Sentetik zeolitlerin çimentolu sistemlerde kullanılması

Day after day the field of cement replacement materials keeps improving and new discoveries come out. Natural pozzolans, fly ash and blast furnace slag are good examples for those materials. However, for many reasons the look for a new material to be used never ends. Synthetic zeolite, a modified type of zeolite, is generally used as an adsorbent for its porous types. The original material, zeolite itself, is known for its reactivity with cement, and since synthesizing zeolite provides a better controlled product (it is cleaner and its particles are much more uniform in size) it is expected to be more reactive. In this work synthetic zeolites of different sizes and compositions are incorporated in cement mortars. The effects of this use on the fresh properties (consistency and setting time) and hardened properties (compressive strength and porosity) of the cement mortars will be investigated. Moreover, to understand the effect of the synthetic zeolite on the hydration process of the cement, paste specimens will be prepared and then examined under scanning electronic microscope and analyzed by XRD and XRF methods. The test results are expected to give a better understanding about the reaction mechanism between cement and synthetic zeolite, and help to improve it
