水泥混凝土施工已普遍应用于各类建筑工程中。混凝土的塑性、流动性随着时间的推移会逐渐变稠、硬化，逐渐产生强度，混凝土坍落度损失是目前混凝土搅拌站以及公路工程建设中普遍遇到的一个技术难点。坍落度指新拌水泥混凝土拌和物在自重下的下沉量，是衡量混凝土的和易性、保证施工正常进行的重要参数。包括混凝土的棍度、含砂情况、流动性、粘聚性和保水性。混凝土“坍落度损失”是指集中搅拌站拌制水泥混凝土时的坍落度与运至施工现场的混凝土坍落度之差值。坍落度损失过大有时会严重干扰施工的正常运行，因此，控制坍落度损失是工程施工的重要任务。

Cement concrete construction has been widely used in various construction projects. The plasticity and fluidity of concrete will gradually thicken and harden with the passage of time, and gradually produce strength. At present, the loss of concrete slump is a common technical difficulty in the construction of concrete mixing plant and highway engineering. Slump refers to the settlement of fresh cement concrete mixture under self weight, which is an important parameter to measure the workability of concrete and ensure the normal construction. It includes the degree of concrete stick, sand content, fluidity, cohesion and water retention. "Slump loss" of concrete refers to the difference between the slump of cement concrete mixed in the central mixing plant and the slump of concrete transported to the construction site. Too much slump loss sometimes seriously interferes with the normal operation of construction, so it is an important task to control the slump loss.<br>
