Effect of Internal Curing on Moisture Gradient Distribution and Deformation of a Concrete Pavement Slab Containing Pre-Wetted Lightweight Fine Aggregates
Internal curing technology has been proven effective in improving many properties of concrete. The application of this technology to the transportation infrastructure holds promise with increasing resistance to cracking and enhanced durability. On the other hand, an investigation of moisture distribution in concrete slabs is of significance for predicting slab deformation and the associated stress and failure. This study is performed to investigate the characteristics of the pre-wetted sintered fly ash lightweight fine aggregate (LWFA) used as an internal curing agent and the influence of internal curing on concretes exposed to sealed curing, external drying, and surface wetting conditions. The internal curing effects on the moisture distributions in concrete pavement slabs at w/c = 0.3 and 0.4 were evaluated through experimental measurements, and the effects on slab deformations were quantified using an equivalent temperature difference. The findings of this study will benefit the further application of internal curing technology to the transportation infrastructure's construction.
