By increasing the demolition of old concrete structures and the interest of civil industries to consume cheaper materials, using Recycled Concrete Aggregate (RCA) can cause environmental protection and decrease the construction costs. On the other hand, the high potential of Recycled Aggregate Concrete (RAC) in concrete industry was established by extensive experimental researches were performe...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

in-situ testing techniques have proven to be successful in improving the speed and reliability of geotechnical investigations. one of the most common in-situ methods in engineering geology and site investigation is cone penetration test (cpt), which is mainly used for characterization of soils, as it is a robust, simple, fast, reliable and economic test that can provide continuous soundings of ...

the objective of the present work was to formulate and evaluate mucoadhesive in situ nasal gels of loratadine. this drug delivery system may overcome the first-pass metabolism and subsequently improve the bioavailability of the drug. a total of 16 formulations of in situ nasal gels were prepared using different polymeric ratios of hydroxypropyl methylcellulose (hpmc k-100) and xanthan gum. all ...

polyvinyl ester green composites were synthesized with walnut shell powder (wsp) by in-situ polymerization technique. the green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...
