Abstract
Throughout the world, the most widely used construction material is concrete. It is the second most consumed substance on the earth after water. As concrete being used for construction of most of the buildings, bridges etc., it has been labelled as the backbone to the infrastructure development of nation. It is commonly made by mixing Portland cement with sand, crushed rock and water. It is very clear that among the all components, aggregate and water is largely available material in India at very low cost. As cement is comparatively high cost it would be advisable to use other locally available industrial and agricultural waste material to replace the cement partially. Ground Granulated Blast-furnace Slag (GGBS) is a non-metallic and non-hazardous waste material of Iron Industry. Therefore the minimization of this waste material without a harmful effect on nature has a vital importance.The present work focused on the utilization of GGBS in concrete which can be suitably used under the Indian conditions. For this purpose, the various tests on properties of green and hardened concrete have been performed. The properties of green concrete have been analyzed by workability of concrete in terms of slump value whereas the properties of hardened concrete have been analyzed in terms of mechanical and physical properties of concrete. The mechanical properties of hardened concrete include the compressive strength, flexural strength and split tensile strength whereas physical properties includes the dry & moist density and water absorption of hardened concrete. On the basis of present work we found that GGBS in concrete improves workability, compressive strength, flexural strength, split tensile strength and decreases the density & water absorption characteristics of hardened concrete. As a result the cost of concrete decreases. Also GGBS leads to the significant reduction in the quantity of cement which enables the reduction in CO2 emission and reduction in energy consumption in production of cement.

IRJET- Design of 300 Years Durable Concrete for Nuclear Confinement Zone ...IRJET Journal
This document discusses the design of a 300-year durable self-compacting concrete for use in nuclear confinement zones and tunnel formworks. The concrete mixture uses materials like cement, silica fume, Alccofine 1203, coarse aggregate, fine aggregate, and an admixture to achieve high durability and self-compaction properties. Silica fume and Alccofine help reduce carbonation and permeability through pozzolanic reactions and fine particle sizes. A water-binder ratio of 0.28 provides sufficient workability while ensuring complete hydration. This concrete is predicted to last 300 years based on durability modeling software.

Abstract
Throughout the world, the most widely used construction material is concrete. It is the second most consumed substance on the earth after water. As concrete being used for construction of most of the buildings, bridges etc., it has been labelled as the backbone to the infrastructure development of nation. It is commonly made by mixing Portland cement with sand, crushed rock and water. It is very clear that among the all components, aggregate and water is largely available material in India at very low cost. As cement is comparatively high cost it would be advisable to use other locally available industrial and agricultural waste material to replace the cement partially. Ground Granulated Blast-furnace Slag (GGBS) is a non-metallic and non-hazardous waste material of Iron Industry. Therefore the minimization of this waste material without a harmful effect on nature has a vital importance.The present work focused on the utilization of GGBS in concrete which can be suitably used under the Indian conditions. For this purpose, the various tests on properties of green and hardened concrete have been performed. The properties of green concrete have been analyzed by workability of concrete in terms of slump value whereas the properties of hardened concrete have been analyzed in terms of mechanical and physical properties of concrete. The mechanical properties of hardened concrete include the compressive strength, flexural strength and split tensile strength whereas physical properties includes the dry & moist density and water absorption of hardened concrete. On the basis of present work we found that GGBS in concrete improves workability, compressive strength, flexural strength, split tensile strength and decreases the density & water absorption characteristics of hardened concrete. As a result the cost of concrete decreases. Also GGBS leads to the significant reduction in the quantity of cement which enables the reduction in CO2 emission and reduction in energy consumption in production of cement.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
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%.
