En cualquier obra de construcción resulta de suma importancia determinar la resistencia del concreto utilizado. Para esto es necesario tomar testigos estandarizados para obtener ese valor de resistencia. La prueba se denomina "Ensayo para determinar la resistencia a la compresión del concreto", consiste en aplicar una fuerza axial sobre los cilindros previamente tomados en obra, con una prensa hidráulica hasta lograr la rotura del espécimen, un lector de presión muestra la fuerza aplicada al momento de la falla por compresión.
