| Abstract: | In this paper,the authors made the test study and analysis on the properties of ready-mixed concrete with fine sand and pebbles.They used the principles of the low amount of cement,found out the optimized sand ratio,and mixed C25 ~ C35 ready-mixed concrete with more than 18cm slump and less slump loss.The concrete have been used in a number of local engineering with good result of using.Last,make a number of suggestions in using concrete with fine sand and pebbles in the actual construction. |
