    Abstract: A concrete-forming composition for producing a concrete article including: (a) at least one internal curing agent including a water-insoluble crosslinked cellulose ether wherein the water-insoluble crosslinked cellulose ether has a higher water adsorption capacity compared to typically used superabsorbent polymers and wherein the water- insoluble crosslinked cellulose ether can be successfully and efficiently used as a water- insoluble crosslinked cellulose either internal curing agent in concrete-forming compositions; and (b) a cementitious material; a process for making the above concrete- forming composition; and a concrete article made from the above concrete-forming composition with the objective of reducing autogenous shrinkage and crack formation in the resulting concrete article made from the above concrete-forming composition.

    Abstract: The present invention provides cementitious tile adhesives comprising ordinary Portland cement, sand or another inorganic filler, and from 0.12 to 0.6 wt.% of total solids of one or more polyether group containing crosslinked cellulose ethers. The present invention also provides methods of making the polyether group containing crosslinked cellulose ethers comprising crosslinking a cellulose ether at 90 °C or less, in an inert atmosphere, e.g. nitrogen, in the presence of a polyether group containing crosslinking agent and in the presence of alkali; the process may comprise part of a stepwise addition process of making of a cellulose ether itself in which the crosslinking of the cellulose ethers precedes at least one addition of alkyl halide or alkylene oxide to form, respectively, alkyl or hydroxyalkyl groups on the cellulose.

    Abstract: The present invention provides dry mix compositions for cement-based tile adhesives having both improved open time and slip resistance comprising one or more gel-like crosslinked cellulose ethers containing polyether groups, preferably, a mixed cellulose ether having polyoxypropylene dioxyethylene ether crosslinks. The gel-like water-soluble crosslinked cellulose ethers containing polyether groups of the present invention are formed from low to medium viscosity cellulose ethers and contain polyether groups having from 2 to 15, or, preferably, 13 or fewer oxyalkylene groups, or, preferably, 7 or more oxyalkylene groups. The present invention also provides methods of using the dry mixes in cement-based tile adhesives.
