Concrete is described as the founding partner of modern society. A modern society demands schools, offices, recreational spaces, and transportation, which require large structures that are more feasible to construct using concrete rather than mud. Concrete is the most used construction material but cracks are inevitable; self-healing concrete is introduced as a viable method to autonomously heal cracks. Green concrete incorporates recycled waste materials and has environmental and cost benefits over conventional concrete. Statistics show concrete structures have lower emissions and energy usage than other materials like mud, and provide better seismic performance. Prefabricated concrete allows faster construction at larger scales.

The extensive use of concrete as a structural material for the high rise buildings, storage tanks, nuclear reactors and
pressure vessels increase the risk of concrete being exposed to high temperatures. This has led to a demand to improve
the understanding of the effect of temperature on concrete. The behavior of concrete exposed to high temperature is a
result of many factors including the exposed environment and constituent materials.
Concrete structures are exposed to fire when a fire accident occurs. Damage in concrete structures due to fire depends
to a great extent on the intensity and duration of fire. The distress in concrete manifests in the form of cracking and
spalling of concrete surface.

The value of concrete in present society cannot be underestimated. We can see concrete structures everywhere, such as buildings, roads, bridges, and dams. There is no escaping the impact concrete makes on your everyday life. Concrete is a composite material which is made up of filler and a binder. Typical concrete is a mixture of fine aggregate sand , coarse aggregate rock , cement, and water. Cement and lime are usually used as binding materials, while the sand binder is mixed as fine aggregates and crushed stones, gravel, broken bricks clinker is employed as coarse aggregates. The concrete having cement, sand and coarse aggregates mix up in an appropriate percentage in addition to water is called cement concrete. In this kind of concrete, cement is used as a binding substance, sand as fine aggregates and gravel, crushed stones as coarse aggregates.An investigation relating to the use of byproducts to enhance the functions of concrete has been about for many years. In the recent years, the researchers have been made to use industry by products such as fly ash, silica fume, ground granulated blast furnace slag, glass cullet, etc., in concrete production and civil applications. The potential uses of industrial byproducts in concrete or as a partial aggregate substitution or as a partial cement substitution depending on their chemical composition and grain size, The utilization of these materials in concrete comes from the environmental constraints in the safe disposal of these products. Big interest is being focused on the environment and safeguarding of natural resources and recycling of waste materials. Various industries are producing a significant number of products which incorporate residues such as reclaimed aggregates, reclaimed asphalt pavement, foundry sand, copper slag, fly ash, glass cullet, polyethylene terephthalate, high density polyethylene HDPE , unplasticized polyvinyl chloride UPVC , plasticized polyvinyl chloride PPVC , low density polyethylene LDPE , polypropylene PP , polystyrene PS , expanded polystyrene UPS .

For each ton of Cement produced, one ton of CO2, a greenhouse gas, is released into the atmosphere. Worldwide, the Cement industry produced about 1.4 billion tons in 1995, which caused the emission of as much CO2 gas as 300 million automobiles. Our industry has a responsibility and societal duty to make a contribution towards taking the steps necessary to achieve sustainable development. A scientific approach towards conserving natural resources involves increasing durability of structures, because more durable structures need to be replaced less frequently. Such increased durability can be achieved by choosing appropriate mix designs and selecting suitable Aggregates and admixtures. Development of Engineered Cementitious Composite (ECC) materials using High volume of Fly Ash and Polyvinyl Alcohol (PVA) fibers will produce the most promising construction materials with High durability. This Paper focuses on Development and study of Engineered Cementitious Composites using High Volume Fly Ash and Polyvinyl Alcohol Fiber, the use of which will increase the durability and hence lead to the Sustainable Development in Construction Industry

The key properties of SCC include high flowability, passing ability, and segregation resistance. These properties are achieved through optimizing the mix design, including using a high range of superplasticizer, limiting coarse aggregate content, increasing fine particles and viscosity modifying agents. SCC has applications in structures with dense reinforcement like the Burj Khalifa where it simplified construction. The document also discusses experimental investigations into the compressive strength of SCC exposed to
Development of high-strength, economical self-consolidating concrete
Naık T. R. , Kumar R., Ramme B. W. , Canpolat F.
This paper presents information regarding development, properties, and advantages and disadvantages of using high-strength self-consolidating concrete in the construction industry. It also presents results of a study recently completed for manufacturing economical high-strength self-consolidating concrete containing high-volumes of fly ash. In this study, portland cement was replaced by Class C fly ash in the range of 35-55% by the mass of cement. The results of fresh and hardened properties of concrete show that the use of high-volumes of Class C fly ash in self-consolidating concrete reduces the requirements for superplasticizer (HRWRA) and viscosity modifying agent (VMA) compared with the normal dosage for such admixtures in self-Consolidating concrete. The results further indicate that economical self-consolidating concrete with 28-day strengths up to 62 MPa can be made using high-volumes of fly ash. Such concretes can be used for a wide range of applications from cast-in-place to precast concrete construction.

Effect of Steel Slag as Partial Replacement of Cement on Property of Concrete
A well maintained infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements is challenging. Concrete as a construction material is in use for several decades. Concrete can withstand the severest environments and engineers are constantly trying to improve its performance with the aid of modern admixtures and waste materials with or without cementious properties. The use of waste material in concrete helps to consume these waste materials and also improves the properties of concrete in fresh and hydrated states.Civil structures are designed considering the target compressive strength of the concrete. Although, few other parameters such as workability, water to cement ratio, setting time of cement and surface hardness influence the performance of concrete.In the present research a series of experiments had been performed to compare the use of Steel Slag as partial replacement of cement in different proportions. Concrete mixes are modified by 5 10 , 15 , 20 and 25 of Steel Slag as replacement of cement.The main conclusions drawn are inclusion of Steel Slag increases the compressive strength up to a certain proportion and then reduces the strength. Steel powder increases the strength but reduces the workability. Comparatively higher early strength gain 3 days, 14 days, 28 days is obtained with Steel Slag concrete.

