(308-213)R-13 Report on Internally Cured Concrete Using Prewetted Absorptive Lightweight Aggregate
| Published By | Publication Date | Number of Pages |
| ACI | 2013 | 16 |
This report introduces the concepts of and describes the process benefit and applications for using prewetted lightweight aggregate to increase cement hydration in internally cured concrete. It also describes mixture proportioning and absorptive material selection and discusses the benefits relating to sustainability. The materials, processes, quality control measures, and inspections described should be tested, monitored, or performed as applicable only by individuals holding the appropriate ACI certifications or equivalent. Keywords: absorption; curing; desorption; durability; high-performance concrete; hydration; internal curing; internally cured concrete; lightweight aggregate; outside curing; permeability; saturated-surface-dry; shrinkage; strength; supplementary cementitious materials; water movement.
