Experimental Study on Compressive Strength of Brick Using Natural Fibres
Despite the use of modern materials, clay bricks are reasonably preferable materials nowadays. However, the moo fetched and flexibility of clay bricks are not related with tall natural and feasible values, particularly with regard to crude fabric sources and fabricating processes. Agricultural world is growing fast, with increased rural arrive development and land cultivation leading to massive...
متن کاملAssessing the Strength of Carbon Fibres
Data on the strength of carbon fibres, first examined by Crowder (1994), are re-analysed. The new analysis is Bayesian and is implemented using Markov chain Monte Carlo methods. The flexibility of this approach allows an extended form of Crowder’s model to be considered, and provides more reliable measures of precision for parameter estimates. The results obtained lead to an improved understand...
متن کاملGlass fibres: absence of pulmonary hazard in production workers.
Glass fibres: absence of pulmonary hazard in production workers. Seventy fibreglass workers with a mean of 19-85 years in the industry are compared with a control group having no exposure to glass fibre but otherwise matched for age, sex, height, and weight, and residing in the same geographical area. Comparison was made by radiography, the administration of the modified Medical Research Counci...
متن کاملSensing properties of germanate and tellurite glass optical fibres
Strain and thermal sensitivities of germanate and tellurite glass fibres were measured using a fibre Fabry-Perot (FFP) interferometer and fibre Bragg gratings (FBG). The strain phase sensitivity for germanate and tellurite fibre were 5900×10 rad/m and 5600×10 rad/m respectively at a central wavelength of 1540nm using FFP interferometer, which is consistent with the value of 1.22pm/με obtained f...
متن کاملStatistical Analysis of Structural Glass Strength
In contrast to most other building materials the strength of glass is not a material parameter, but rather a combination of the material treatment and the load position effects. Structural glass elements are produced with heat treatment when compressive residual stresses are created on the surface. The loading position of glass specimen is also significant due to variations in material quality....
