摘要: A composition of a cement additive material to improve durability of cementitious structures, was disclosed. The cement additive composition includes an admixture of one or more of divalent magnesium metal silicates with capacity to act as a latent hydraulic binder in said composition activated by a hydration process under aqueous conditions, and in particular the divalent metal silicate is magnesium-dominated silicate, preferably comprising mineral groups of olivines, orthopyroxenes, amphiboles, talc and serpentines or mixtures thereof. The composition also includes chloride ions or brine. Applications of the compositions are also disclosed, in particular to utilize a property of hydration as a major trigger for the latent hydraulic reaction of magnesium silicates, particularly for said olivines, when exposed to water and brines, in order to obtain a cementitious material becoming self healing.

摘要: A cost-effective and practical antimicrobial glaze system and glazing process is disclosed herein. The antimicrobial glaze/enamel may comprise at least two layers: a base layer and a top layer. The base layer may contain a typical or normal glaze widely used in sanitary ware, having a low level of zinc oxide. The base layer glaze may be directly sprayed on the clay body surface. A thin top glaze layer is sprayed on top of the base glaze layer and the top layer may contain a high level of zinc oxide.

摘要: It has been unexpectedly discovered that the addition of a non-spec natural 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. 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, by utilizing natural pozzolans. 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.

摘要: A method of producing high-strength cementitious product from raw fly ash by mixing the raw fly ash with a lithium compound, whereby milling of the raw fly ash to achieve requisite strength is unnecessary. It has now been found that by adding as little as 0.1% of lithium chloride to raw untreated Class C fly ash, one can achieve improved seven-day and twenty-eight-day compressive strength. At the very least, raw lithium treated Class C fly ash may be used at lower total cementitious content per yard of concrete as opposed to Ordinary Portland Cement (OPC) for improved compressive strength.
