LJ143混凝土泵送剂是一种集高减水、缓凝、引气、增强于一体的复合型多功能混凝土外加剂。应用LJ143混凝土泵送剂可配制C60泵送混凝土,也可与混凝土膨胀剂复合使用弥补因掺入混凝土膨胀剂而引起泵送混凝土坍落度损失太快的缺点,且混凝土强度和抗渗性能不降低;此外,单掺LJ143混凝土泵送剂可以现场搅拌配制C70混凝土。 本文论述了LJ143混凝土泵送剂的研制及其在C60泵送混凝土中应用和地下防水工程中与混凝土膨胀剂的复合使用。
LJ143 concrete pumping agent is a compound multi-functional concrete admixture that combines high water reduction, retardation, bleed air, and reinforcement. LJ143 concrete pumping agent can be used to formulate C60 pumped concrete, and can also be combined with concrete expansion agent to make up for the shortcomings of the slump loss of pumped concrete caused by the incorporation of concrete expansion agent, and the concrete strength and impermeability are not In addition, the single-blended LJ143 concrete pumping agent can be used to mix C70 concrete on site. This article discusses the development of LJ143 concrete pumping agent and its use in C60 pumped concrete and underground waterproofing projects in conjunction with concrete expansion agent.
