摘要： Cement compositions comprising a modified styrenic block copolymers and methods for making/using the same are disclosed. The modified styrenic block copolymer has at least one monoalkenyl arene polymer block A, at least one conjugated diene polymer block B, and at least an epoxy functional group or derivative thereof. The modified styrenic block copolymer has a degree of epoxidation of up to 10-90%. The cement composition can be used in subterranean applications, as well as in building and construction materials. The modified styrenic block copolymers swell upon contact water or other aqueous fluids to seal cracks in the cement.

摘要： The present invention provides dry mix compositions for cement-based tile adhesives having both improved open time and slip resistance comprising one or more gel-like crosslinked cellulose ethers containing polyether groups, preferably, a mixed cellulose ether having polyoxypropylene dioxyethylene ether crosslinks. The gel-like water-soluble crosslinked cellulose ethers containing polyether groups of the present invention are formed from low to medium viscosity cellulose ethers and contain polyether groups having from 2 to 15, or, preferably, 13 or fewer oxyalkylene groups, or, preferably, 7 or more oxyalkylene groups. The present invention also provides methods of using the dry mixes in cement-based tile adhesives.

摘要： A concrete slab on ground system includes a first slab portion and a second slab portion. The first slab portion is disposed on a ground substrate and includes geopolymer cement (GC) concrete. The second slab portion is disposed on the first slab portion and consists of Portland cement (PC) concrete. The first slab portion may be mixed in-situ and left in an unfinished state such that only the top or exposed surface of the second slab portion need be finished.

摘要： A cement slurry including graphene, a cementitious material, and water; the graphene comprises bioderived renewable graphene (BRG). The cement slurry can comprise from about 0.01 to about 20, from about 0.1 to about 15, from about 0.5 to about 5 percent graphene by weight of cementitious material (% graphene bwoc). The cement slurry can have enhanced stability, as evidenced by a uniform density of the slurry and a reduction in free fluid, according to API 10B-2, relative to a same cement slurry absent the graphene.

摘要： Pumpable slurry compositions comprising at least one aluminosilicate additive and optional pozzolanic cement additives and methods for improving development of compressive strengths in the pumpable cement slurry compositions are disclosed herein. The methods utilize one or more pumpable cement slurry compositions comprising at least one cement component, water, at least one first aluminosilicate additive, at least one optional second aluminosilicate additive, and one or more optional pozzolanic additives, wherein the at least one first aluminosilicate additive has an amorphous phase of greater than about 50% and a weight ratio of silica oxide to aluminum oxide of about 1.0 to about 2.5, and the at least one optional second aluminosilicate additive has a weight ratio of silica oxide to aluminum oxide of about 1.7 to about 3.3.

摘要： A concrete mixture is forced through a nozzle by an extruder. An applicator has: a body adapted for vertical movement; a primary arm mounted to the body for movement about a vertical axis, the arm being elongate, having ends, having a vertical axis adjacent one end and having a counterweight adjacent the other end; a secondary arm defining a vertical axis, extending from the vertical axis defined by the primary arm and configured for movement about said vertical axis; a tertiary arm mounted for movement along the secondary arm vertical axis; a rotator carried by the tertiary arm and which carries the nozzle and rotates the nozzle about a vertical axis; a primary rotation mechanism for rotating the primary arm about the primary arm axis; an actuator providing for movement of the secondary arm about the vertical axis; and an elevation mechanism providing for said tertiary arm vertical movement.

摘要： 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.
