Early age temperature effect of cemented sand and gravel based on random aggregate model
Source abstract
Abstract
Abstract This study investigates the risk of early-age cracking in cemented sand gravel by modeling it as a two-phase material (aggregate and mortar) from a mesoscopic perspective. A mathematical model incorporating mesoscopic components was developed to simulate the temperature stress field under different heat dissipation conditions. Key findings include: (1) Early-age heat release occurs primarily in the mortar, leading to uneven temperature distribution (low in aggregate, high in mortar), which becomes uniform as hydration ends. Stress concentration is observed at aggregate–mortar interfaces. (2) Mesoscopic component consideration reveals local stress concentration, unlike models ignoring meso-components. (3) External heat dissipation conditions significantly affect temperature effects. Under adiabatic conditions, larger deformations occur at mortar–aggregate intersections and increase over time. In heat dissipation states, deformation is higher at boundaries, unevenly distributed, and decreases over time. This research highlights the importance of mesoscopic considerations in understanding and mitigating early-age cracking risks in cemented sand gravel.
