A self-leveling grout provides a level surface for the disposition of a wind turbine base. The self-leveling grout is placed within the foundation grout trough as an initial slurry having a viscosity at ambient temperature approximately the same as the viscosity of known grout slurries utilized in turbine foundations. After placement in the grout trough, elevated temperature is applied to the grout slurry, which lowers the viscosity of the slurry such that the slurry becomes self-leveling and the top surface assumes a nearly perfectly level surface. Additional elevated temperature is applied which initiates the curing of the grout to the required compressive strength for supporting the turbine tower.

A reduced sugar syrup having an advantageously low viscosity is prepared by hydrolysis of starch or starchy material using a particular type of alpha amylase enzyme which yields a saccharide distribution having a low DP1-2 and low DP11+ content. The DP4 content of the syrup may be favorably increased by using a maltotetragenic alpha amylase enzyme in combination with the aforementioned alpha amylase enzyme. The syrup is useful in the production of food, beverage, animal feed, animal health and nutrition, pharmaceutical, and cosmetic compositions and may be combined with a high intensity sweetener to provide a composition capable of being substituted for conventional corn syrups.

The invention belongs to the technical field of phosphorus chemical industry production, and particularly relates to a method for producing phosphoric acid and co-produced gypsum powder by a hemihydrate process. The method for producing the phosphoric acid and co-produced gypsum powder by the hemihydrate process, provided by the invention, is used for solving the problem that co-produced gypsum of the existing hemihydrate processes cannot reach standards of building gypsum. The method provided by the invention comprises the following steps: returning slurry of a crystallizing tank to a pre-reaction tank, and enabling the slurry to make a pre-reaction with phosphorite; in a reaction tank, enabling SO4<2-> remaining in the returned slurry to make a further full reaction with CaO in the phosphorite; adding H2SO4 into the crystallizing tank so as to obtain semi-hydrated gypsum, and carrying out filtrating, washing and free-water removal, thereby obtaining the gypsum powder, of which the length-diameter ratio is (2 to 10): 1. The setting time, breaking strength and compression strength of the gypsum powder prepared by adopting the process are superior to those required in the standards of the building gypsum. The method has the advantages that the energy consumption is lowered, process flows are shortened, the difficulty of subsequent treatment of gypsum produced during the preparation of phosphoric acid by the hemihydrate process is lowered, the range of utilization of ardealite is widened, and the pile-up pressure of gypsum storage yards is lightened.
