In this experiment, it is examined whether low quality aggregate can be effectively used by the following two methods. One method is to adjust mix proportion of concrete in order to cover the defect of using low quality aggregate. In another method, good quality aggregate is mixed with low quality aggregate in order to improve the average characteristics of aggregate. Although the problem is not solved completely by these methods, there seems to be the possibility of using the low quality aggregate by properly adapting these methods according to the required properties of concrete.}, pages = {101--110}, title = {低品質骨材の有効利用に関する基礎的研究}, year = {1989} }
