Abstract: Embodiments of a system and a method for measuring cementitious board during its continuous manufacture can be used online in a continuous manufacturing process to effectively determine the degree to which cementitious slurry has set (e.g., expressed as percent hydration) at a predetermined location, such as, near a cutting station, for example. A compression assembly can be used to compressively engage the cementitious board in a controlled manner as it passes by the compression member along the conveyor between the forming station and the cutting station. A force gauge can be associated with the compression member to measure the resistance force exerted by the cementitious board in response to being compressed by the compression member. The resistance force can be correlated to a set characteristic of the cementitious board, such as a numerical value of percent hydration of the cementitious slurry of that particular portion of the cementitious board.

Abstract: Embodiments of a system and a method for determining an edge hardness value for a cementitious board can be used to effectively determine the hardness of the board after it has been made and dried at a predetermined location, such as, at a stacking station, for example. An actuator assembly can manipulate a punch such that the punch is inserted into one of the edges of one of the cementitious boards in the stacker in a controlled manner. A force gauge can be associated with the punch to measure the resistance force exerted by the cementitious board in response to the punch being inserted into its edge. The measured resistance force can be used to determine the edge hardness value.
