Developement or improvement of dry mix mortar products up to certification.

OPC [Ordinary Portland Cement], OPC clinker, HAC [High Alumina Cement], phosphate cement,
liquid potassium silicate or alternative raw materials are used as binder. Quartzsand or limestone
powder are aggregate and with the right additives you get your dry mix mortar product.
New options arise from an accurate controlled hydratation, silification, acid-base reaction or by
use of crystaline phases, being ignored up to now. A new approach should be tested concerning
Ultra High Performance Concrete [UHPC] and also a new special tile adhesive for high performance
non-porous tiles with water absorption < 0,2 % instead of usual adhesive for tiles with < 3% w.a..

Liquid potassium silicate, white and grey OPC were used for different developements. The silicate
products are twice shrinkage reduced with 10 or 40 min. time of workability. They can be used for
natural stone bonding or high resistant applications on a dry surface, being an option to epoxy products.
Further developments are a white or jet black Cararra Joint Filler, an Ultra High Resistant Joint Filler
for drinking water catch basins and passed TOC-conc..- Really new is a cementitious drainage-grout
without soluble Ca-Ions with a MAP 50% of a conventional joint filler.
