Title: Stefanie Scheul: Innovator in Cementitious Preparations
Introduction
Stefanie Scheul is a prominent inventor based in Trostberg, Germany. She has made significant contributions to the field of construction materials, particularly in the development of innovative cementitious preparations. With a total of 2 patents, her work focuses on enhancing the properties of concrete and other hydraulic binders.
Latest Patents
One of her latest patents is titled "Aqueous dispersions of silica for increasing early strength in cementitious preparations." This invention involves a dispersion that is free of binders and contains silica along with at least one superplasticizer. The silica used is a precipitated type with a surface area greater than 50 m²/g, and the aggregates in the dispersion have a median diameter of less than 1 µm. The proportion of silica ranges from 5 to 50% by weight, based on the total amount of the dispersion, making it a valuable concrete admixture.
Another notable patent is "Use of block copolymers as dispersants for aqueous suspensions of solids." This patent describes the use of block copolymers, which are synthesized by polymerizing a poly(alkylene oxide) compound with at least one ethylenically unsaturated monomer. These copolymers serve as dispersants for aqueous suspensions of solids, particularly those based on hydraulic binders like cement, lime, gypsum, or anhydrite. Remarkably, these block copolymers exhibit superior water-reducing power compared to conventional superplasticizers, while also reducing slump loss.
