“…Cement-soil is the commonly used chemical reinforcement method; its compressive strength has been greatly improved in comparison with soil, but it remains a relatively brittle material. Under brittle damage or tension cracking, the strength of cement-soil is reduced abruptly, and it is generally difficult to meet the deformation and stability requirements of engineering under complex stress conditions [7][8][9]. In order to increase the tensile strength and improve the plasticity of cement-soil, a composite reinforcement method combining chemical reinforcement and physical reinforcement by incorporating fibers has emerged in recent years [10,11].…”

In order to realize the resource utilization of solid waste and improve the tensile strength and toughness of soil, CCR-GGBS-FA all-solid-waste binder (CGF) composed of general industrial solid waste calcium carbide residue (CCR), ground granulated blast furnace slag (GGBS) and fly ash (FA) was used instead of cement and combined with polypropylene fiber to strengthen the silty soil taken from Dongying City, China. An unconfined compressive strength test (UCS test) and a uniaxial tensile test (UT test) were carried out on 10 groups of samples with five different fiber contents to uncover the effect of fiber content on tensile and compressive properties, and the reinforcement mechanism was studied using a scanning electron microscopy (SEM) test. The test results show that the unconfined compressive strength, the uniaxial tensile strength, the deformation modulus, the tensile modulus, the fracture energy and the residual strength of fiber-reinforced CGF-solidified soil are significantly improved compared with nonfiber-solidified soil. The compressive strength and the tensile strength of polypropylene-fiber-reinforced CGF-solidified soil reach the maximum value when the fiber content is 0.25%, as the unconfined compressive strength and the tensile strength are 3985.7 kPa and 905.9 kPa, respectively, which are 116.60% and 186.16% higher than those of nonfiber-solidified soil, respectively. The macro–micro tests identify that the hydration products generated by CGF improve the compactness through gelling and filling in solidified soil, and the fiber enhances the resistance to deformation by bridging and forming a three-dimensional network structure. The addition of fiber effectively improves the toughness and stiffness of solidified soil and makes the failure mode of CGF-solidified soil transition from typical brittle failure to plastic failure. The research results can provide a theoretical basis for the application of fiber-reinforced CGF-solidified soil in practical engineering.

Beton teknolojisinde her geçen gün gelişen yeniliklerin uygulamaya girmekte olduğu görülmektedir. Bu makalede beton teknolojisinde son zamanlarda yaygın olarak kullanılmaya başlanmış yeniliklerin bazıları anlatılmıştır. Yeniliklerin bazıları beton üretiminde kullanılan malzemelerle, bazıları ise özellikle gelişen dijital teknolojinin betonlara uygulanmasıyla ilgili olmaktadır. Uygulamada betonların işlenebilirlik, dayanım ve dayanıklılığında oldukça önemli gelişmeler olduğundan bunların ilgilenenlere tanıtılması yararlı olacaktır. Makalede yeni nesil çimento esaslı betonlar başlığı altında sırasıyla, 3D yazıcı ile üretilen betonlar, nano teknolojik ultra yüksek dayanımlı betonlar, kendi kendini ısıtan ve soğutan betonlar, kendi kendini kür eden betonlar, kendi kendini tamir eden betonlar, atık agregalı betonlar, Mars betonu, ultra hafif betonlar, kendini temizleyen betonlar, bükülebilir beton, eko beton (yeşil beton), yarı saydam ve geçirgen beton, nesnelerin interneti (RIFID) teknolojili beton ve çimento bulamacı emdirilmiş lifli betonlardaki (SIFCON) konular hakkında yeni gelişmeler literatüre bağlı olarak açıklanmış, bu yeniliklerin getirdiği avantajlar tanıtılmaya çalışılmıştır.
