacement of fine aggregate up to 40 . The river sand is replaced by Green sand, and Marble powder. The replacement levels of Green sand and marble powder varies from 5 , 10 , 15 and 20 . From the mix design, the w c ratio is taken to be 0.40. The specimens are to be casted, cured for the respective mix proportions and various strength characteristics of the concrete at 28 days are to be performed. The suitability of the replacement materials as fine aggregate for concrete has been assessed by comparing its strength.

The document studies soil cement blocks used for load-bearing masonry. Soil cement blocks with varying cement contents (6%, 8%, 12%) were tested to examine characteristics like compressive strength, water absorption, pore size, and elastic properties. Testing found that doubling the cement content from 6% resulted in over 2.5 times increase in strength. Water absorption was not greatly affected by cement content, but rate of absorption and pore size decreased with higher cement. Elastic modulus increased over 2 times when cement increased from 6% to 8%, but only marginally from 8% to 12%. The study aims to promote soil cement blocks as a lower-cost and more sustainable alternative to fired clay bricks for housing construction.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
