Abstract
The invention relates to a cement formulation with two liquid components. This alleviates the problems which result from dust generation where a powdered cement component is employed. Furthermore, the cement may be formed with conventional liquid handling and mixing equipment. The cement binder formulation includes a plasticizer. As the plasticizer is non-volatile, it remains an integral part of both the formulation and the final product obtained after application and drying of that formulation.
Claims16
A kit-of-parts for preparing an adhesive and/or sealing formulation comprising:
- a) a hydraulic binder module being a storage-stable, liquid composition comprising:
- a hydraulic binder including a mixture of gypsum, Portland cement, and aluminate cement, and
- an anhydrous liquid, where the anhydrous liquid has a boiling point greater than 175° C. at 1 atmosphere pressure and is inert towards the hydraulic binder, wherein the anhydrous liquid is a plasticizer that remains an integral part of both the adhesive and/or sealing formulation and the final product obtained after application and drying of the formulation;
- and
- b) an aqueous liquid module, wherein the aqueous liquid module comprises water and a polymer dispersed therein, and the amount of water comprised in the aqueous liquid module is in the range of from about 30 to 60 wt. %, wherein said dispersed polymer has a glass transition temperature (Tg) of from −40° to 70° C.
A kit-of-parts for preparing an adhesive and/or sealing formulation comprising:
