Abstract

This study investigates the effects of efficient crack resistant agent (HME®-V) with different dosage levels (0, 5%, 10%, 15%) on the fresh properties, mechanical properties and chloride ion penetration resistance of mass concrete. Hydration heat tests, XRD analysis and numerical simulation were carried out to simulate the hydration heat of concrete blocks, so as to reveal the influence mechanism of efficient crack resistant agent on the hydration heat of mass concrete. The results indicate that with the addition of efficient crack resistant agent, the slump and setting time of concrete are gradually increased. The exothermic process in the acceleration period of cement hydration is prolonged, the temperature peak is weakened, the hydration heat release rate is reduced, and the total hydration heat is decreased. Meanwhile, the temperature rise rate and peak temperature at the core point of concrete blocks first decrease and then increase with the increase of agent dosage. Among them, when the efficient crack resistant agent content is 10%, the inhibition effect on hydration heat is the most significant, which can effectively control the temperature drop rate and reduce the risk of thermal cracking. In addition, the temperature rise rate and peak temperature at the core point of concrete blocks reach the lowest values, and the concrete exhibits better slump, consistency and workability, which can better meet the requirements of practical construction performance.
