摘　　要：为达到节能减排和降低混凝土生产成本的优化目的,某水利工程混凝土配合比,在水、水泥、掺合料(粉煤灰)和外加剂几个混凝土主要组成因素已经确定的基础上,通过对当地不同砂石料料源进行试验检测对比,进一步优选砂石料源,降低了胶材和外加剂用量,节约了混凝土生产成本,节能减排效果明显。The mix ratio of concrete for a water conservancy project has been determined as several main components of concrete such as water,cement,admixture(fly ash)and additive.On this basis,in order to achieve the purpose of energy saving and emission reduction and reduce the production cost of concrete,this paper carries out tests and tests on different sand and stone material sources in the locality.The sand and stone material source is optimized,the consumption of rubber and additives is reduced,the production cost of concrete is saed,and the effect of energy saving and emission reduction is obvious.
