自密实混凝土是一种具有较高流动性能的混凝土,它能仅依靠重力填充模板,因此自密实混凝土有降低工人劳动强度、减少施工噪音等优点,近年来自密实混凝土虽逐渐大量使用,但多是定性测试其工作性能,而其流变规律尚不完善,为了解自密实混凝土流变特性,应从自密实混凝土流变模型及流变参数测试入手。
Self-compacting concrete is a kind of concrete with high flowability. It can only rely on gravity to fill the formwork. Therefore, self-compacting concrete has the advantages of reducing labor intensity and reducing construction noise. In recent years, self-compacting concrete has been gradually used in large quantities, but mostly Qualitative test of its performance, and its rheological rules are not perfect, in order to understand the rheological properties of self-compacting concrete, self-compacting concrete rheological model and rheological parameter testing should start.
