Abstract: A method for manufacturing a concrete article is disclosed. The method comprises coating a mould or formwork with a release agent; spraying a mortar onto the mould or formwork, thereby forming a layer of mortar; casting concrete into the mould or formwork and onto the layer of mortar; and allowing the concrete to hydrate and harden in the mould or formwork, whereby a concrete article having a mortar skin layer is provided. The invention also provides concrete articles made by the described methods, and concrete structures which comprise the concrete articles. Concrete articles having the mortar skins can be made to have a relatively uniform outward appearance, even if the concrete cast behind the mortar skins may be different, in composition or appearance. Pigments or colorants and other expensive admixtures can be used in the mortar skin composition to greater visual effect, since the use of the mortar skin is less in overall volume compared to the concrete articles as a whole.

Abstract: This invention relates to apparatus and method for measurement and monitoring of physical properties of materials, such as liquids, and more particularly to acoustic instruments, methods, and systems that automatically measure air content in real-time within liquids, including concrete, mortar, or other hydratable cementitious mix suspensions using resonant electroacoustic transducers that have their radiating surfaces in contact with the liquid.

Abstract: The present invention provides a composition and method for modifying a hydratable cementitious composition such as concrete or mortar using at least three different, distinct carboxylate polymers, even when clay is present in the concrete or mortar that would otherwise diminish dosage efficiency of polycarboxylate polymer used as dispersant. The three polycarboxylate polymers, designated as Polymer I, Polymer II, and Polymer II, are derived from monomer Components A, B, and C wherein Component A is an unsaturated carboxylic acid, Component B is a polyoxyalkylene, and Component C is an unsaturated carboxylate ester. The component molar ratio ranges for A:B:C are different as between Polymers I and II; while a distinct component molar ratio A:B+C is identified for Polymer III. When treated with these three different polycarboxylate polymers, the hydratable cementitious composition is surprisingly enhanced in terms of initial workability and slump retention, especially if clay is present.
Abstract translation: 本发明提供了使用至少三种不同的不同的羧酸盐聚合物改性可水合的水泥质组合物如混凝土或砂浆的组合物和方法，即使当混凝土或砂浆中存在粘土时，否则会降低用作多元羧酸盐聚合物的剂量效率 分散剂。 称为聚合物I，聚合物II和聚合物II的三种聚羧酸酯聚合物衍生自单体组分A，B和C，其中组分A是不饱和羧酸，组分B是聚氧化烯，组分C是不饱和羧酸酯 酯。 A：B：C的组分摩尔比范围在聚合物I和II之间是不同的; 而针对聚合物III鉴定出不同的组分摩尔比A：B + C。 当用这三种不同的聚羧酸酯聚合物处理时，可水合的水泥组合物在初始可加工性和坍落度保留方面出人意料地增强，特别是如果存在粘土。
