Residual mechanical strength is a necessary parameter in any diagnosis of recovering
structures after fire. Even though concrete is a material traditionally resistant to high …

The effects of polyvinyl alcohol (PVA) fiber content on mechanical and fracture properties of
geopolymer concrete (GPC) were investigated in the present study. Mechanical properties …

The use of manufactured sand as fine aggregate in concrete has been widely adopted in
engineering to alleviate the shortage of natural river sand supply. However, there are many …

The purpose of this study was to assess the performance of introducing polypropylene (PP)
fibers into recycled aggregate concrete containing iron ore tailings (TRAC). Thus, we …

Understanding the porosity/pore linkage and strength properties of cementitious mine
backfill (CMB) is essential for the design of underground mining filling. Adoption of new …

In this study, three-dimensional concrete printing (3DCP) was performed for concrete with
coarse aggregates in air and underwater environments for a comparative evaluation of the …

In the mining industry, backfill is used to stabilize mined-out underground excavations, and
backfill made from mine tailings has the added advantage of being sustainable and …

Sheep wool is an environmentally friendly, renewable, and entirely recyclable resource that
satisfies the standards of green building components. Consequently, it is increasingly …

This study investigated the effects of coarse aggregate and wavy steel fiber volumes on pure
modes I and III fracture toughness (K IF & K IIIF) for which 72 Edge Notched Disc Bend …

For the non-destructive evaluation of concrete properties and internal damage monitoring,
the ultrasonic pulse velocity (UPV) method has been widely employed; however, for coral …
