This paper introduces a 1-D finite difference model for analyzing the temperature distribution throughout the hardening phase in concrete structures. The model accounts for the degree of hydration-dependent internal heat rate and the solar irradiance

Early-age cracking during the plastic stage is unsightly and a cause of future durability problems. This paper investigates the effects of various simple curing methods used in practice to enhance early-age concrete cracking performance, including co

Self-desiccation-induced shrinkage may result in cracking at an early age, which is averse to the durability of concrete. Internal curing (IC) agents, such as superabsorbent polymers (SAP), are normally used for moisture regulation and shrinkage redu

Concrete structures are prone to cracking due to non-uniform temperature distribution caused by the heat released during cement hydration. Accurate prediction of temperature evolution is crucial for the design and control of concrete temperature in c

Rock-filled concrete (RFC) is a highly heterogeneous material composed of rock blocks and self-compacting concrete (SCC). There is still limited literature regarding the non-uniform thermal behavior of early-age RFC, making it difficult to predict eq

Due to the large amount of binder and low water-cement ratio, high-performance cement composites have high compressive strength and a dense hardened cement paste microstructure. External curing is insufficient, as it cannot reach the interior parts o

Fire accidents happen randomly which may occur in the construction of concrete buildings. In this study, the effects of high temperature and curing ages on shear properties of early-age concrete were experimentally studied. The pore structure of earl

Short-term uniaxial tensile creep tests were conducted for early-age concrete at different ages in an effort to characterize early-age concrete as an aging viscoelastic material. Based on the test results, the viscoelastic material properties of the
