摘要:
A wallboard sheet includes a core having opposing first and second major surfaces, at least one face layer on at least one of the first and second major surfaces of the core, and wherein the core includes aerated concrete. The provision of aerated concrete for the core provides many key advantages over conventional wallboard sheets, such as gypsum wallboard, for example. The at least one face layer may include first and second face layers on respective first and second major surfaces of the core. The one or more face layers may include paper. The core may have a generally rectangular shape defining a pair of opposing side edges and a pair of opposing end edges. The first major surface may have beveled portions adjacent respective opposing side edges in some embodiments. The at least one face layer may extend around the opposing side edges. In addition, the opposing end edges of the core may be exposed.

摘要:
There are disclosed an artificial marble containing pellet-shaped transparent chips, obtained by coating the outer surface of an internal transparent resin layer with a resin layer containing a filler having a high specific gravity using co-extrusion, and a process for preparing the same. The artificial marble using the transparent chips as coloring chips, thus not causing the occurrence of layer separation of the transparent chips, which conventionally occurred in an artificial marble using transparent chips made of a single component, being distinguished from a conventional artificial marble made of combination of the single-colored chips, and expressing a pattern similar to a natural granite.
摘要:
A lightweight cementitious composition comprising 22 to 90 volume percent of a cement composition and from 10 to 78 volume percent of particles having an average particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.03 g/cc to 0.64 g/cc, an aspect ratio of from 1 to 3, where after the lightweight cementitious composition is set it has a compressive strength of at least 1700 psi as tested according to ASTM C39. The cementitious composition can be used to make concrete masonry units, construction panels, road beds, and other articles can be included as a layer on wall panels and floor panels and can be used in insulated concrete forms. Aspects of the lightweight cementitious composition can be used to make lightweight structural units such as those shown in Figure 7 with lightweight concrete 550 in relation to embedded metal studs 514.
摘要:
A vertical shear wall system including vertical metal framing members, for example, C-joists, U-joists, open web joists, or other metal frame systems that support a reinforced, lightweight, dimensionally stable SCP panel. The shear wall system is non-combustible, water durable, mold and rot resistant, termite resistant and is capable of resisting shear loads equal to or exceeding shear loads provided by plywood or oriented strand board panels. The panels employ one or more layers of a continuous phase resulting from the curing of an aqueous mixture of inorganic binder, for example, calcium sulfate alpha hemihydrate, hydraulic cement, an active pozzolan and lime. The continuous phase is reinforced with glass fibers and contains lightweight filler particles, for example, ceramic microspheres.
