New inorganic thickener for drymix mortars
An attapulgite (needle-shaped magnesium alumino silicate) named Acti-Gel 208 has been developed by Active Minerals Company LLC (USA). Compared with normal attapulgites it is easier to (re-)disperse and gives the final rheology immediately after mixing the dry-mix mortar with water.
More detailed information and samples are available from the agency which represents Active Minerals in Europe:

New preservative for concrete admixtures
This month the manufacturer of biocides Schülke & Mayr GmbH brings a new preservative named GROTAN® TK 3 PLUS to the market, which was specially developed for use in concrete admixtures. It is a broad-spectrum bactericide and fungicide and it's efficiency remains even at high temperatures up to 60°C (140°F). Furthermore it is usable between pH 3 and 11 and that covers the whole range of waterborne concrete admixtures.
