Title: Innovations of Samuel E. Graham in Cement Reinforcement
Introduction
Samuel E. Graham, an innovative inventor based in LaGrange, Georgia, has made significant contributions to the field of cement reinforcement. With a total of three patents to his name, Graham’s work focuses on enhancing the properties and durability of cementitious materials through advanced fabric technology.
Latest Patents
Graham's latest patents revolve around the concept of fabric reinforced cement. One of his notable inventions involves a cementitious article reinforced with fabric comprised of high modulus polyolefin monofilament fibers. This innovation highlights the use of polypropylene monofilament yarns that possess a 3% secant modulus of elasticity of at least 100 g/denier. The high modulus polypropylene fabric is particularly suited for cementitious composites due to its intrinsic resistance to alkaline conditions, paired with low elongation at break.
Another significant patent details a cement panel reinforced with a fabric made of nucleated polypropylene fibers. This panel consists of a lightweight cement composition core, which is encapsulated by layers of reinforcing nucleated polypropylene fabric on both the top and bottom. These layers are bonded to the core using a coating of cementitious material, while the edges of the panels feature overlapping fabric layers to enhance strength.
