بررسی و مقایسه آزمون های ارزیابی پارامترهای دوام بتن درحاشیه خلیج فارس

Following the growing economic and industrial development, concrete is to find a special place as building materials, as optimization of materials and components of this structural material in order to increase its durability and long service life, significant economic and industrial benefits will follow. So Performance of Durability control tests , during and after the concrete construction, Approach to achieving durable concrete production in order to obtain sustainable development in the region is essential. In this paper, some of the concrete durability tests were performed on 216 samples of six concrete mixtures with different water-binder ratios, pozzolans (fly ash and silica fume). Based on the scattered results obtained from the experiments, depth of penetration of water under pressure test is not reliable in concrete quality evaluation. Also, lack of equipments and high expense of RCPT, despite its extensive use in many regions of the world, have led to limited use of this method in concrete projects in Iran. The capillary water absorption test for its quickness, convenience, low cost and good repeatability, seems to be able to serve as a measure of the concrete durability in marine areas, although it would require more research.
