The invention described includes a panel made of sheets of expanded polystyrene (EPS) that are held together by tensile connectors on each side of the panel and rebars that extend along the sides of the panel and are bent so that the rebars exert compressive forces urging the sheets of EPS into engagement. The invention also includes a novel concrete for coating the panels after they are arranged to form a structure. The concrete shrinks slightly to form a hard exoskeleton for the structure. A unique foundation for such structure is also enclosed where the panels provide the side forms for a slab of concrete and sand the bottom form.

Composite building material and system for creating structures from such building material

A method of treating concrete pipe (10) is carried out by providing an aqueous lime slurry supply having a lime solids content above 35 % by weight of the slurry. This is mixed within an amount of dispersing agent and may contain an alkali metal hydroxide so that the slurry has a pumpable viscosity. A spray assembly (28) is located within the interior of the pipe. The lime slurry is pumped from this lime slurry supply through the spray assembly (28) so that the lime slurry is applied to the interior surface of the pipe to neutralize acids thereon. Applying the lime spray also provides a protective coating of the lime slurry on the interior surfaces of the pipe.

Method of preventing corrosion in concrete pipe

A knockdown structure and assembly method are provided so as to prevent cracking of the sealant, reinforce the junction between sections, and improve the livability of the structure. A structure's body is assembled by using a mortar-powder mixed adhesive to join together a plurality of sections that are made of foam polystyrene and that constitute the parts of a structure having a predetermined shape. The adhesive is applied to cover at least the places where the sections are joined together with a woven inorganic-fiber mesh sheet. A sealant is applied, made by dispersing inorganic fiber and mortar powder in a plastic-type paint, onto the exterior and interior faces of the structure in a predetermined thickness. Onto the sealant of the exterior of the structure is applied, on the exterior of the structure, a paint that is water repellant and can screen out ultraviolet light, and applying, over the sealant of the interior of the structure, a clayey paint made of natural substances.

Knockdown structure and methods of assembling same

A knock-down house that avoids substrate cracking, being capable of strengthening the junction of pieces, and that enhances livability; and a method of building the same. There is provided a method of building a knock-down house, comprising the steps of coupling multiple pieces of polystyrene foam resulting from division of given house configuration together with an adhesive having mortar powder mixed therein to thereby assemble a house main body; bonding mesh sheets made of inorganic fiber at least so as to cover piece coupling parts; applying a given thickness of substrate composed of inorganic fiber and mortar powder both dispersed in a resin coating material onto exterior surfaces and interior surfaces of the house main body; and applying a water-repellent ultraviolet-shielding exterior paint onto the exterior-surface substrate while applying a clayey paint derived from natural matter onto the interior-surface substrate.

Knock-down house and method of building the same

An hydraulically set oil-permeable cement body is provided in the form of a stand-alone block or briquette for preserving cooking oil during deep fat frying, said body. It has substantially no free water or having a low free water content for resisting damage on immersion in cooking oil and initial heating and is enclosed in packaging that resists ingress of water or water vapor The block or briquette consists of >50 wt % of a mixture of milled white OPC clinker and white OPC, optionally silica 1-2 wt % and/or titania (TiO 2 ) 1-2 wt % and optionally further ingredients selected from calcium silicate, magnesium silicate, aluminum silicate, natural feldspars, natural sodium zeolites, natural calcium zeolites, synthetic sodium zeolites, synthetic calcium zeolites, wollastonite, calcium hydroxide, clays, pillared clays, activated clays/earths, talcs/kaolinite, amphiboles, granite porphyry, rhyolite, agalmatolite, porphyry, attapulgite and diatomaceous earth. It has the properties that calcium and magnesium substantially do not leach into the oil and that it is porous so that oil can diffuse into it and contaminants can be deposited on and within it.

Hydraulically set cement body for preservation of organic liquids

A dry mortar mix based on an inorganic bonding agent and optionally additives, plastics, fibres, and other conventional concrete additives is proposed especially to protect concrete structures and/or to eliminate surface damage to such structures In addition to the inorganic bonding agent, the dry mortar mix contains a granular additive to increase alkalinity, this having a reaction speed that is a considerably lower than that of the granular bonding agent This "reserve alkalinity" serves to counteract the diffusion of CO 2 and SO 2 from the air into the concrete, and the damage to the concrete that is attendant on such diffusion
