Bu çalışma, sodyum klorür (NaCl) etkisi altındaki diatomit ikameli betonların performansını araştırmak için yapılmıştır. Bu amaçla diatomit sırasıyla, %0, %10 ve %20 oranlarında Portland çimentosu yerine ikame edilerek üç farklı çimento elde edilmiştir. Tahribatlı ve tahribatsız deneyler için bu çimentolarla üretilmiş toplam 54 adet 15x15x15 cm ebadında küp numuneler üretilmiştir. Üretilen sertleşmiş beton numuneleri üzerinde birim ağırlık, su emme oranı, görünür boşluk oranı, ultrases geçiş hızı, kapiler su emme, yarmada çekme dayanımı ve basınç dayanımı deneyleri yapılmıştır. Bu deneyler, üç farklı beton türü üzerinde, 28 gün 23±2 oC suda, daha sonra NaCl ve beton yaşı faktörünün iki düzeyinde (56 ve 90 gün) kür edilen beton numuneleri üzerinde gerçekleştirilmiştir. Sonuç olarak, sertleşmiş beton numunelerinin basınç dayanımı, yarmada çekme dayanımı, ultrases geçiş hızı, kapilerite katsayısı, görünür boşluk oranları, su emme oranları ve birim hacim ağırlıkları deneylerinin tümünün birbiri ile uyumlu olduğu belirlenmiştir.
This study was done to investigate the performance of diatomite stainless concrete under the effect of sodium chloride (NaCl). For this purpose, three different cements were obtained in place of Portland cement, respectively, at the rate of 0, 10% and 20%. A total of 54 cubic samples of 15x15x15 cm, produced with these cements for damaged and undestroyed experiments, were produced. Unity weight, water absorption rate, visible empty rate, ultrasound transition speed, capilla water absorption, drawing resistance and pressure resistance tests have been performed on the produced solid concrete samples. These experiments were carried out on three different types of concrete, 28 days in 23±2 oC water, then on two levels of NaCl and concrete age factor (56 and 90 days) curved concrete samples. As a result, hardened concrete samples have been determined that the pressure resistance, drawing resistance, ultrasound transition speed, capilarity ratio, visible emptiness rates, water absorption rates and unit volume weights tests are all compatible with each other.
This study was designed to investigate the performance of diatomite-substituted concretes under the effect of sodium chloride (NaCl). For this purpose, diatomite was substituted for Portland cement at 0%, 10% and 20% and three different cement were obtained. For these destructive and non-destructive tests, a total of 54 units of 15x15x15 cm cube samples were produced. On samples of produced hardened concrete unit weight, water absorption, porosity, capillary water absorption, ultrasonic velocity, splitting tensile strength and compressive strength experiments have been done. Hardened concrete tests have been done on three different types of concrete, for 28 days, in 23±2 oC water, then on the concrete samples which are cured NaCl of the media factor and in the level 2 (56 and 90 days) of concrete age factor. As a result, it was determined that the compressive strength, splitting tensile strength, ultrasonic velocity, capillary water absorption, porosity, water absorption and unit weight of the cured concrete specimens were in coherent with each other.
