The American Concrete Institute (ACI) published ACI 213R-14, a guide to low-shrinkage high-performance concrete. This report provides a comprehensive overview of low-shrinkage high-performance concrete (LSHPC), including its definition, materials, properties, and applications.

Unlike dense natural stone, lightweight aggregates feature a highly porous internal structure enclosed by a hard outer skin. This structural matrix influences how moisture moves within the concrete mix, giving rise to unique curing advantages. Key Benefits Covered in ACI 213R-14 aci 213r-14 pdf

: Ranges between 1120 and 1920 kg/m³ (70 to 120 lb/ft³).

Aggregates must be pre-conditioned with water prior to batching. Dry aggregates will suck water out of the fresh concrete paste during transit, causing rapid slump loss. (Invoking related search suggestions now

The guide explains the modification factor (

Aggregates must be pre-wetted or pre-conditioned before batching. If dry aggregates are introduced into the mixer, they will suck water out of the fresh paste, causing rapid slump loss and making placement impossible. Pumping LWAC This structural matrix influences how moisture moves within

The guide provides data on the mechanical behavior of structural lightweight concrete:

Because seismic design forces are directly proportional to the mass of the structure, reducing the concrete weight lowers the inertial forces during an earthquake, improving building safety.
