High-performance mixer for advanced cement-based composites

为了研究先进水泥基复合材料的本构响应以及用这些材料建造的结构单元的结构响应，提出了一种高性能搅拌机。特别是，它将支持材料类别的受控生产，包括：轻质胶凝泡沫，“传统”混凝土，纤维增强混凝土和超高性能混凝土（UHPC），其特点是密集的胶凝基质具有非常高的短钢纤维体积分数。阿尔伯塔大学正在进行的实验项目强调使用创新结构系统将先进的水泥基复合材料用于新建筑的结构应用，以及对现有混凝土结构的修复。提议的设备能够现场生产混凝土混合物，这些混凝土混合物是根据所调查应用所需的材料特性（例如，机械响应，耐久性）专门定制的。

A high-performance mixer is proposed to support research on the constitutive response of advanced cement-based composites, and the structural-response of structural elements built with these materials.  In particular, it will support the controlled production of material classes including: lightweight cementitious foams, "traditional" concrete, fiber reinforced concrete, and Ultra-High Performance Concretes (UHPC) that are characterized by a dense cementitious matrix with very high volume fraction of short steel fibers.     Experimental programs in progress at the University of Alberta emphasize the structural application of advanced cement-based composites for new construction using innovative structural systems, and the rehabilitation of existing concrete structures.    The proposed equipment enables on-site production of concrete mixes that are specially tailored to the material properties (e.g., mechnical response, durability) that are required for the application investigated.
