摘要
Research directed at developing a new composite expansive additive for use in producing shrinkage-compensating cement by addition to Portland cement is reported. Setting time, flow loss, free expansion, restrained expansion and compressive strength results were obtained for cement pastes and mortars containing different amounts of expansive additive. The effect of superplasticizer on the properties of fresh and hardened expansive cement mortar was also investigated. Results indicated that expansive cement with an appropriate amount of pre-hydrated high alumina cement based expansive additive passes all the requirements of relevant ASTM standards and is potentially of practical use.
