The present invention provides a hydrolysate of a lignocellulosic material, and specifically a method of using a hydrolysis treatment liquid obtained by a hydrolysis treatment of a lignocellulosic material before kraft cooking in order to obtain dissolving pulp for uses other than use of a fuel. Specifically, the present invention provides a dispersant containing the hydrolysate obtained by hydrolysis treatment of the lignocellulosic material. The dispersant of the present invention has excellent dispersibility for a substance such as an inorganic substance and an organic substance without limitation of powder, particulate, granular, fiber, and flat plane shapes.

A slurry for manufacturing gypsum board comprises calcined gypsum, water, a foaming agent, and a coalescing agent. The foaming agent imparts a plurality of bubbles in the slurry. Typically, a foam is pre-generated with the foaming agent and the foam is used to form the slurry such that the foam imparts the plurality of bubbles in the slurry. The coalescing agent coalesces the plurality of bubbles imparted by the foam. Typically, the coalescing agent coalesces a plurality of small and partially joined bubbles imparted by the foam to create larger and more discrete bubbles. A gypsum board and method of forming the slurry and the gypsum board are also disclosed. The gypsum board comprises a gypsum layer formed from the slurry. The gypsum layer defines a plurality of bubbles dispersed therein, which are imparted by the foam and coalescing agent of the slurry.

The invention relates to a cement formulation with two liquid components. This alleviates the problems which result from dust generation where a powdered cement component is employed. Furthermore, the cement may be formed with conventional liquid handling and mixing equipment. The cement binder formulation includes a plasticizer. As the plasticizer is non-volatile, it remains an integral part of both the formulation and the final product obtained after application and drying of that formulation.
