Latest Patents

Hasegawa holds a patent for a "Glazed cement product and method for manufacturing thereof." This invention outlines a method for producing glazed cement products using a foam lightweight aggregate, reinforcing steel under pretension, or a stress-absorbing layer around the reinforcing steel. The method addresses the issue of crack generation caused by the difference in the coefficient of thermal expansion between the reinforcing steel and the cement material during the burning and cooling processes. The foam lightweight aggregate, stress-absorbing layer, or pretension applied to the reinforcing steel effectively absorbs these stresses. Additionally, the hydration process promotes the reaction of unreacted cement components, enhancing the mechanical strength of the final product.
