Sample Placement Effect During Curing on Microwave Reflection Properties of Early Age Engineered Cementitious Mortar Specimens

Microwave reflection properties of early age (one to nine days) engineered cementitious mortar specimens with a different water-to-binder ratio ( $w/b$ ) and different sample placements during curing were measured by an open-ended waveguide probe, and then, the effect of these curing conditions on microwave reflection properties was investigated. From this analysis, we note the following important...
