Papercrete is a building material made from recycled paper, Portland cement, and sand. It is produced by mixing these ingredients into a slurry that can be poured and molded like concrete. Papercrete has benefits like being lightweight, a good insulator, and environmentally friendly since it uses recycled paper. However, it also has drawbacks like low structural strength, absorbency of water, and lack of approval by building codes. Overall, papercrete is a sustainable building material option for small, single-story structures.
Papercrete is a building material made from a mixture of shredded paper, water, and Portland cement. It can be poured into molds and sets into strong, lightweight blocks like concrete. Papercrete has insulating and sound absorbing properties that make it suitable for construction. While it is not structurally strong enough for load-bearing walls, papercrete can be used for inner walls and decoration. It is an environmentally friendly alternative to concrete that utilizes waste paper but lacks regulatory approval and its use at large scale could increase deforestation.
Papercrete is a construction material which consists of re-pulped paper fiber with Portland cement or clay and/or other soil added. First patented in 1928, it was revived during the 1980s.

RESEARCH ON THE EFFECTS OF HYPO SLUDGE AS A PARTIAL REPLACEMENT OF CEMENT MORTARIRJET Journal
This document summarizes research on using hypo sludge as a partial replacement for cement in mortar. Hypo sludge is a waste product from paper production that is currently disposed of in landfills. The study investigated replacing 0-50% of cement in mortar mixes with hypo sludge. Tests found that replacing up to 20% of cement with hypo sludge had little impact on the compressive strength and density of the mortar. Replacing more than 30% of cement led to significant reductions in strength. The study concluded that hypo sludge can effectively replace up to 20% of cement in mortar, providing an eco-friendly way to utilize this industrial waste.

Papercrete Bricks An Alternative Sustainable Building MaterialIJERA Editor
A large amount of non-renewable resources is consumed by the construction industry throughout the world. Everyday tons of waste papers are discarded as landfill or dump sites than those recycled. It is learnt that it takes about fifteen trees to make a ton of paper which means that 720 million trees are used once and then buried as landfills each year. In order to address these issues it has become imperative to push the boundaries of research in the field of innovative sustainable construction materials. This study is one such kind of efforts. Papercrete is a new composite material comprising of waste papers and cement. In this investigation, an attempt is made to produce an alternative material using waste papers. This could help eradicate a few of the environmental hazards caused by the construction industry. But there is no proper code for the mix proportioning of papercrete bricks. Therefore, a mix proportion of [Cement: Paper : Sand] 1:1.15:1.3 was chosen on trial and error basis. All the necessary engineering properties are studied and compared with the conventional bricks and discussions on its potential uses are made.

This document summarizes an experimental investigation on concrete with coarse aggregate replaced with waste concrete aggregate. Concrete mixtures were prepared by replacing the natural coarse aggregate with 10%, 20%, 30%, and 40% waste concrete aggregate. The compressive strength and flexural strength of the concrete mixtures were then tested at various curing ages. The results showed that concrete mixtures with up to 30% replacement of natural aggregate with waste concrete aggregate exhibited similar strength properties. However, strength was reduced with 40% replacement, with the 40% replacement concrete showing a 14.36% lower compressive strength and 27.45% lower flexural strength compared to the natural aggregate concrete. Therefore, the study concluded that up to 30% replacement can be considered optimal without comprom

This document presents a study on reinforcing concrete with coconut fibers and partially replacing cement with ground granulated blast furnace slag (GGBS). The study aims to utilize industrial wastes like coconut fibers and GGBS to reduce environmental pollution. Concrete cubes were made with 0-20% GGBS replacement of cement and 0-2.5% coconut fiber addition. Compressive strength testing at 7, 14, and 28 days showed strength increased up to 10% GGBS and 1.5% fiber, but decreased with further increases. The maximum strength was achieved with 10% GGBS and 1.5% fiber, indicating industrial wastes can improve concrete strength while reducing cement usage.
Experimental Study of Partial Replacement of Fine Aggregate with Waste Materi...IJRES Journal
The utilization of industrial and agricultural waste produced by industrial process has been the focus of waste reduction research for economical, environmental and technical reasons. This is because over 300 million tones of industrial waste are being produced per annual by agricultural and industrial process in India. The problem arising from continuous technological and industrial development is the disposal of waste material. If some of the waste materials are found suitable in concrete making not only cost of construction can be cut down, but also safe disposal of waste material can be achieved. The cement of high strength concrete is generally high which often leads to higher shrinkage and greater evaluation of neat of hydration besides increase in cost. A partial substitution of cement by an industrial waste is not only economical but also improves the properties of fresh and hardened concrete and enhance the durability characteristics besides the safe disposal of waste material thereby protecting the environment form pollution This paper deals with partial replacement of fine aggregate with the industrial waste from China Clay industries. The compressive strength, split tensile strength and flexural strength of conventional concrete and fine aggregate replaced concrete are compared and the results are tabulated.

Use of Fly ash and Plastic in Paver BlockIRJET Journal
This document discusses an experimental study on using fly ash and plastic in concrete paver blocks. The study aims to evaluate the performance of plastic-concrete mixes for paver blocks. Several concrete mixes were tested with varying percentages of fly ash substituted for cement, and plastic pieces added. The compressive strength of resulting paver blocks was tested after 3 and 7 days of curing. Results showed that replacing cement with up to 20% fly ash, or adding plastic pieces, increased the compressive strength of the blocks over time. Using waste materials like fly ash and plastic in paver blocks can improve properties while reducing costs and waste disposal impacts.
Strength of Corrugated Roofing Elements Reinforced with CoirIRJET Journal
1) The study evaluated the strength properties of corrugated roofing sheets reinforced with coconut (coir) fibers and fly ash.
2) Samples of corrugated roofing sheets were produced by casting mixtures of cement, sand, water, coir fibers (0.1-0.4% by volume) and fly ash (10-30% cement replacement).
3) The samples were then tested to determine their flexural strength, impact resistance, and water absorption. Test results showed that samples with 0.2% coir fiber and 20% fly ash replacement exhibited the highest flexural and impact strengths.
IRJET- Study on Concrete Replaced with Crushed Concrete Fine AggregateIRJET Journal
This document studies the use of crushed concrete as a replacement for natural fine aggregate in concrete. Four mixes of M20 grade concrete were tested with fine aggregate replaced at 0% (control), 25%, 50%, and 100% with crushed concrete aggregate. Specimens were tested for compressive strength, split tensile strength, and flexural strength at ages of 1, 7, and 28 days. Test results found that early compressive strength was lower for mixes with replacement aggregate but 7-day and 28-day strengths increased compared to the control in some mixes. Mixes with 50% and 100% replacement showed increases in split tensile strength at 7 days. Flexural strength increased at 1 and 7 days for mixes with replacement aggregate
IRJET - An Experimantal Study on Behaviour of Hollow Fly Ash Concrete Blocks ...IRJET Journal
This document summarizes an experimental study on the behavior of hollow fly ash concrete blocks as a replacement for conventional bricks. Various mix designs were tested to improve the mechanical properties of the blocks. The compressive strength, water absorption, modulus of rupture, and dry density of newly manufactured hollow fly ash concrete blocks were compared to traditionally made blocks. Results showed that the proposed mix ratios significantly increased the compressive strength and decreased the water absorption of the hollow fly ash concrete blocks compared to the original mixes. Sixteen blocks were tested based on four mix designs with varying fly ash content. The mix with 20% fly ash content performed best in terms of compressive strength and other properties.
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.

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%.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
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
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
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.
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
