The boron active belite (BAB) cement is a cement type different from Portland cement due to the presence of B 2 O 3 at 3-4%, low hydration temperature, low early strength and high final strength. In this study, concretes with three similar gradations were produced using BAB, CEM I 42.5 and CEM II 32.5 cements. Prepared cylindrical (Ø100/200 mm) concrete samples were exposed to high temperatures of 200, 400 and 600°C at the end of 7 th , 28 th and 90 th days of standard water curing periods. Then, the compressive strength, ultrasonic pulse velocity and Schmidt hammer strength properties of the concretes were investigated to determine their resistance to high temperatures. As a result, the compressive strength values of concrete with BAB cement were found to be higher in the final period than in concrete with normal Portland cement. Therefore, it can be said that the concretes produced with BAB cement is more durable against elevated temperatures from concretes produced with normal Portland cement. Moreover, the observed strength differences in concretes with BAB cement, were discussed in the light of current information in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
