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.

一种高性能搅拌机被提议用于支持先进水泥基复合材料的本构响应研究，以及用这些材料建造的结构元件的结构响应研究。特别是，它将支持材料类别的受控生产，包括：轻质水泥泡沫，“传统”混凝土，纤维增强混凝土，和超高性能混凝土（UHPC），其特征在于具有非常高体积分数的短钢纤维的致密水泥基基质。 阿尔伯塔大学正在进行的实验项目强调先进水泥基复合材料在新建筑中的结构应用，采用创新的结构系统，以及现有混凝土结构的修复。 所提出的设备使得能够现场生产专门针对材料特性（例如，机械响应、耐久性）。
