Moisture content of RC structures regards the cement hydration level and short-term strength development of concrete, as well as the phase-distribution (solid, gaseous, liquid) inside concrete and its long-term durability. The presence of chloride ions in RC structures in addition to moisture leads to steel rebar corrosion. This thesis describes a new microwave nondestructive evaluation technique using non-contact\/non-intrusive synthetic aperture radar (SAR) imaging to quantify the w\/c ratio, subsurface moisture content, and chloride content of concrete panel specimens. Concrete panel specimens made of three w\/c ratios (Z = 0.4, 0.5, 0.55) and six chloride contents (S = 0, 2, 4, 6, 8,and 10% by cement wt.) at a w\/c = 0.45 were air-dried for approximately f months and scanned by a laboratory 10-GHz SAR imaging system. Quantitative analysis of SAR images was carried out by the K-R-I transform to understand the simultaneous change of SAR amplitude and shape at different moisture levels.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202814850\"\u003e\u003ch3\u003eTheory and Experiment\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786202814850","offer_id":39449554550877,"sku":"9786202814850","price":71.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f8488844-57de-4a5c-917e-2da0691e6f4a.jpg?v=1772868548","url":"https:\/\/shop.autorenwelt.de\/products\/quantifying-moisture-and-chloride-contents-inconcrete-using-synthetic-theory-and-experiment-von-ahmed-alzeyadi","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
