The invention comprises a method of forming a slab on grade. The method comprises placing a first layer of insulating material horizontally on the ground and placing plastic concrete for a slab on grade on the first layer of insulating material. The plastic concrete is then formed into a desired shape having a top and sides. A second layer of insulating material is placed on the top of the plastic concrete and the first and second layers of insulating material are left in place until the concrete is at least partially cured. The second layer of insulating material is then removed. The product made by the method is also disclosed. A slab on grade is also disclosed.

Embodiments of a system and a method for manufacturing a cementitious panel can be used to produce a cementitious panel having a multi-layer air/water barrier membrane assembly. The layers of the membrane can be built up via a series of applicator stations applying a fluid composition using roll coating, for example. Between applicator stations the applied layer of fluid composition can be subjected to drying conditions via infrared heating. To help protect from the deleterious effects of infrared heating, the cementitious panel can be conveyed through a cooling tunnel after each drying section.

A tile backer board has 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide, 14 wt % of 18 wt % of a magnesium chloride dissolved in water; 0.1 wt % to 10 wt % of a stabilizing material with a phosphorus-containing compound, reacting into an amorphous phase cementitious material. The phosphorus-containing compound is a phosphorous acid (A) or a phosphoric acid (B). 0.1 wt % to 30 wt % of an aggregate is added and then a reinforcing component is mixed in or the cement is poured onto the reinforcing component forming a tile backer board.

A process to make a tile backer board includes using a stabilizing material with a phosphorus-containing compound, reacting magnesium containing starting materials into an amorphous phase cementitious material, and adding 0.1 wt % to 30 wt % of an aggregate and a reinforcing component by mixing in or pouring over the reinforcing component and allowing the amorphous phase cementitious material to cure into a tile backer board.

A process to make a cementitious material includes blending 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide based on a final total weight of the cementitious material with 14 wt % to 18 wt % of a magnesium chloride dissolved in water and reacting to form a liquid suspension, mixing from 2 to 10 minutes, adding a phosphorus-containing material, and allowing the liquid suspension to react into an amorphous phase cementitious material. A portion of the amorphous phase cementitious material grows a plurality of crystals. The plurality of crystals is encapsulated by the amorphous phase cementitious material forming a nano-molecular veneer.

A contact layer used in waterproofing and roofing applications. The contact layer includes a solid filler component F and a thermoplastic polymer component P. Also directed to a method for producing the contact layer, to a method for binding two substrates to each other, to a method for waterproofing a substrate, to a waterproofed structure, to a method for sealing a surface against water penetration, to a sealed construction for sealing a substrate against water penetration and to use of the contact layer as waterproofing membrane.

An artificial stone building tile and method. Disclosed is an artificial stone building tile and a method of making the building tile. The building tile has a low density and significant flexibility, and is nailable without cracking. It is made by layers of cement formulations separated by layers of metal mesh. Color batches of cement are prepared and placed in the bottom of a mold, with the color batches becoming the visible face of the building tile.

Environmentally responsible insulating construction blocks and structures constructed primarily of recycled materials are disclosed. The environmentally friendly construction blocks and structures comprise shredded rubber tire pieces coated with silica fume, slag cement and cement, which are then mixed with water and formed in a mold. A layer of grout or a fireproof material may be disposed on one side of the environmentally responsible insulating construction block. The environmentally responsible insulating construction blocks provide high insulation as well as strength for applications such as green roofing, wall construction and green roofing decks. Environmentally friendly structures can be built by pouring the coated shredded rubber tire pieces into molds to form walls, and then to pour a layer of the coated shredded rubber tire pieces as a roof deck, thereby creating a self-supporting structure in a monolithic pour.

Cementitious binder compositions for cementitious products including a hydraulic cement-based reactive powder blend, an inorganic flow control agent, and a metal-based dimensional movement stabilizing agent including at least one member of the group of lithium salt and lithium base, and methods for making the cementitious binder compositions.

A support structure, including an excavation and a plurality of irregularly shaped foamed glass bodies at least partially filing the excavation. Each respective irregularly shaped foamed glass body has an aspect ratio of about 1:1.7 and a diameter of about 1 inch. The irregularly shaped foamed glass bodies intersect to define stacking angles of at least about 35 degrees. Under compression, the irregularly shaped foamed glass bodies crush and break up before slip failure occurs such that the roadbed has a crushing failure mode.
