“…The compressive, tensile, and flexural strength of M35 grade concrete decreased by about 20 %, 47 %, and 33 % respectively compared to the control concrete. Consequently, the use of crumb rubber is only recommended at an optimal level as it causes the strength to drop [8][9][10]. The percentage of waste admixture in this study is not clearly mentioned, it is not known at what percentage there is a decrease.…”

According to the national standard body in Indonesia, the compressive strength of 20 MPa concrete is medium quality concrete. Medium-strength concrete is usually used for floors, light construction, houses, warehouse factories, and sidewalks. The use of medium-strength concrete is very broad, it is necessary to continuously conduct research to produce new innovations. Previous research on the utilization of waste rubber tires has been carried out. Research on the development of concrete with the use of waste tire rubber powder is very interesting to do considering the waste of used tires that continues to increase along with the increase in the number of motorized vehicles in Indonesia. Portland Cement (OPC) and Portland Pozzolan Cement (PPC) are the two types that will be used in this research to see its effect on concrete with waste rubber powder. These two cements also have different corrosion resistance. And seawater is one of the triggers of high concrete corrosion.

These two cements also have different corrosion resistance. And seawater is one of the triggers of high concrete corrosion. This study aims to analyze how the compressive strength of PPC concrete compares with OPC and the addition of used tire powder under seawater treatment conditions. Six concrete variants were made and then tested for compressive strength. The compressive strength values of variants 1 to 6 were obtained as 20.78 MPa, 18.26 MPa, 19.56 MPa, 16.58 MPa, 13.03 MPa. The results show that tile powder is not effective in increasing construction strength, but the use of PPC cement is more effective than the use of OPC in improving construction, especially for cement use in buildings close to sea water

“…Despite the promising advantages offered by utilizing rubberized concrete, previous studies have reported some drawbacks and limitations [31][32][33][34][35][36]. In a study by Eshmaiel Ganjian [37], coarse aggregates were partially replaced with chipped tires of comparable grading size to the original aggregate, at varying weight percentages (5%, 7.5%, and 10%).…”

In recent years, the alarming number of terrorist attacks has highlighted the critical need for extensive research aimed at fortifying structures against explosion-induced loads. However, the insufficient energy absorption and brittleness of conventional concrete make it ineffective in withstanding blast loading, encouraging researchers to explore innovative strategies for augmenting the energy dissipation capabilities of construction materials. This study specifically delves into the incorporation of recycled rubber, a sustainable and environmentally friendly solution to the pressing issue of scrap tire disposal. The primary focus of this research revolves around the integration of rubber recycling and steel fibers into concrete, with the ultimate goal of enhancing the dynamic response of reinforced concrete (RC) beams. This novel approach not only contributes to the structural resilience required for resisting blast impacts, but also aligns with eco-friendly practices by reusing recycled rubber. A meticulous numerical investigation was undertaken to comprehensively assess the static and blast response of these augmented beams. The numerical study involved developing finite element (FE) models using ABAQUS version 6.14 for static implicit analysis and LS-DYNA R11 for blast explicit simulations. The ABAQUS model was validated against previous experimental testing for load–displacement and failure patterns. Similarly, the LS-DYNA model was validated for blast pressure in accordance with UFC-3-340 standards and for material response under blast loading, utilizing existing experimental data. The numerical models were designed to accommodate varying weight percentages of rubber, ranging from 5% to 20%, and a consistent 1.0% incorporation of steel fibers. This comprehensive analysis aims to provide valuable insights into the efficacy of these materials in improving the structural integrity and blast resistance of RC beams, thereby contributing to the development of more secure and sustainable construction practices. By reducing the reinforcement ratio in order to meet the minimum code requirements, it became evident that the failures of the rubberized RC beams tended to exhibit ductility on the tension side under static loading. In addition, the increase in the reinforcement ratio correlated with a higher failure load and decreased deflection. Furthermore, the findings indicated an optimal concrete mixture characterized by improved ductility, energy absorption, and blast load capacity, achieved by combining 5–10% rubber with steel fibers.

Çeşitli atıkların harç ve beton içinde kullanımı son zamanlarda yaygınlaşmıştır. Büyük miktarda çevresel kirliliğe sebep olan otomobil lastiklerinin beton içinde kullanımı da bunlardan biridir. Lastiklerin betonda kullanımıyla betona ait pek çok özelik geliştirilmektedir. Lastikli betona ait özeliklerin farklı yöntemlerle analizi ve modellemesi yapılmaktadır. Bu çalışmada ise lastikli betonların süspansiyon teorisi ile analizi yapılmaya çalışılmıştır. Birim ağırlık, basınç dayanımı, eğilme dayanımı ve ultrases geçiş hızı deneysel sonuçlarından elde edilen verilerinden alınan değerler süspansiyon teorisi formülünde yerine konularak "k" değerleri hesaplanmıştır. Hesaplanan "k" değerleri matris ve dağılı fazın E-modül değerlerine, tane boyutlarına, tane yüzey ve şekline bağlı olarak elde edilen bir boyutsuz değerdir. Bu çalışmada beton içerisine katılan atık lastiklerin yüzdelerine göre değişen birim ağırlık, basınç dayanımı, eğilme dayanımı ve ultrases geçiş hızlarına göre elde edilen k değerleri tablo ve grafikte gösterilmiş ve elde edilen sonuçlar yorumlanmıştır. Kuru birim ağırlık, basınç dayanımı, eğilme dayanımı ve ultrases geçiş hızı için "k" değerleri sırasıyla-0.039 ile -0.187, -0.137 ile -3.553, -0.778 ile -1.939 ve -0.098 ile -0.922 arasında değişen değerleri almaktadır.
