This document reviews the use of manufactured sand as a replacement for natural sand in concrete. It discusses the fresh, hardened, and durability properties of concrete made with manufactured sand with and without mineral admixtures. Several studies have found that manufactured sand concrete can achieve comparable or improved strength and durability compared to natural sand concrete. The workability of concrete decreases with higher replacements of manufactured sand due to its angular shape and texture, but workability can be improved with the use of admixtures. Mineral admixtures like fly ash, GGBS, and bagasse ash can further improve the properties when used with manufactured sand concrete.

This document presents an experimental study on the effect of replacing natural sand with artificial sand in concrete properties. Natural sand is being depleted due to excessive construction and environmental issues. The study explores using artificial sands like wash sand, foundry sand, and crushed sand as replacements for natural sand in concrete mix designs.

This document summarizes an experimental study on using unseived stone dust as a replacement for river sand in cement mortar. Sieve analysis and physical tests were conducted on the stone dust and river sand. Mortar mixes with ratios of 1:3 to 1:6 were made with both stone dust and river sand to determine water requirement and compressive strength. The results showed that stone dust mortar requires slightly more water but achieves equal or higher strength compared to river sand mortar, especially for ratios of 1:4 to 1:6. The study concludes that unseived stone dust can be effectively used as a replacement for river sand in making mortar.
Experimental investigation was carried out to study the feasibility of unseived stone dust (a
product obtained from crushing of granite) as fine aggregate in place of river sand in making cement
mortar 1:3, 1:4, 1:5 and 1:6, which are the mixes usually adopted in various construction activities.
The results obtained are comparable with the conventional mortar. It is concluded that the
compressive strength at 28 days of unseived stone dust used as fine aggregate in mortar gives 5%
higher strength for the ratio of 1:4, 1:5, and 1:6, where as 5% less than the conventional mortar for
the ratio 1:3. Therefore the unseived stone dust in raw form can be confidently used as a good

The study involves casting concrete cubes with different percentages of hypo sludge replacing cement (0%, 5%, 10%, 15%, 20%, 25%, 30%), while using manufactured sand instead of river sand. The cubes will be tested for compressive strength. Previous research shows that manufactured sand can be a viable alternative to river sand. Using waste materials like hypo sludge in concrete can improve sustainability while reducing construction costs and environmental impacts. The goal of this study
IRJET- Tyre Rubber Powder as a Soil StabilizerIRJET Journal
This document summarizes a study on the use of tire rubber powder as a soil stabilizer. The study investigated how adding different percentages of crumb rubber powder (0%, 5%, 10%, 15%) impacted the shear strength and bearing capacity of black cotton soil.

The results showed that replacing up to 40% of sand with quarry dust increased the density and compressive strength of the concrete while still maintaining adequate workability. Replacing sand with quarry dust up to 40% produced equivalent or better results compared to

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
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.

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.
