- What is ISO 1920 ‑ 14 - Testing of concrete about? ISO 1920-14 discusses making, and curing test specimens for testing concrete. Concrete is used to provide strength, durability, and versatility during the construction of a structure. ISO 1920 ‑ 14 is the 14 th part of the ISO 1920 series, that covers the method for determining the setting time of concrete with slump greater than zero, by testing mortar sieved from the concrete mixture. The initial setting time, and the final setting time are the time intervals required for the mortar sieved from the concrete mixture to reach the specified values of penetration resistance after the initial contact of cement, and water. In ISO 1920 ‑ 14 , the method can be used for determining the effect of variables such as temperature, type, and content of cement, concrete mix proportions, and admixtures, on the time of se...
