硅灰(又称微硅粉)作为硅铁工业的副产品,已在建筑行业和陶瓷耐火材料行业等领域得到广泛应用,但在水泥混凝土生产中,硅灰的使用仅限于高强、高性能混凝土的配制和生产,而且对硅灰的自身质量水平要求很高;本文通过混凝土试配试验,对质量不太高的原态硅灰在普通中低强度等级混凝土中的应用进行初步探讨。 As a by-product of the ferrosilicon industry, silica fume (also known as micro-silica fume) has been widely used in the construction industry and ceramic refractory industry. However, the use of silica fume is limited to high-strength and high-performance concrete Preparation and production of silica fume, but also has high requirements on the quality of silica fume itself. In this paper, through the concrete trial, the application of low-quality raw silica fume in ordinary medium-low strength concrete is discussed.
