Method for producing nanosized calcium hydroxide crystals or particles, according to which method the calcium oxide-bearing initial material is brought into contact with carbon dioxide in the aqueous phase. Calcium carbonate crystals or particles are produced in a mixture, the pH of which is below 7. Using the present invention, it is possible to combine the two stages of producing CaCO3 particles...

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...

Wave Energy Converter (WEC) consisting of rows of pipes with open ends plunged into the sea wherein the water level rises and falls with the waves thereby- creating a pressure and suction airflow in the pipes. The pipes communicate with integral pressure and suction main channels through pressure and suction valves. A PTO unit is placed between the main channels and exploits both the air pressure ...
