Özet:This thesis work aims to research the possibility of acceleration in strength development by the use of Calcium Nitrate (Ca(NO3)2) and Triisopropanol Amine (TIPA) in the production of glass fiber reinforced concrete, also known as GFRC or GRC. In conventional cementitious systems, Ca(NO3)2 is used as an accelerator, and TIPA is typically used as a grinding agent for cement. In this thesis study TIPA is used in order to increase the ultimate strength of the concrete whose early strengths are increased by Ca(NO3)2. In order to achieve the goal, the required values of the admixtures were prepared and their 6 h compressive and flexural strength were measured. Also their strength development in 7 and 28 days were noted. The results revealed that TIPA could be used to increase the ultimate strength of GRC. The use of 0.05-0.1% TIPA and 6-8% Ca(NO3)2 is suitable for gaining the highest early and ultimate strengths
