A cement admixture containing one kind or two or more kinds of non-hydraulic compound(s) selected from γ-2CaO.Math.SiO.sub.2, 3CaO.Math.2SiO.sub.2, α-CaO.Math.SiO.sub.2, and calcium magnesium silicate, wherein the non-hydraulic compound contains Li, and the content rate of the Li is 0.001 to 1.0% by mass in terms of oxide. Such admixtures may contain, as chemical components, 0.001 to 1.0 parts by mass of Li.sub.2O, 45 to 70 parts by mass of CaO, 30 to 55 parts by mass of SiO.sub.2, and 0 to 10 parts by mass of Al.sub.2O.sub.3 in 100 parts by mass of the cement admixture.

The invention relates to a composite formulation comprising a specific mediator additive component (A) of relatively high molecular weight, a filler component (B) and a binder component (C). The composite formulation can be cured to a composite which is especially suitable for the production of moldings.

The present invention provides dry mixes for skim coat mortars having improved pot life and workability while reducing cellulose ether dosage comprising a white cement, one or more fillers having a sieve average particle size of from 15 to 60 microns, from 0.25 to 0.5 wt. % of one or more gel-like crosslinked cellulose ethers containing polyether groups, preferably, a mixed cellulose ether having polyoxypropylene dioxyethylene ether crosslinks, and from 1 to 2.5 wt. % of one or more polymer redispersible powders (RDP). At least one gel-like crosslinked cellulose ether has a crossover point as measured by oscillation rheometry, at which storage modulus (G′) and loss modulus (G″) intersect and are identical, of 1.0ω or less. The present invention also provides methods of using the dry mixes.

Disclosed is a method to produce composite materials, which contain customized mixes of nano- and/or micro-particles with tailored electromagnetic spectral properties, structural elements based thereon, in particular layers, but also bulk materials including inhomogeneous bulk materials. In some embodiments the IR-reflectivity is enhanced predominantly independently of reflectivity for visible wavelength. The enhanced IR-reflectivity is achieved by combining spectral properties from a plurality of nano- and/or micro-particles of distinct size distribution, shape distribution, chemical composition, crystal structure, and crystallinity distribution. This enables to approximate desired target spectra better than know solutions, which comprise only a single type of particles and/or an uncontrolled natural size distribution. Furthermore disclosed are methods of manufacturing such materials, including ceramics, clay, and concrete, as well as applications related to design and construction of buildings or other confined spaces.
