Research ArticleOpen accessEvery word in the titleImproving the Quality of Ceramic and Cemented Carbide Cutting Inserts by Diamond GrindingTareq Ahmad Abu Shreehah, Rasheed Abdulateef AbdullahThe machining of hardened steel and other difficult-to-cut materials require high quality and progressive cutting tools to meet the growing requirements for increasing productivity, improving tool life and quality of the cutting process. This study deals with an experimental investigation on the quality improvement by diamond grinding of ceramic and cemented carbide cutting inserts, comparing it with conventional batch produced … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,194 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImprove the Consumption of Cement and Sand in Massive ConcreteKaveh Ostad-Ali-Askari et al.The massive concretemixing plan is very important due to its large volume of use in concrete dams.Productivity can be increased in dam manufacturing industry by adopting asuitable method for mixing mass concrete that can meet design, executive andeconomic needs. Because of intensification rate construction of dams newperiods and high cost of implementing such projects any step that reduces theircost of … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 1 Nov 2021 · 6,347 accessesView PDFCite
Case ReportOpen accessIn the keywordsAltered Passive Eruption: A Combined Perio-Restorative Approach: A Case ReportFarah Antar, Racha Hajj, Maroun Dagher, Elie ZebouniAltered passive eruption is described as a condition in which the relationship between teeth, alveolar bone and the soft tissues creates an excessive gingival display and, in turn, in some circumstances, it may reveal a clinical aspect known as the gummy smile. A 29-year-old male patient presented to a dental clinic in Beirut, Lebanon, complaining about short looking teeth and … …Current Research in Dentistry, Vol. 12, Issue 1 · 27 May 2021 · 7,047 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAerosol Filtration Using Quartz Sand FilterAbbas H. Sulaymon, Yasmen A. MustafaThe cement industry is the major source of cement dust which contains heavy metals like nickel, cobalt, lead, chromium, arsenic and hazardous substances like dioxins and furans. Exposure to these substances can cause health problems to human, animals and vegetation. A continuous pilot scale quartz sand filter was constructed and uses to study the effect of important design parameters (temperature, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 20 Jun 2012 · 7,716 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,956 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluences of Short Discrete Fibers in High Strength Concrete with Very Coarse SandMahyuddin Ramli, Kwan Wai HoeProblem statement: High Strength Concrete (HSC) normally content high cementitous amount and low water binder ratio. However, these would cause substantial volume changes to the concrete and therefore affected the strength development. In addition, the brittleness of HSC was increased when silica fume used as partial cement replacement to achieve high strength. Approach: This study discussed the effects of incorporated … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,812 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRational Mix Design Approach for High Strength Concrete Using Sand with very High Fineness ModulusKwan Wai Hoe, Mahyuddin RamliProblem statement: Production of concrete is always deal with inconsistency. Sources of variation like materials from different geographical basis, mix design method, fineness of aggregates and so on will attribute to different level of achievement of the concrete. Even though researcher had verified that higher fineness modulus of sand would yield better performance for the concrete, but so far there … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 8,217 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Polypropylene Fibers on the California Bearing Ratio of Air Cured Stabilized Tropical Peat SoilBehzad Kalantari, Bujang B.K. Huat, Arun PrasadProblem statement: Peat soil is well known to deform and fail under a light surcharge load and is characterized with low shear strength, high compressibility and high water content. With the rising demand from the construction industry, utilization of these soils is required and suitable technique needs to be found out for stabilizing them. Approach: Model study had been carried … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,697 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSustainable Development through Waste Heat RecoveryP. S. Bundela, Vivek ChawlaProblem statement: Waste Heat Recovery (WHR) steam Technology is a proven Technology pioneered by Japanese for cement plant and it is economically viable. Electrical Power can be generated by adopting the latest technology in this field. It used a medium to low temperature (120-350°C) Turbine technology (standard thermal power plants run on steam temp-500°C). Approach: It requires treat exchangers (Hx) … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPile Instrumentation Using Retrievable SensorsFaisal Hj. Ali, Bujang B.K. Huat, Lee Sieng KaiStrain gauges are normally used to monitor the shortening or compression of pile during static pile load test. For concrete spun pile, the technique used either by incorporating high temperature-resistant strain gauges into the heat-cured production process of the spun piles or by installing an instrumented steel pipe into the hollow core of the spun piles followed by cement grout … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,612 accessesView PDFCite
