Lightweight Concrete Study - ESCSI

The normal weight control concrete slab reported in this study was batched to a w/c of 0.50 and placed on April 16, 2009. The lightweight control concrete slab reported in this study was batched to a w/c of 0.50 using lightweight aggregate with an absorbed moisture content of 23.6%. The lightweight slab was placed on April 22, 2009. Table 8.

ESCSI - Lightweight Aggregate - ESCSI

Brief History of ESCS and ESCSI. For over a century, ESCS has been used successfully in more than 50 different types of applications. The most notable among these are lightweight concrete masonry units, high-rise buildings, concrete bridge decks, high performance marine platforms, asphalt bituminous surface treatments, lightweight chip seal, soil conditioner and lightweight geotechnical fills.

Engineer’s Corner: Myths and Misconceptions #2 - ESCSI

In response to the trend to abandon use of lightweight concrete for elevated slabs, ESCSI sponsored a study by Craig (2011) to more closely study the drying of lightweight concrete slabs. The first phase of the study examined the drying behavior of three deck slabs that were representative of elevated slabs constructed in steel-framed buildings.
