Abstract

Portland cement has been widely used in mortar and concrete construction. However, there are some disadvantages such as, delayed setting time of cement mortar and concrete, low tensile strength, high drying shrinkage, and low chemical resistance. In addition to eliminating these disadvantages, polymers can be used as concrete admixtures to enhance the workability and impermeability of concrete. In this study, fresh and hardened properties of mortars containing different replacement ratios of Styrene-Butadiene Rubber latex by mass (0%, 5%, 10%, 15%, and 20%) at early age (14 days) were examined. The flow and fresh unit weight measurements were made for fresh mortar, while compressive strength, flexural strength, unit weight, water absorption, and capillary water absorption tests were conducted for hardened mortar. As a result, it was observed that the strength decreases as the amount of latex increases in the mortar mixes While a decrease was observed in the flexural strength values due to the use of latex, the use of 10% latex resulted in a small increase of 3% in the flexural strength values of the samples compared to the control mixture. The unit weights of the fresh and hardened mortar samples increased compared to the control sample. The latex addition used has a positive effect on workability, water absorption, and sorptivity of the mortars.

Stiren-Bütadien Kauçuk Lateks Modifiyeli Harçların Erken Yaştaki Fiziksel ve Mekanik Özelliklerinin İncelenmesi

Abstract

Portland çimentosu, harç ve beton yapımında yaygın olarak kullanılmaktadır. Ancak çimento harcı ve betonun gecikmiş priz süresi, düşük çekme dayanımı, yüksek kuruma büzülmesi ve düşük kimyasal direnç gibi bazı dezavantajları vardır. Polimerler bu dezavantajları ortadan kaldırmanın yanı sıra, betonun işlenebilirliğini ve geçirimsizliğini arttırmak amacıyla katkı maddesi olarak kullanılabilmektedirler. Bu çalışmada, Stiren-Bütadien Kauçuk lateksinin kütlece farklı ikame oranlarını (%0, %5, %10, %15 ve %20) içeren harçların erken yaştaki (14 gün) sertleştirilmiş özellikleri incelenmiştir. Taze harç için yayılma ve birim ağırlık ölçümleri yapılırken, sertleşmiş harç üzerinde birim ağırlık, basınç dayanımı, eğilme dayanımı, su emme ve kapiler su emme testleri yapılmıştır. Sonuç olarak harç karışımlarında lateks miktarı arttıkça dayanım değerlerinin azaldığı görülmüştür. Lateks kullanımına bağlı olarak eğilme dayanım değerlerinde düşüş gözlenirken, %10 oranında lateks kullanımı kontrol karışımına kıyasla numunelerin eğilme dayanımı değerlerinde %3 oranında küçük bir artış sağlamıştır. Taze ve sertleşmiş harç numunelerinin birim ağırlıkları kontrol numunesine göre artmıştır. Kullanılan lateks, harçların işlenebilirliği, su emme ve kılcal su emme değerleri üzerinde olumlu bir etkiye sahip olmuştur.
