High-performance mixer for advanced cement-based composites

一台高性能搅拌机被用来支持对先进水泥基复合材料的本构响应和用这些材料建造的结构元件的结构响应的研究。尤其是，它将支持受控生产的材料类别，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)，这些材料的特征是致密的胶凝基质和非常高体积分数的短钢纤维。阿尔伯塔大学正在进行的一系列实验项目强调先进水泥基复合材料在结构上的应用，使用创新的结构系统，以及现有混凝土结构的修复。他说，拟议的设备能够现场生产专门针对所调查的应用所需的材料特性(例如，机械响应、耐久性)的混凝土混合料。

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.
