Özet:

 In recent years, it can be seen that polymer admixtures have gained importance in order to improve the physical and mechanical properties of cementitious products. One of these admixtures is the styrene acrylic copolymer admixture. In this study, the effect of styrene acrylic copolymer SAK use on the performance of cement-based composite mortars, especially the effects of SAK use on the dispersion, unit volume weight, water absorption, bending and compressive strength, shrinkage and swelling characteristics of the mortar, were investigated. According to the study results, as the cement displacement rate with SAK increased, the spread and dry and wet unit volume weight values of the mortars decreased. It has been determined that the most important positive contribution of the use of SAK is that as the rate of SAK usage in mortars increases, the mass water absorption values of the mortars decrease, and their bending strength improves significantly. In addition, it was observed that as the SAK usage rate increased, the compressive strength and swelling values of the mortars decreased, and the shrinkage values increased.

 Son yıllarda, çimentolu ürünlerin fiziksel ve mekanik özelliklerinin iyileştirilmesi amacıyla polimer katkıların önem kazandığı görülebilmektedir. Bu katkılardan önemli bir tanesi de stiren akrilik kopolimer katkıdır. Bu çalışmada, stiren akrilik kopolimer SAK kullanımının çimento esaslı kompozit harçların performansı üzerindeki etkisine, özellikle, SAK kullanımının harçtaki yayılma, birim hacim ağırlık, su emme, eğilme ve basınç dayanımı, büzülme ve şişme karakteristiğine olan etkileri araştırılmıştır. Çalışma sonuçlarına göre, SAK ile çimento yer değiştirme oranı arttıkça harçların yayılma ve kuru ve yaş birim hacim ağırlık değerleri azalmıştır. SAK kullanımının en önemli olumlu katkısı ise SAK kullanım oranı arttıkça harçların kütlece su emme değerlerinin azalması ve eğilme dayanımlarının önemli ölçüde iyileşmesi olarak tespit edilmiştir. Bunun yanında SAK kullanım oranı arttıkça harçların basınç dayanımları ve şişme değerleri azalmış, büzülme değerlerinin ise arttığı gözlemlenmiştir.
