20090025614 | High strength magnesium slag brick and method of producing the same - This invention discloses a high strength magnesium slag brick and a method of producing the same. The high strength magnesium slag brick is composed of 60 to 80 percent by weight of furnace slag from the reduction process of a magnesium production, 15 to 25 percent by weight of crushed stones and/or pebbles, and 1 to 15 percent by weight of gypsum and/or lime. And the amount of water added to the composition is equivalent to 10 to 40 percent of the total weight of raw materials. The method includes dispensing of raw materials, adding of water, mingling, leaving it piled-up, pressing and molding, steam-bathing and drying to obtain the finished product. Gypsum, one of the raw materials of the slag brick, can be produced from the waste gas generated from the magnesium production process. And, the coal cinder or coal ash generated from the burning of coal in the magnesium production process, can also be used as one of the raw materials of the slag brick. This invention uses massive volume of furnace slag from the reduction process of a magnesium production, and together with aforesaid raw materials, to produce construction bricks, easing the environmental pollution problem on one hand, and introducing a new environmental building material on the other hand. The method of producing high strength magnesium slag brick of this invention is simple and is easy to manage. The raw materials are readily available. The production cycle is shorter than conventional processes. The strength of the magnesium slag brick meets the standard of construction brick. And most of all, it is very environmental friendly and economical. | 01-29-2009 |

20110259246 | HIGH EARLY STRENGTH POZZOLAN CEMENT BLENDS - A high early strength blended cement composition includes larger sized fly ash and/or natural pozzolan particles blended with smaller sized hydraulic cement particles containing tricalcium silicate and/or dicalcium silicate (e.g., Portland cement and/or ground granulated blast furnace slag). Excess calcium released from the hydraulic cement particles when mixed with water forms calcium hydroxide available for reaction with the fly ash and/or natural pozzolan. The fineness of the hydraulic cement particles is substantially greater than the fineness of the fly ash and/or natural pozzolan particles (e.g., about 1.25 to about 50 times greater). Reducing or eliminating coarse hydraulic cement particles that cannot fully hydrate but include unreacted cores reduces or eliminates wasted cement normally found in concrete. Replacing some or all of the coarse cement particles with coarse pozzolan particles provides a blended cement composition having significantly lower water demand compared to the hydraulic cement fraction by itself. | 10-27-2011 |

20150144030 | PARTICLE PACKED CEMENT-SCM BLENDS - Cement-SCM blends employ particle packing principles to increase particle packing density and reduce interstitial spacing between the cement and SCM particles. Particle packing reduces the amount of water required to obtain a cement paste having a desired flow, lowers the water-cementitious material ratio (w/cm), and increases early and long-term strengths. This may be accomplished by providing a hydraulic cement fraction having a narrow PSD and at least one SCM fraction having a mean particle size that differs from the mean particle size of the narrow PSD cement by a multiple of 3.0 or more to yield a cement-SCM blend having a particle packing density of at least 57.0%. | 05-28-2015 |

20150376061 | POZZOLANIC COMPOSITIONS CONTAINING FLY ASH AND REMEDIATION AGENTS FOR USE IN CEMENTITIOUS MATERIALS - It has been unexpectedly discovered that the addition of a natural or other pozzolan to non-spec fly ash significantly improves the properties of the non-spec fly ash to the extent it can be certified under ASTM C618 and AASHTO 295, as either a Class F or Class C fly ash. The natural pozzolan may be a volcanic ejecta, such as pumice or perlite. Other pozzolans may also be used for this beneficiation process. Many pozzolans are experimentally tested and may be used to beneficiate non-spec fly ash into certifiable Class F fly ash. Additionally, this disclosure provides a method of converting a Class C fly ash to a more valuable Class F fly ash. This discovery will extend diminishing Class F fly ash supplies and turn non-spec fly ash waste streams into valuable, certified fly ash pozzolan which will protect and enhance concrete, mortars and grouts. | 12-31-2015 |
20160068437 | Biomass-Derived Grinding Aids - Compositions and methods for increasing grinding efficiency of cement, cement clinker, raw materials for cement, and other inorganic particles.

20160145153 | GREEN BRICK AND METHOD FOR PRODUCING THE SAME - A green brick includes a brick body that is further consisted of a lubrication adhesive and an aggregate. The lubrication adhesive and the aggregate are mixed and then applied by a specific pressure so as to form the brick body. The lubrication adhesive is consisted of an activating solution and a binder. The binder is blast furnace slag, agricultural waste ashes, or a combination of the blast furnace slag and the agricultural waste ashes. Thus, the blast furnace slag and the agricultural waste ashes that are originally to be discarded are now recycled to form the green brick, such that the environmental pollution caused thereby can be reduced to a minimum. | 05-26-2016 |
