Open AccessImproving bond strength and mass transport properties of spacer-concrete interface with textured spacers
Spacers are important devices used in all concrete structures to support reinforcing steel and achieve the required cover. However, spacers induce a weak, porous and microcracked interface that facilitates ing...

Open AccessMicroscopy techniques for determining water–cement (w/c) ratio in hardened concrete: a round-robin assessment
Water to cement (w/c) ratio is usually the most important parameter specified in concrete design and is sometimes the subject of dispute when a shortfall in concrete strength or durability is an issue. However...
