CEMENTITIOUS COMPOSITION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18279952 titled 'CEMENTITIOUS COMPOSITION

Simplified Explanation

The present application relates to a cementitious composition suitable to be applied to an object via a nozzle. The composition comprises a) 15-90% by weight of a cementitious binder, b) 0.02-3% by weight of an ettringite formation controller, c) 0.15-10% by weight of a magnesium salt accelerator and d) 0.02-2% by weight of a polyhydroxy compound A, and/or salts or esters thereof, wherein the polyhydroxy compound A is selected from polyalcohols with a carbon to oxygen ratio of C/O≥1 and mixtures thereof, based on the total dry weight of the composition. Further a process for applying the composition onto a surface and a hardened structure obtained by the process is disclosed.

• The composition includes a cementitious binder, an ettringite formation controller, a magnesium salt accelerator, and a polyhydroxy compound A, providing unique properties for application via a nozzle.
• The polyhydroxy compound A is selected from polyalcohols with a specific carbon to oxygen ratio, enhancing the performance of the composition.
• The process for applying the composition onto a surface allows for efficient and effective application, resulting in a hardened structure with desirable characteristics.
