The materials were mixed according to the mix proportions in Table 3, and specimens cast (4 × 4 × 16 cm 3) at room temperature (25 °C). During the delay period before heat curing, the specimens were covered with polyethylene sheets and kept at 25 °C at a relative humidity (RH) >95% for 3 h.The curing regime is shown in Fig. 2.The heat curing was …
Lightweight aggregate (LWA) has been used in concrete for a long time, but its internal curing (IC) effect has been realized recently. This paper offers a review of LWA as internal curing materials for high performance cement-based materials. The effect of LWA on IC is related to its amount, pretreatment method, particle size, and distribution ...
