Performance evaluation of sugar cane bagasse ash on the strength of concrete: A sustainable approach
Cement is the most sought material in world next to water. The manufacturing and utilization of cement increasing rapidly leading global warming due release CO2. In this research, it intended partially substitute with agro-based byproducts i.e. bagasse ash (SCBA) as supplementary cementitious materials (SCM). Meanwhile, effect SCBA (added at various proportions 5–30 %) on compressive tensile st...
In this study the Sugar cane bagasse ash (SCBA) was characterized for chemical composition, morphological and mineralogical properties. From XRF analysis it found that SCBA has SiO2, Al2O3, Fe2O3 CaO content of 67.25%, 6.37%, 4.21% 13% respectively a very low LOI value 0.34% can be classified as Class F ASTM pozzolan according to C 618-2009. used pozzolanic material after grinding less than 45 ...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Using biomass waste as supplementary cementing material (SCM) in concrete has attracted researchers’ attention for efficient utilization and reducing cement demand. Sugarcane bagasse ash (SCBA) is one such example of waste. It an agricultural obtained when sugarcane from the sugar industry used power generation disposed open-air dumping sites. Its disposal causes particulate matter, degrading a...
in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...
The purpose of this study was to investigate left-ventricular function during strenuous exercise with the self-contained breathing apparatus (SCBA). With the use of two-dimensional echocardiography, images of the left ventricle (LV) were acquired during sustained exercise (3 x 10 min) under two conditions: 1) SCBA, or 2) low resistance breathing valve. Twenty healthy men volunteered for the stu...
the present paper deals with criminal issues. for example, legal injunction on the necessity of returning a deposit has a legal nature and legal injunction on the punishment of those who breach the trust has a criminal nature. existing social issues are the basis of classification of some instances into the issue, some of which are based on variation and others on quality. therefore, the motiva...
the purpose of this two-phase, sequential mixed methods study was to find out whether there were any decencies between male and female ma students’ theses regarding the common features of academic writing such as syntactic complexity, means of integrating cited information, and organizing arguments. i chose 10 male written theses and 15 female written theses in tefl and linguistics. in the firs...
In the present investigation effect of urban environment city Xalapa, Ver., México in depth carbonation Sustainable Concrete made with Agro-Industrial and Industrial Waste Materials like Sugar Cane Bagasse Ash (SCBA) Silica Fume (SF), was evaluated. The Concretes Conventional (Concrete reference) were designed for a relation water/cement= 0.65 according to indicated ACI 211.1. elaborated 100% P...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