The document summarizes a seminar presentation on green concrete. Green concrete uses less energy in production and produces less carbon dioxide than traditional concrete by utilizing industrial waste and recycled materials. It provides environmental benefits such as longer lifespan, reduced energy consumption and lower carbon emissions. Green concrete can be produced using ceramic waste as aggregates and fly ash or microsilica to replace some cement. This makes concrete production more sustainable while improving properties such as strength, durability and heat resistance. Although higher initial costs are a limitation, green concrete has growing potential in India to reduce environmental impact of the concrete industry.

Effect of Steel Slag as Partial Replacement of Cement on Property of Concrete
A well maintained infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements is challenging. Concrete as a construction material is in use for several decades. Concrete can withstand the severest environments and engineers are constantly trying to improve its performance with the aid of modern admixtures and waste materials with or without cementious properties. The use of waste material in concrete helps to consume these waste materials and also improves the properties of concrete in fresh and hydrated states.Civil structures are designed considering the target compressive strength of the concrete. Although, few other parameters such as workability, water to cement ratio, setting time of cement and surface hardness influence the performance of concrete.In the present research a series of experiments had been performed to compare the use of Steel Slag as partial replacement of cement in different proportions. Concrete mixes are modified by 5 10 , 15 , 20 and 25 of Steel Slag as replacement of cement.The main conclusions drawn are inclusion of Steel Slag increases the compressive strength up to a certain proportion and then reduces the strength. Steel powder increases the strength but reduces the workability. Comparatively higher early strength gain 3 days, 14 days, 28 days is obtained with Steel Slag concrete.

The document summarizes a seminar presentation on green concrete. Green concrete uses less energy in production and produces less carbon dioxide than traditional concrete by utilizing industrial waste and recycled materials. It provides environmental benefits such as longer lifespan, reduced energy consumption and lower carbon emissions. Green concrete can be produced using ceramic waste as aggregates and fly ash or microsilica to replace some cement. This makes concrete production more sustainable while improving properties such as strength, durability and heat resistance. Although higher initial costs are a limitation, green concrete has growing potential in India to reduce environmental impact of the concrete industry.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

MUD Futures Concrete vs Mud.pptx
- 1. CONCRETE: THE FOUNDING PARTNER OF TODAY’S MODERN SOCIETY
- 2. WHAT IS A MODERN SOCIETY • Looking at the growing population, increasing the building height vertically is the need of the hour. • Wherever it is feasible the ground coverage must be minimum. • A modern society demands: schools, offices, playgrounds, recreational spaces, transportation, and other important amenities.
- 3. Large span structures are more feasible with CONCRETE as compared to MUD
- 4. WHAT IS SELF-HEALING CONCRETE • Concrete is the most often used construction material. Fractures are inevitable because concrete is fragile in tension yet strong in compression. When concrete cracks form, the concrete's lifespan may be diminished. • Microcracks and pores in concrete are unwelcome because they provide an open route for water and other hazardous elements to enter, resulting in reinforcement corrosion and a decrease in the concrete's strength and durability. • Self-Healing Concrete is a viable method for healing concrete cracks on its own. • Because it is bio-based, ecologically friendly, cost-effective, and long-lasting, this bacterial remediation method surpasses others How does Self Healing Concrete works
- 5. WHAT IS GREEN CONCRETE • Manufactured from environmentally friendly waste materials. • It incorporates at least one waste component, such as demolition waste aggregate, recycled concrete aggregate, blast furnace slag, manufactured sand, glass aggregate, and fly ash. • The goal is to create a form of concrete that incorporates as many recycled elements as possible and leaves the smallest carbon footprint possible. • Green concrete is cost-effective to produce since it is built entirely of recycled materials and lowers energy use while enhancing strength and durability. Green Concrete following 3R
- 6. COMPOSITION / MIX DESIGN OF GREEN CONCRETE Table. : Potential elements replacing cement in concrete
- 7. EMISSION AND ENERGY STATISTICS OF VARIOUS MATERIALS Table: Comparative analysis of energy consumption and carbon dioxide emission of four types of building material
- 8. Due to weathering MUD structures get damped and due to this frequent change of weather they develop crack and require frequent maintenance as compared to CONCRETE structures which have higher material integrity
- 9. BUILDING LIFECYCLE ENERGY IMAPCT Defence against large scale concrete structures: Carbon emission from a concrete constructed building can be neutralized using building operation strategies
- 10. CONCRETE gives a great flexibility in a design. Using it we can build complex shapes and structures with great stability.
- 11. PRE-CAST CONCRETE CONSTRUCTION makes it feasible to construct in large quantity at a faster pace with a complete module ready as compared to MUD CONSTRUCTION which requires mostly on-site casting
- 12. VARIOUS GREEN OPTIONS AVAILABLE IN CONCRETE CONSTRUCTION AS COMPARED TO CONVENTIONAL CONCRETE
- 13. The Seismic performance of CONCRETE STRUCTURES is better as compared to MUD STRUCTURES. • It is very weak in shear, tension and compression. • Separation of walls at corner and junctions takes place easily under ground shaking • After the walls fail either due to bending or shearing in combination with the compressive loads, the whole house crashes down • Extensive damage was observed during earthquake especially if it occurs after a rainfall
