自密实混凝土（SCC）比传统混凝土具有生态和经济优势，特别是对于预制混凝土行业。除了适当的混合物配比和制造程序之外，SCC 的机械特性及其对构件结构行为的影响对于确保有效应用特别重要。有许多新鲜和硬化 SCC 的材料模型可用，但其结构行为尚未得到充分描述。尽管先前的研究表明 SCC 的特性不会影响构件的弯曲能力，但 SCC 对粘结强度和剪切能力的影响尚不完全清楚。因此，对 SCC 构件的粘结强度和剪切能力进行了测试，并在本研究中进行了详细介绍。目的是收集 SCC 构件结构行为的缺失信息，并实现经济可靠的预应力混凝土梁设计。
Self-consolidating concrete (SCC) offers ecological and economic advantages over conventional concrete, especially for the precast concrete industry. Besides proper mixture proportioning and manufacturing procedures, the mechanical characteristics of SCC and its effects on a member's structural behavior are of particular interest to ensure efficient application. Numerous material models for fresh and hardened SCC are available, but its structural behavior has not been fully described. Although prior studies have shown that characteristics of SCC do not affect a member's bending capacity, SCC's influence on bond strength and shear capacity is not completely understood. Therefore, tests on bond strength and shear capacity of members made with SCC have been performed and are detailed in this research. The aim was to collect missing information on the structural behavior of members made from SCC and to allow an economical and reliable design of prestressed concrete beams.
