Disclosed is a composite white pigment having mixed together white pigments having different colorimeter values from each other by comprising substrates having various sizes and/or TiO2 having various thicknesses. The composite white pigment, according to the present invention, comprises: a first white pigment comprising a substrate and a white metal oxide layer formed on the substrate; and a second white pigment comprising a substrate and a white metal oxide layer formed on the substrate, and having a different colorimeter value from that of the first white pigment.

Composite roofing structures can include mineral fiber roof cover boards with high concentration of mineral wool or mineral wool and perlite. The roofing structure may include: a roof cover board including a dried base mat including: 8-25% mineral wool, 40-65% perlite, 9-15% binder, 9-15% cellulosic fiber, and 0.25-2% sizing agent, all % by weight; an insulation layer; and a roofing membrane. The roof cover board is over the insulation layer, the roofing membrane is over the roof cover board. The roof cover board is attached to the insulation layer. The roofing membrane is attached to the roof cover board. Alternatively dried base mat may include: 30-70% mineral wool, 10-50% perlite, 5-15% binder, 2-20% cellulosic fiber, and 0.25-2% sizing agent. Alternatively the dried base mat may include: 60-90% mineral wool, 0-10% fiber, 0-10% perlite, 4-10% binder, 0-5% gypsum, and 0.25-2% sizing agent.

A repair compound for use in all applications and particularly well-suited for large hole repair. The repair compound includes a latex resin, a thickener, fibers, and a filler material. In some embodiments, the repair compound is configured to exhibit pseudoplastic-type behavior. In some embodiments, the repair compound has a density of not greater than 4.0 lbs/gal. In some embodiments, the repair compound includes hydrophobic and hydrophilic fibers of different morphologies. In some embodiments, the repair compound includes HASE-type thickeners. In some embodiments, the repair compound includes a bimodal distribution of hollow glass microspheres from two different strength/size curves.

The invention relates to a sleeper for the track superstructure, which is manufactured in one piece from a plastic material, with the sleeper having an elongated base shape with two end sections, which are connected by a middle section of the sleeper and held at a distance and on their upper side in each case one contact surface is provided for in each case one rail to be supported on the respective end section with a reinforcement extending in the longitudinal direction of the sleeper being embedded into the middle section. In order to design such a plastic sleeper such that it has optimised strength and can be reliably manufactured even using cost-effective plastic/sand mixtures having a high proportion of sand, the invention proposes that the reinforcement extends over the length of the middle section, that the reinforcement is in each case anchored in the respective end section an edge region of the end sections assigned to the middle section and in that the reinforcement is wholly or partially arranged in the upper quarter of the height of the sleeper.
