While permeability is believed to be the most important criterion, it can be impacted by the stress-strain properties of the wall, which define the strength and stiffness. This study investigates the influence of curing time, confinement, rate of axial deformation, and quantity of cement (mix of Portland cement (PC) and ground granulated blast furnace slag (GGBS)) on the stress-strain properties of CB slurry walls. An unconfined compressive test supported by (i.e. UCT) undrained triaxial (UUT) tests were carried out on specimens prepared from two mix-designs (differentiated by the proportion of GGBS in the cement component) and cured 7, 14, 28, 60 and 90 days. Two rates of deformation (1.0mm/min and 1.2mm/min) were examined, using a range of confining pressure (i.e., 50 200 kPa) in the UUT. The results reveal that varying rate of deformation and the range of confining pressures have no clear influence on the mechanical properties (e.g., deviator stress, shear strength and stiffness) of the CB mix-designs. However, increased curing time, and the proportion of GGBS significantly improved these properties. An increased proportion of GGBS enhances early strength. Thus, further work needs to be done to establish a balance between adequate strength and adequate flexibility of CB walls in order to not compromise permeability.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85819518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In network reconfiguration, a key role is to find the appropriate network topology that does have the lowest losses during any conditions present within the network. Reliability, security, and system operating limitations are the most significant parts of the network reconfiguration that are suitable. In the work, the authors suggested to apply Tabu search optimisation technique to solve the problem of network reorganisation in the distribution system by creating a stochastic model of a virtual zone based on data prepared in a previous study by the first author. The stochastic model consists of four feeders and 106 buses. The validity of the suggested technique is verified by relying on standard practices and its ability to establish a correct network topology in the system distribution. This investigation determines that the suggested technique is excellently suitable for creating a virtual zone network and can be applied in reality.

In this research work, green composites have been developed with jute fibers as reinforcement and poly lactic acid as matrix material using compression moulding technique. All composites were developed with maintaining the reinforcement as 30% fiber volume fraction. The influence of curing temperature with the range of 160°C, 170°C and 180°C was investigated for various mechanical properties of developed composites and degradation behaviour of developed composites were analysed using soil burial test. Results acquired from the tests specify that the tensile and flexural strength decreases with upsurge in curing temperature. Morphology study using scanning electron microscopy is further justified the findings obtained from mechanical tests. Biodegradation study was done on the all the three different composites under the soil burial conditions for 9 months and results indicate that composites developed at 160°C degrade faster as compared to others.

To make it easier for tourists to visit and get tourist destination information, several researchers developed a mobile application-based information system.

The purpose of this research is to develop and analyze applications regarding the potential of Gunungkidul culture based on progressive web apps and which can be used without having to install applications and can run in all operating systems. The application development method uses Scrum and Ionic Framework as a framework for the application. The performance analysis method was tested on runtime performance (loading, scripting, rendering, painting, system) and memory usage (min JS Heap and max JS Heap) by using Chrome Developer Tools for 30 tests.

The biomass used is fiber, shells, and empty fruit bunches. Energy efficiency is needed in the process; therefore, it requires energy balance in the power generation system, distribution, and use of energy produced by biomass. PKS Rimbo Duo has a processing capacity of 30 tonnes/hour. Broadly speaking, the energy system at PKS Rimbo Dua includes steam energy production equipment such as boilers and steam and electricity energy conversion equipment in the form of steam turbines and generators (alternators) as well as storage equipment for the expansion of steam energy in the form of opposing pressure storage vessels (BPV). Energy balance analysis is carried out by analyzing data methods obtained from the performance of operating equipment and conducting field surveys and measurements of predetermined parameters, especially in boilers, water treatment, and turbines. Analysis of fuel use is also carried out to determine the quality of the fuel and the potential for steam produced. The result of this research is that the average efficiency of the boiler is 63.23%, which is still below the 73% boiler design. One of the reasons is that the flue gas temperature reaches 260 oC. The steam turbine has an efficiency of 44% isentropically with SSC = 31.9 kg / kWh when compared to the standard norm, the SSC value is still too high. The results of the water analysis also found the P and M alkalinity values, and the water pH was still 9.8. The results of the analysis of these data can be used as a reference for actions whether it is a repair of equipment, replacement of equipment, and improvement of operational parameters.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78643392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
