在建筑施工中砂浆、商品混凝土的性能受到砂含泥量等质量指标的影响,在国家、行业标准中均限制其含泥量、泥块含量指标,但目前关于砂的含泥量在商品混凝土中的影响,尚无系统的试验和足够的数据证明。因此,本文通过不同含泥量的砂配制商品混凝土进行试验研究,总结其对商品混凝土性能的影响规律,为在当地配制合理等级的商品混凝土提供试验数据和理论依据。
In construction, the performance of mortar and commercial concrete is affected by the quality index of sand and clay content, and the content of mud and clay content in the industry and the industry is limited. However, In the absence of systematic testing and sufficient data to prove. Therefore, in this paper, different amounts of sand were used to prepare commercial concrete for experimental study, and its influence on the properties of commercial concrete was summarized. The experimental data and theoretical basis were provided for the preparation of commercial concrete with reasonable grade.
