علل فرسودگی و تخریب سازه های بتنی

علل مختلفی كه باعث فرسودگی و تخریب سازه های بتنی CAUSES OF DETERIORATIONS می شود همراه با علایم هشدار دهنده دیگری كه كار تعمیرات را الزامی می دارند، در نخستین بخش از این مقاله مورد بررسی و تحلیل قرار می گیرند.

 1-1- نفوذ نمكها  (INGRESS OF SALTS)
نمكهای ته نشین شده كه حاصل تبخیر و یا جریان آبهای دارای املاح می باشند و همچنین نمكهایی كه توسط باد در خلل و فرج و تركها جمع می شوند، هنگام كریستالیزه شدن می توانند فشار مخربی به سازه ها وارد كنند كه این عمل علاوه بر تسریع و تشدید زنگ زدگی و خوردگی آرماتورها به واسطه وجود نمكهاست.  تر و خشك شدن متناوب نیز می تواند تمركز نمكها را شدت بخشد زیرا آب دارای املاح، پس از تبخیر، املاح خود را به جا می گذارد.

Never has there been replica handbags so synonymous with style as Hermès's iconic Kelly Bag. Named after actress and real life princess Grace Kelly, this bag is made with some kind of magic. Not only has it managed to stay just a chic as it was in the 1930s when the style made its debut, the Kelly also has major covetable cache—even if it’s not your style, you can't deny you’d join the line to get your hands on one. And thanks to its latest reboot, that line is about to get longer. Part of the French brand's genius is that the Kelly family of arm candy knows how to walk the line between classic and contemporary. Each new version of the louis vuitton replica maintains the same iconic shape but with fresh color palettes, prints, artist collaborations, and sportier takes to keep up with the times—which means keeping up with the age of the smartphone. This week Hermès debuted the Kelly Mini II, a bag just big enough for your phone and cute enough to have you mentally justifying the investment. The latest version is slightly larger than the brand’s last tiny bag, the Kelly Micro—a retooling done specifically to accommodate the largest smartphones on the market. The Kelly Mini II makes carrying your phone and your go-to gloss (it won’t fit a whole lot more) supereasy, with a shoulder strap that's pretty much made for street-style shots. Though small, the Mini II is made to stand out in a range of vibrant hues, including electric blue, rich saffron, perky peach, and a fresh crimson. Just like the bigger versions, getting your hands on one of the iconic miu miu replica bags won’t come cheap. The Kelly Mini II starts at $7,700. Despite the eye-bulging price point, the bag has major cool-girl potential. Plus it's on trend with the latest string of mini bags we’ve seen gracing the hips of street-style stars such as Chiara Ferragni. Start lining up.

In both men and women, I think Hermes handbags and the Rolex Watches are used more interchangeably than watches for men and women.It is particularly common to see women wearing men's Luxury Breitling Watches. Me, for example, I wear Original Omega Watches Must 21 of my boyfriend with the black rubber strap.There are many legitimate 1:1 IWC online retailers that sell new certified watches.?At their lower prices, Cartier watches become watches at discounted prices and that's a good thing! Rolex Submariner Watche have splendid styles and designs giving the product a unique style.
