Abstract
The sprayed concrete complies a construction technique that combines the placement and the compacting of concrete in only one process. This sort of concrete, which is widely used in underground constructions, requires a quick setting obtained by using set accelerating admixtures. Due to the function performed by these admixtures during the hydration process of the concrete, an analysis of its mechanical properties at early ages is essential. The European Standard ‘EN 14488-2:2007 - Testing sp...
