Özet:

Mineral additives are preferred to improve the physical, mechanical and durability properties of cement-based composites and to reduce the amount of cement used. By reducing the use of cement, it is ensured that environmental pollution and the high cost of cement production are prevented. In this context, Glass Powder (CT) and Fly Ash (UK) were added to the mixture by replacing 10%, 20% and 30% by weight of cement. In the production of the mortar samples, CEM I 42.5/R type Portland cement was used as the binder, and 0-4 mm crushed sand was used as the aggregate. After the samples produced in the laboratory with dimensions of 40x40x160 mm were removed from the mold, they were cured in the standard curing pool at 20±2 °C for 7, 28, 56, 90 and 180 days. Flow table test, compressive strength, flexural strength and electrical resistivity tests were performed on hardened mortar samples. According to the data obtained as a result of experimental studies, the addition of CT and UK at an early age decreased the electrical resistivity, but the resistance increased significantly as the age of the sample progressed. While the 180-day electrical resistivity value was 0.04223 kΩm in the REF sample, it reached 0.04755 kΩm in the 30%UK sample and 0.04621 kΩm in the 30% CT sample.
