泵送混凝土需要掺加适量的泵送剂来改善混凝土拌合物的工作性,达到顺利泵送的目的。但是,由于原材料的不稳定,泵送剂的不稳定,就会造成混凝土拌合物的离析,导致混凝土在泵送时堵管,混凝土强度降低,甚至造成质量事故。为了杜绝这一通病的发生,需要制定预防措施予以控制。本文就预防措施予以讨论。 Pumping concrete requires the addition of an appropriate amount of pumping fluid to improve the workability of concrete mixes for smooth pumping. However, due to instability of raw materials, pumping instability, it will cause segregation of concrete mix, resulting in concrete plugged in pumping, concrete strength decreased, and even cause quality accidents. In order to prevent this common problem, we need to develop preventive measures to control. This article discusses preventive measures.
