BS EN 196-11:2018规定了通过等温传导量热法测定不同试验龄期水泥和其他水硬性粘合剂水化热的仪器和程序。本试验程序旨在测量长达7天的水泥水化热,以获得等温传导量热法(ICC)与EN 196-8和EN 196-9之间的对应关系。尽管如此,该试验持续时间对某些仪器来说可能是至关重要的,即使它们可以在较短的试验寿命下正常工作。与EN 196相反-
8.这种方法在一段时间内持续提供水合热。此外,还给出了热流随时间的变化。购买本文件时可获得的所有当前修订均包含在购买本文件中。
BS EN 196-11:2018 specifies the apparatus and procedure for determining the heat of hydration of cements and other hydraulic binders at different test ages by isothermal conduction calorimetry.This test procedure is intended for measuring the heat of hydration of cement up to 7 days in order to obtain correspondence between Isothermal Conduction Calorimetry (ICC) and EN 196-8 and EN 196-9.Nevertheless this test duration may be critical for some apparatus, even if they can work properly at shorter test ages.Contrary to EN 196-8 this method gives the heat of hydration continuously over the time. Additionally, the heat flow versus time is given.All current amendments available at time of purchase are included with the purchase of this document.
