    摘要: Glass-fiber-reinforced concrete compositions that may be sprayed, and methods of preparing and applying such compositions. Such compositions may include cement, reinforcing glass fibers randomly oriented and homogenously distributed throughout the concrete composition, and a particle packing aggregate. At least a portion of the particle packing aggregate may be rounded rather than crushed and include a first aggregate portion having a first particle size and a second aggregate portion having a second particle size that is smaller than the first particle size so that the aggregate is capable of particle packing. The uncured compositions can be delivered through a spray nozzle with the glass fibers already mixed into the composition. The compositions can provide uniform, non-directional strength characteristics, e.g., modulus of rupture of at least 16 MPa and a limit of proportionality of at least 7 MPa with a glass-fiber content of no more than 4% by weight.

    摘要: A ceramic precursor batch composition comprising inorganic ceramic-forming ingredients, a binder, an aqueous solvent and a heteroatom polyol agent. The heteroatom polyol agent can be represented by X(R) where X is at least one of S, N, and P, and R is at least two of CH3, CH2CH2OH, CH2CH2CH2OH, CH2(CHOH)CH3, C(CH2OH)1-3, CH2OH, CH(CH2OH)CHOH, C(O)(CHOH)1-4CH2OH, and CH2CH2CH2OCH3. The presence of the heteroatom polyol agent provides a composition with a lower viscosity and/or a greater batch stiffening temperature (Tonset) allowing for increased rates of extrusion. Methods for producing a ceramic honeycomb body using this ceramic precursor batch composition are also provided.
