    Abstract: The invention relates to a setting accelerator for a dry mortar blend, the setting accelerator being in the form of a powder comprising calcium nitrate and having a water content between 0.1% and 20%. The invention furthermore relates to a process for producing such a setting accelerator, wherein either prills and/or granules comprising calcium nitrate and a different nitrate salt are processed forming a powder comprising calcium nitrate and the different nitrate salt and having a water content of higher than 5% and lower than 20%, either an aqueous solution at least comprising dissolved calcium nitrate is spray dried at a temperature between 150° C. and 250° C., forming a powder comprising at least calcium nitrate and having a water content between 0.1% and 20%, the powder serving as the setting accelerator. The invention also relates to a dry mortar blend comprising at least a cement, sand and a setting accelerator according to the invention and to a mortar paste comprising the dry mortar blend according to the invention which is mixed with water.
