在砂石骨料混凝土系统方案优选中受到多种条件的制约，所涉及的因素多而繁琐。

The factors in this field with which we are concerned are many and various .

该工程采用灰岩轧制的人工砂石骨料，将石粉含量控制在13%～17%，改善了碾压混凝土的性能。

In the artificial aggregates made of limestone , the content of stone dust was limited in the range of 13 % - 17 % to improve the properties of the RCC .

因达到使用年限或由于城市建设的需要等原因，许多混凝土建筑物、构筑物被拆除，产生大量的废弃混凝土，其中砂石骨料占三分之二以上。

Being service life or requirement of urban development , a great deal of concrete buildings , constructions are demolished to produce lots of abandoned concrete , more than two thirds among which is aggregate of sand and stone .

随着建筑业的迅速发展，混凝土的用量越来越多，而由此产生的天然砂石骨料资源的匮乏与建筑业产生的垃圾空前增加的趋势日益严重。

With the quick development of building industry , the value of concrete is demanded more and more greatly and the resource exhaustion due to the exploitation sand and stone aggregate as well as the value of construction wastes is increasing severity .

根据施工废水的污染特性，本文确定了溪洛渡水电站施工期生产废水具体的处理工艺：砂石骨料废水采取絮凝沉降与重力浓缩和过滤相结合的方法进行处理；

In reference of the polluting characteristics in construction period , the detailed workmanship of wastewater treatment had been determined , the treatment of wastewater from the aggregates of the batching plant would be carried out by means of combination of flocculating settling , gravity thickening and filtering ;
