Sedimentary rocks
This document summarizes key information about sedimentary rocks, including their formation processes (mechanical, organic, chemical), structural features (stratification, lamination, cross-bedding), and common types (limestone, sandstone, shale, laterite). Sedimentary rocks form from the deposition and consolidation of sediments and make up 70-80% of the Earth's surface. Their formation involves compaction, cementation, and crystallization. Structural features provide clues to depositional environments. Common types are described along with their compositions and uses.
Stratified rocks
Stratified rocks are formed from layers of sediment or volcanic material that build up over time. The layers can range significantly in thickness from millimeters to meters and come in different shapes. Examples of stratified rocks include sedimentary rocks with clear layering as well as some igneous rocks, such as granite, that form distinct layers when they cool and harden on the Earth's surface.
Classification of Igneous rocks
This document summarizes how rocks are classified based on their formation. There are three main classes of rocks: igneous, sedimentary, and metamorphic. Within each class, rocks can be further classified based on their composition, texture, and grain size. Igneous rocks form from cooled lava or magma, and can be intrusive or extrusive based on where they solidify underground or above ground, affecting their grain size. Sedimentary rocks form from cemented sediments like grains, shells, and fossils. Metamorphic rocks have foliated or non-foliated textures indicating the process that altered the original rock.
GI For Tunnel Projects
This document discusses ground investigation for tunnelling projects. It covers objectives of ground investigation planning including suitability assessment, design, construction planning and environmental impact determination. Key risks like water ingress, ground collapse and obstructions are highlighted. Common ground conditions like dykes, wedges and timber piles are shown. Strategies and techniques for ground investigation planning, during design and construction stages are outlined. Methods for different ground types like soft ground, hard rock and karst deposits are also described. The document emphasizes comprehensive planning and supervision of ground investigation works for tunnelling projects.
Structures of sedimentary rocks
Sedimentary rocks form through the deposition of sediments or fragments by processes like erosion, transportation, and deposition. Sedimentary structures are classified based on how the sediments were deposited and include stratification, graded bedding, cross-bedding, ripple marks, mud cracks, rain drop marks, casts and molds, tool marks, tracks and trails, and burrow marks. Sedimentary rocks also include chemical rocks like limestone and dolomite formed from mineral precipitation, and biochemical rocks like coal and fossil-bearing limestone formed from organic materials.

Introduction to Cement
This slideset was prepared as a student group assignment, for a class on-Introduction to Construction Materials. The facts shown and data used are most relevant to the Indian Context. Prepared by- K. Hari Chandana, Sukirti Sah, Tanya Talwar, Rana Sarkar, Akriti Srivastava, Jitendriya Meher, Anshuman Abhisek Mishra : 1st Sem B. Arch, School of Planning & Architecture, Bhopal, MP, India
Rock Types
The document describes three main types of rocks:
1) Igneous rocks form when magma cools and solidifies, either deep underground or at the surface. Examples are granite, basalt, and obsidian.
2) Sedimentary rocks form from compression of sediments and contain layers and fossils. Examples are limestone, sandstone, and shale.
3) Metamorphic rocks form from changes to existing rocks through heat, pressure, and reaction with fluids. Examples are marble, slate, and gneiss.
Manifestation and remediation of alkali aggregate reaction
The document discusses alkali aggregate reaction (AAR), which occurs when highly alkaline cement reacts with certain aggregates containing silica or carbonate minerals. This can cause expansion and cracking of concrete. The two main types are alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR). ASR was first identified in California in the 1930s and has caused damage in structures worldwide. Remediation methods include using low-alkali cement, avoiding reactive aggregates, controlling moisture, and treating affected concrete with lithium compounds which can stop further ASR cracking.
Types of rock gr. 6
Rocks are naturally occurring mixtures of minerals, glass, or organic matter that are divided into three main types based on their formation: igneous, sedimentary, and metamorphic. Igneous rocks form from cooling magma or lava. Sedimentary rocks form through the compaction or cementation of sediments. Metamorphic rocks form from existing igneous or sedimentary rocks that have been changed by heat, pressure, and chemical reactions in Earth's crust. Rocks can change between these types through geological processes in a continuous cycle.
stone ppt
This document discusses building stones used for construction. It defines building stones as those suitable for structures like retaining walls, abutments, dams, and roads. Building stones must have strength and durability. Stones are classified as igneous, sedimentary, or metamorphic based on their formation. Common building stones include marble, granite, sandstone, limestone, chalk and laterite. Properties like hardness and durability depend on a stone's mineral composition and resistance to weathering. Stones are obtained from rocks through quarrying and are used in construction in various forms such as rubble, dimension stone, flagstone and crushed stone.
Three Types of Rocks
There are three main types of rocks: sedimentary, igneous, and metamorphic. Sedimentary rocks form from the accumulation of sediments or organic matter. Igneous rocks form from the cooling of molten rock material either below or above the Earth's surface. Metamorphic rocks were once sedimentary or igneous rocks that were altered by heat, pressure, and chemical processes underground.

STONE -As A Building Material.
Stones have been considered as one of the popular building material from the olden days due to their availability in abundance from the natural rocks. Building stones should possess enough strength and durability.
The stones which are suitable for the construction of the structures such as retaining walls, abutments, dams, barrages, roads etc are known as building stones. Engineering Geology (Civil Engineering Applications)
This document discusses the important geological factors to consider when selecting sites for dams and reservoirs. Narrow river valleys, shallow bedrock, and competent bedrock foundations are desirable for reducing dam construction costs. Sedimentary rocks like sandstone and limestone can cause water leakage from reservoirs depending on their porosity. Metamorphic rocks like gneiss and quartzite are generally impermeable. Geological structures must also be considered, with horizontal or tilted strata being most suitable and faults or intense fracturing making a site undesirable. The document outlines these considerations in detail.
Gravity dam
Gravity dams are structures designed so that their own weight resists external forces. Concrete is the preferred material. Forces acting on the dam include water pressure, uplift pressure, earthquake forces, silt pressure, wave pressure, and ice pressure. The dam's weight counters these forces. Dams are checked when full and empty, accounting for load combinations. Gravity dams can fail due to overturning, crushing, tension cracks, or sliding along foundation planes. Design aims to prevent failure from these modes.
Stones
This document provides information about building stones used in construction. It discusses the characteristics of good building stones, including hardness, durability, porosity, decomposition and others. It also describes common uses of building stones and various tests conducted to examine stones, such as crushing, weathering, porosity, attrition and others. Finally, it discusses quarrying, dressing, classification and deterioration of stones.

Applications of artificial Intelligence in Mechanical Engineering.pdf
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.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Embedded machine learning-based road conditions and driving behavior monitoring
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.
