    摘要： Method for producing an aqueous suspension, which is based on a hydraulic binder, and a hardened binder product. According to the invention, a composition of blending agents is added in the aqueous phase into the binder, which composition comprises calcium carbonate particles having an average particle size of 2-200 nm, in order to generate an aqueous suspension and, if needed, mineral fillers are added into this suspension, in order to produce a hardening plaster or concrete mixture. Besides calcium carbonate, the composition of blending agents can comprise calcium hydrogen carbonate and meta-kaolin sinter, too. By using the present invention, it is possible to improve the properties of products which are bound by hydraulic binders; with the described combination of blending agents it is possible to affect for instance the early strength, the frost resistance, the phenomenon of bleading, the plasticizing, the size of the transition zone and the durability of concrete or plaster, and to reduce the quantity of the hydraulic binder.

    摘要： According to the process, limestone is burned at a high temperature to form calcium oxide and, thereafter, calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered. The formation of the carbonate may be performed by carbonating calcium oxide with carbon dioxide gas in the presence of water or water vapour, or by reacting calcium oxide with soda solution. According to the invention calcium oxide is converted to calcium carbonate without separate slaking and essentially without intermediate storage, in particular without intermediate storage between the burning of the starting material and the forming of calcium carbonate. With the aid of the invention a quite advantageous solution in view of heat economy is achieved.

    摘要： The invention is related to a method for forming calcium carbonate. In the method, calcium oxide is reacted with carbonate ions in the presence of water to produce calcium carbonate. According to the invention, the formation is carried out directly from calcium oxide to calcium carbonate without intermediate stages in a three-phase precipitation, whereby the hydration of the calcium oxide to calcium hydroxide and the carbonation of the hydrated part are carried out immediately after one another under so intensive agitation that the calcium carbonate elements thus created are detached from the surface of the calcium hydroxide. The mixing is preferably carried out in a fluid medium where the amount of gaseous phase is at least 20 parts by volume and the amount of liquid phase is 0.5 to 1 part per one part by volume of the solid matter of the suspension. In the process, the desired end product, PCC, can be prepared in a very short residence time and with a small operational content.
