伴随着城市建筑的日益增多，天然砂的供应量日趋紧张，机制砂取代天然砂是必然趋势。但机制砂由于自身的特性，在实际施工中需要注意很多问题。特别是机制砂混凝土的工作性能和强度性能，对机制砂的推广应用具有重要的决定作用。
伴隨著城市建築的日益增多，天然砂的供應量日趨緊張，機製砂取代天然砂是必然趨勢。但機製砂由于自身的特性，在實際施工中需要註意很多問題。特彆是機製砂混凝土的工作性能和彊度性能，對機製砂的推廣應用具有重要的決定作用。

Along with the increasing of the city construction, supply of natural sand is becoming tenser, so it is the inevitable trend to replace natural sand with manufactured sand. But bec-ause of its characteristics, the manufactured sand needs to pay at ention to in the actual construction. The working performa-nce and strength properties of the concrete have an important <br> role in the popularization and application of machine-made sand.
