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.

The pouring of latex modified concrete can be done in warm or even hot weather conditions. The latex modifier is treated and kept in a hot condition to let the modified concrete go into final setting, and also kept hot to allow the concrete to cure. Hot water is added to the concrete, while keeping it hydrated. The poured latex modified concrete can be broom finished to provide suitable surface finish. A false atmosphere can be created at the point of placement of the latex modified concrete, as well as at the point of production. This false atmosphere will interact with a controlled temperature modified product to cure.
