| Abstract: | Sand and aggregates that are delivered to the premixing plant are evaluated for their grading in accordance with the evaluation methods for soil particles in soil mechanics and the range of continuous grading defined in specifications. Homoge- nizing measures were taken to optimize the grading of aggregates to enhance the working performance of concrete. The optimiza- tion of aggregate grading has ensured the quality of concrete and reduced the cost of concrete. |
