摘要
对于坍落度为10～60mm的低塑性、塑性混凝土，对比分析了试验法、查表法、计算法、砂石整体级配法，在应用时，应综合考虑影响合理砂率选择的因素，较准确地选择合理砂率，以达到混凝土的技术经济性。
Test method, look-up method, calculation method and sand-gravel integral grading method are compared with each other and analyzed for low-plastic and plastic concrete whose slump is 10-60mm. Various factors influencing selection of reasonable sand percentage shall be generally considered to more accurately select reasonable sand percentage and to exert technical and economical advantages of concrete.
