对以长江粉细砂制造固结集料及其配制的混凝土进行了研究。结果表明：采用长江粉细砂和石灰，经混料、成球、蒸压可制得性能较好的粉细砂固结集料；由这种集料可配制出Ｃ２０ 等级左右的混凝土；以此方法制得的固结集料其价格可低于外地运沪石子的价格，具有一定的社会经济效益。 The manufacture of consolidated aggregates and their formulated concrete from the fine sand of the Yangtze River was studied. The results show that the fine aggregate with good performance can be obtained by using the fine sand and lime from the Yangtze River; the concrete with C20 grade can be prepared from this aggregate; The consolidated aggregate produced by this method can be lower in price than the price of foreign stone shipped from other places in the world and has certain social and economic benefits.
