英文名称:Testing of concrete — Part 14: Setting time of concrete mixtures by resistance to penetration

发布日期:2019-11

标准范围

This document 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.
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 setting and hardening characteristics 
of concrete.
This test method is applicable under controlled laboratory conditions, as well as under field conditions.
