A composition comprising at least one binder coated with at least one metallate additive according to formula 1: (RO).sub.m-M-(O.sub.a˜X.sub.b˜R′.sub.c˜Y.sub.d).sub.n (formula 1), wherein M is one of titanium and zirconium. The composition is particularly useful in producing treated binders and construction materials, wherein the resulting treated binders and construction materials have advantageous properties, such as increased strength. Also disclosed are methods of preparing the inventive composition, treated binders and construction materials.

A cement grout material is provided, which does not freeze even in an environment where the ambient temperature can be −5° C. or below, and which does not require fuel or large-scaled equipment for maintaining curing temperature. Lithium nitrite is added to a cement grout material that contains cement, water and an admixture. By setting the weight ratio of the lithium nitrite to the cement to a value from 3 to 10% by weight, freezing of the grout material is able to be prevented even in an installation environment where the ambient temperature can be −5° C. during the initial stage of installation. By setting the weight ratio of the lithium nitrite to the cement to a value from 4.5 to 8% by weight, freezing of the grout material is able to be prevented even in an installation environment where the ambient temperature can be −10° C. during the initial stage of installation.

A method for controlling the volume expansion of a hydraulically setting composition including steel making slag, the method including a step of adding a silica source to the composition. Furthermore, hydraulically setting compositions obtained by such methods and their uses.

It is disclosed the use of amorphous silica reagent produced from serpentine as pozzolane additive material, and more particularly a concrete mixture, such as high performance and ultra-high performance concrete, comprising a hydraulic binder; sand; aggregates, chemical admixture, mineral admixture as silica fume and an amorphous silica reagent (AmSR), wherein the AmSR is admixed for example with General Use Portland Cement and provides synergistic effect when combined with silica fume.

A mixture along with methods of preparing, uses and/or products made from the mixture and methods of preparing products made from the same. Where the mixture contains 0.5% to 10% by weight of one or more superabsorbent polymers and 90% to 99.5% by weight of one or more protective-colloid-stabilized polymers based on one or more ethylenically unsaturated monomers and optionally one or more additives. Where the percentages by weight are based on the dry weight of the mixture and wherein no mineral binder is present within the mixture.

Described herein are compositions comprising hemp, minerals, and water. Such compositions may be used in construction, building materials, insulation, etc. Such compositions may be sprayed, poured, cast, molded, etc.

The present invention relates to a construction material composition comprising at least one non-ionic copolymer and the use of said construction material composition. Further, the present invention relates to a non-ionic copolymer and the use thereof for modifying robustness against clay deviations.

The invention relates to radiation-treated reinforcement fibers, reinforced asphalt and portland cement concrete, and grout, methods for producing the same and application for their use. The radiation treatment includes exposing reinforcement fibers to electromagnetic energy, e.g., gamma rays, and/or electron-beam (E-beam) radiation. As a result of the treatment, the radiation-treated reinforcement fibers have a modified or deformed surface, e.g., an abraded and/or porous surface, as compared to reinforcement fibers without a radiation treatment.

Novel cement, concrete, mortar and grout embodiments for construction. The materials are produced through SCM and quicklime aqueous cement formation reactions. A novel cement is also presented that can be used to form improved concrete, mortar and grout placements. Several novel concrete embodiments are presented that can be used with any aggregate, and for any construction application; including saltwater marine placements.

Compositions and a method for making self consolidating grouts containing fly ash, ground granulated blast slag, and lime are described. No polymeric admixtures are utilized, and the 28 day cure strength of the cured gouts exceeds the minimum ASTM standards. The uncured grout exhibits slump flows between 24 and 30″ without visible segregation of the components.
