Sulphate corrosion occurs due to a chemical reaction between the hydration of cement, which is a concrete compound, and sulphate ions, resulting in deterioration in concrete. Pozzuolanas such as fly ash are used instead of cement to reduce or minimize damage caused by sulphate on concrete. This study uses fly ash tailings from Afsin Elbistan thermal power plant, which has a component close to cement instead of cement, which is one of the main components of concrete. Examples of different fineness obtained by grinding the fly ash (FA) in the ball mill for 0, 10 and 20 minutes were prepared with a FA substitution rate of 10%, creating examples of fly ash-added concrete. These examples were then exposed to a 10% and 5% additive sulphate solution and tested for compressive strength and ultrasonic pulse velocity measurement tests to investigate the effect of concrete samples on sulphate resistance. According to the results obtained, the compressive strength values of concrete samples exposed to a solution of 5% and 10% sulphate have been observed, depending on the fly ash grinding time. It has been found that the concrete samples added have reduced compressive strength by increasing the amount of sulphate solution and have a higher compressive strength value than the reference sample. However, weight losses have been reduced as the grinding time increases. It has also been determined that ultrasonic pulse velocity values have increased as a result of the increase in the fineness of the grinding and the fineness of the flying ash.

Our country is very rich in terms of boron mine. It has been observed that there are few studies on the use of borax pentahydrate in concrete. In this study, the properties of cement mortars produced by substituting borax pentahydrate in cement at 5, 10, 15, 20 and 25% by weight were investigated. For this purpose, some mechanical and physical experiments were carried out to examine the sound transmission velocity, flexural and compressive strength properties of cement mortars. As a result of the tests and experiments, it was observed that the use of borax pentahydrate decreased the flexural and compressive strength values in cement mortars. It was determined that the highest flexural strength, compressive strength and ultrasonic sound velocity transmission among borax pentahydrate substituted cement mortars were obtained from 5% borax pentahydrate substituted mortars.

“…When the use of BFS as aggregate in the literature and the sulphate strengths of using BFS and pumice instead of a certain amount of aggregate in concrete pipe production; It was observed that the weight loss was the lowest in BFS and pumice added samples. While samples kept in sulphate solution for 180 days showed the best resistance of samples with 15% BFS, while the most unstable sample was the witness sample [11]. Nataraja et al [12] investigated the use of fine aggregate GBFS in cement mortar.…”

Cement, water and fine aggregate mixture is called mortar. Mortar samples suitable for the desired purpose can be obtained by adding various additives to the mortar samples. In this study, instead of standard sand, blast furnace slag (BFS) was used at 10%, 20% and 30% by weight in mortar samples. In order to determine the mechanical properties of the samples, compressive and flexural strength tests were applied. For the electrical resistivity values, a device with constant 30V voltage was prepared and the electrical resistivity values were measured. To determine the freeze-thaw resisting properties, it was applied sodium sulfate experiment. As a result, it was seen that the best values were obtained from 30% BFS additive samples in all series. The highest resistivity values are in the sample with 30% BFS doped with 0.1856 ohm.m and 0.268 ohm.m values. The highest freeze-thaw resisting value was seen in the sample with 30% BFS with 1.35%.
