CELLULOSIC PULP INTERNAL CURING AGENT FOR A HYDRAULIC CEMENT-BASED COMPOSITE MATERIAL
A process for preparing a cellulosic pulp for use as an internal curing agent for a hydraulic cement- based composite material is disclosed. The process involves selecting a degree of refining of the cellulosic pulp to cause sufficient fibrillation to provide a change in water retention capacity for the cellulosic pulp while simultaneously limiting a decrease in dispersability within a mixture for forming the composite material due to excess fibrillation. The process also involves controlling refining of the cellulosic pulp using the selected degree of refinement to produce the cellulosic pulp internal curing agent.
A method and apparatus for controlling a cellulosic pulp process for producing a pulp product having a desired pulp property is disclosed. The method involves illuminating an in-process portion of pulp using a first wavelength of light, and receiving a scattered light spectrum from the illuminated portion of pulp, the scattered light spectrum including spectral components that have been shifted in wavelength through interaction with a constituent of the illuminated portion of pulp. The method also involves filtering the scattered light spectrum to separate the spectral components, and identifying spectral features in the filtered scattered light spectrum that correspond to the pulp property. The method further involves generating a control signal for controlling the pulp process based on variations in the identified spectral features to cause the pulp property to fall within a desired range.
