An experimental program consisting in producing and testing reinforced concrete pipes (RCPs) under the three-edge bearing tests considering different types of reinforcement was carried out. Four RCPs were produced, these with: (1) polypropylene macrofibers; (2) basalt microfibers; (3) combination both (hybrid reinforcement); (4) plain concrete. The analysis crack patterns service ultimate mecha...

Ancient lunar volcanic deposits, known as cryptomaria, have been detected by remote telescopic and orbital measurements since the 1970s. Cryptomaria are most easily identified by the presence of darkhalo impact craters and are associated with a mare basalt mineralogy, which is indicated by two pyroxene spectral absorption features near 1 μm and 2 μm in the visible to near-infrared (VNIR) wavele...

a preliminary palaeomagnetic results from basalt outcrops in northeast lebanon is reported. the remanence carrier of the characteristic magnetisation is magnetite.  both variations of susceptibility and anisotropy directional data show that the measured directions of thermoremanent magnetisation (trm) are representative of the ambient field at the time of cooling of these basalts through their ...

In recent years, developing lightweight concrete with both the necessary and sufficient strength characteristics is essential in construction industry. This article studies influence of volumetric composition fiber-reinforced (LFRC) method its distribution during preparation fiber–concrete mixture on deformation LFRC a combined aggregate. The optimal grain size porous filler was calculated by m...
