在冬季混凝土施工中采用热水拌和并掺入低温早强剂是提高混凝土早期强度和防止混凝土早期受冻的有效措施。然而,混凝土拌和物的温度过高,一方面会使其坍落度损失加快,特别当掺有低温早强剂时尤甚;另一方面因其与气温的温差较大,热能损耗加剧,功倍事半。根据日本和美国的资料认 The use of hot water mixing and incorporation of low-temperature early-strengthening agent in winter concrete construction is an effective measure to improve the early strength of concrete and prevent early freezing of concrete. However, if the temperature of the concrete mix is ​​too high, slump loss will be accelerated on the one hand, especially when a low-temperature early-strength agent is added. On the other hand, due to the large temperature difference between the concrete and the temperature, the heat loss is increased. Half the time. Based on data from Japan and the United States
