Durability of the polymer-modified mortars using the redispersible SBR and PAE powder-modified mortars were experimentally investigated. Results of a previous study were used to determine the mix proportion that optimized the strength, and the freezing-thawing resistence, the carbonation depth and the chloride intrusion depth of the mortar for various polymer-cement ratios were studied. After 300 freezing-thawing cycles, the rate of weight reduction decreased from 7 to below 2 $\%$ as the polymer-cement ratios increased from 0 to 15 $\%$, and, on the 150 cycle basis, durability index increased from 60 to 98. Carbonation depth decreased from initial value of 5.5 to about 2.5 mm and chloride intrusion depth did from 3.5 to 1.5 mm

Although concrete is a material widely used in the construction industry, it is very vulnerable to cracking and has a disadvantage in that durability deteriorates when cracks occur. When cracks occur, harmful factors are introduced through the micro-cracks of the structure, reducing durability. Therefore, in this study, as part of a study to alleviate the problems of maintenance and durability deterioration due to cracks in concrete structures, the mechanical properties of self-healing mortar according to the size of the capsule made of cement material were reviewed.

This paper provides a new approach for predicting the corrosion resistivity of reinforced concrete structures exposed to chloride attack. In this method, the prediction can be updated successively by a Bayesian theory when additional data are available. The stochastic properties of model parameters are explicitly taken into account into the model. To simplify the procedure of the model, the probability of the durability limit is determined from the samples obtained from the Latin hypercube sampling technique. The new method may be very useful in designing important concrete structures and help to predict the remaining service life of existing concrete structures which have been monitored.
