New possibilities of applying structural interpretation of density image for geonavigation of wells
Известия высших учебных заведений: Нефть и газCurrently, tools such as density imagers are not fully utilized in geonavigation of wells. The authors of this paper propose that the angles and directions of layering obtained through the structural interpretation of density imager data in horizontal ...

Structural Concrete, EarlyView.Abstract Lightweight strain‐hardening ultra‐high‐performance concrete composite (SH‐UHPC) is an outstanding alternative for engineering applications and infrastructure thanks to its outstanding strength, toughness, ductility, and low density. The integration of artificial intelligence (AI)‐based modeling strategies into engineering problems can ...

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete
Structural Concrete, EarlyView.Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...
