This document summarizes a research study that investigated the effect of partially replacing cement with groundnut shell ash (GSA) and replacing sand with washed bottom ash (WBA) on the characteristic properties of concrete. GSA and WBA are waste materials that are available in large quantities and can potentially be used to replace cement and sand in concrete production.

The resulting concrete was tested to determine properties like workability, compressive strength, split tensile strength, and flexural strength after different curing periods. The results showed that concrete workability was acceptable with GSA and WBA replacements. However

Use of Granite Waste as Partial Substitute to Cement in ConcreteIJERA Editor
With the ever increasing cost of construction materials there is a need to curtail the same by using cheaper substitutes. In this investigation Granite Slurry (GS) was used as partial substitute in proportions varying from 5% to 20% by weight to cement in concrete and tested for compressive strength, tensile strength and flexure strength. It was observed that substitution of 10% of cement by weight with GS in concrete resulted in an increase in compressive strength to 48 N/mm2 compared to 35 N/mm2 of conventional concrete. Tensile strength too followed a similar pattern with a 10% substitution with GS increasing the tensile strength to 3.6N/mm2 compared with a 2.4 N/mm2 of conventional concrete. However flexure strength of 10% GS replacement exhibited a good improvement of flexural strength to 4.6 N/mm2compared to a 3.2 N/mm2 of conventional concrete. Further investigations revealed that to attain the same strength of conventional concrete a 20% substitution with GS is effective. So it can be concluded that when locally available GS is a good partial substitute to concrete and improves compressive, tensile and flexure characteristics of concrete, while simultaneously offsetting the overall cost of concrete substantially.

Cement clinker production is a high energy, resource intensive process that contributes significantly to annual global detrimental greenhouse gas emissions. Reduced clinker content in the manufacture of concrete by partial substitution of cement with supplemental cementitious materials is one possible technique to alleviate environmental difficulties or problems associated with cement based materials. Quarrying typically generates a large amount of waste. In general, processed quarrying production accounts for 30 of total stone removed, whereas waste quarrying trash and processing waste accounts for 70 of total stone extracted during this procedure. This wastage not only causes financial losses but also produces environmental issues, so in this experimental inquiry programme, we partially substitute the cement with marble dust in varied percentages, i.e. 0 , 5 , 10 , and 15 . In this project, we make concrete samples with varied mixes containing different percentages of marble dust. We execute several tests on these prepared samples, such as compressive strength testing, split tensile strength testing, and flexural strength testing. When we compared the test results of the prepared samples to conventional concrete, we discovered that with a partial replacement level of cement of up to 10 by marble dust, all physical properties such as compressive strength, split tensile strength, and flexural strength increased.

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

When we compared the test results of the prepared samples to conventional concrete, we discovered that with a partial replacement level of cement of up to 10 by marble dust, all physical properties such as compressive strength, split tensile strength, and flexural strength increased.

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

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
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.

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.

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
