Silindirle sıkıştırılmış betonların (SSB), geleneksel betonlara kıyasla üretiminin hızlı olması, maliyetinin düşük olması ve daha iyi dayanıklılık performansı göstermesi nedeniyle günümüzde yaygın olarak tercih edilmektedir. SSB karışımları hava limanları, fabrikalar, petrol istasyonları, çeşitli endüstriyel zeminler ve özellikle barajlar, yollar gibi birçok alanda uygulanmaktadır. Bu çalışmada SSB uygulamalarının avantaj, dezavantaj, tarihçesi, mekanik ve durabilite özellikleri üzerine yapılan araştırmalar ayrıntılı olarak incelenmiştir. Mekanik özellikler kapsamında uçucu kül, yüksek fırın cürufu, çelik ve polipropilen lifler, geri kazanılmış malzemeleri içeren SSB karışımların basınç, eğilme dayanımı, çekme dayanımı, elastisite modülü, yorulma davranışı ve sünme performansı araştırılmıştır. Durabilite performansı olarak SSB karışımların yoğunluk özellikleri, geçirgenlik, boyutsal kararlılığı, donma-çözülme direnci ve termal özellikleri kapsamında literatürde yapılan çalışmalar incelenmiştir.

“…Ketcheson et al studied the effect of road salt (sodium chloride) on water and chloride movement in pervious concrete structures in a laboratory environment [23]. Nili et al evaluated the salt resistance of long and short freezing period samples under freeze–thaw cycles [24]. Throughout the current research on the state of layer-to-layer contact there is a main focus on influencing factors.…”

The contact state between layers of asphalt pavement not only has a significant effect on the mechanical response of road structure but is also the bottleneck of research on the mechanical behavior of pavement structure at present. In this paper, the effects and laws of different water–salt entry modes, salt solution concentrations, and temperatures coupling on the contact state between base and surface layers are studied by a 45° inclined shear test. The simulation and verification of each working condition are carried out by ABAQUS (Dassault, Paris, France) the friction coefficient between layers is reversed, and the actual contact state between layers is characterized in order to realize comprehensive evaluation and reasonable expression. The results show that different modes have different effects on contact characteristics. At the same temperature and concentration of the salt solution, bonding of water and salt erosion is the best, followed by direct erosion, with the worst being from bottom to top, and the interlayer bonding condition is weakened with increase in temperature. The relative accuracy of the software simulation and test analysis was as high as 92% and the friction coefficient of the water-free salt erosion test piece was found to be about 0.85 at 25 °C, while after the bottom-up erosion of the 14% salt solution the friction coefficient was found to be about 0.43, which indicates that the corrosion of the water–salt will have a great effect on the bonding condition between the structural layers of the road.

“…Fiber plays a role in the following three aspects: crack arrest, strengthening and toughening [4][5][6][7] . Therefore, comparing with plain concrete there are different degrees of improvement in crack resistance [3,[8][9] , bending resistance, impact resistance and anti-fatigue properties for the fiber concrete which are widely used in various fields of bridges, airports, highways, tunnels, water conservancy [10][11][12] .…”

Fiber is capable of improving the corrosion resistance and freeze-thaw durability of concrete of airport deicing platform. After 300 freeze-thaw cycles, the relative dynamic modulus of plain concrete is reduced to 73.46%, and the relative dynamic modulus of fiber concrete is about 80%, that is, the fiber has a positive influence on the frost resistance of concrete. In addition, the durability of fiber reinforced concrete is better than that of plain concrete under the same test conditions as the corrosion cycles and freeze-thaw cycles.
