[ 1 ] - ارزیابی مقاومت بتن خودتراکم پلیمری درتیرهای بتن آرمه
در این مطالعه ارزیابی مقاومت بتن خود تراکم حاوی ذرات خرد شده ضایعات لولههای PVC در تیرهای بتن آرمه با ابعاد 35/0×5/0×1/2 متر با استفاده از روشهای مغزهگیری و اولتراسونیک مورد توجه میباشد. دو نسبت آب به مواد پودری 39/0 و 47/0 استفاده شده که میکروسیلیس و پودر سنگ آهک به عنوان پرکننده به کار رفته است. همچنین در صدهای مختلف ذرات خرد شده ضایعات لولههای PVC به میزان 5% و 10% با رعایت محدودیتهای ...
[ 2 ] - Seismic Behavior Evaluation of Concrete Elevated Water Tanks
Elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. These structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. Damage to these structures during strong ground motions may lead to fire or other ...
[ 3 ] - Evaluating the Application of Reinforcement Correction Factor for Concrete Core Testing
This study investigates the reinforcement correction factor of concrete core in more detail to prepare appropriate outlines for interpretation of results. This investigation aims to minimize uncertainties involved to carry out the more realistic condition assessment of suspect buildings before taking up retrofitting/strengthening measures. For this purpose, an extensive experimental program inc...
[ 4 ] - In situ strength assessment of concrete using recycled aggregates by means of small diameter cores.
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...
