Concrete Products: Why Structural Lightweight Concrete

ESCSI Member Darren Medeiros authored an article featured in Concrete Products answering key questions about structural lightweight concrete (SLC) in mix design. Read an excerpt below.

When designing concrete mixes for bridges and other structures, project engineers have multiple options—including choosing between traditional, normal weight concrete (NWC) or structural lightweight concrete (SLC) with aggregate meeting ASTM C330, Standard Specification for Lightweight Aggregates for Structural Concrete performance. Depending on a project’s goals, SLC can create stronger, more resilient and cost-effective structures.

But there may be some questions about what makes SLC different and how this category of concrete contributes these benefits to load-bearing construction.

This article addresses common questions on designing an SLC mix for use in construction projects.
