With a total of 2 patents, his work has garnered attention for its innovative approaches to enhancing concrete performance.
Latest Patents
One of Allemann's latest patents is for an "Easy-working spray concrete." This invention discloses a spray concrete that remains easy to work with, even at a water-cement ratio of 0.45 to 0.55. It can be sprayed effectively and sets and hardens rapidly. The concrete contains conventional additives along with naphthalinesulfonic acid-formaldehyde condensation products and highly concentrated alkaline aqueous solutions of potassium aluminate, potassium carbonate, and caustic potash. Notably, the concrete displays rapid solidification when it includes up to 3% by weight of alkali silicates or an adequate amount of highly dispersed silicic acid (SiO.sub.2). The additives are preferably incorporated directly at the worksite prior to spraying.
Another significant patent is for a "Liquid accelerator for the setting of concrete mixtures." This invention relates to liquid accelerators that have a long shelf life, even in higher concentrations than previously known liquid accelerators. Within defined concentrations, these new accelerators produce no precipitation. They are characterized by containing only potassium aluminate, potassium carbonate, and potassium hydroxide in a defined range. These accelerators can be used with any known hydraulic binding agents, shortening the set time and improving the compressive strength of the resulting products.
