摘　　要：采用体积设计法,试验研究了粗细集料体积比(Vcf)、细集料与水泥浆体体积比(Vfp)等体积参数对道路混凝土工作性能的影响。结果表明:通过混凝土组分中粗集料含量与水泥砂浆内细集料含量的合理组合,可以获得良好工作性能的道路水泥混凝土;在粗细集料体积比的合理范围内,适当降低配合比中的粗集料含量,并选择适当的细集料与水泥浆体体积比,也可以配制良好工作性的道路水泥混凝土。如果仅想增加坍落度,建议可以适当降低粗集料含量;或者在不大幅度变动材料比例的情形下增加减水剂的用量。Using the volume design method, effects of volume parameters on workability of road concrete were researched by experiment research. Results show that well workability of road concrete can be obtained by combining reasonable the coarse aggregate content and the volume ratio of fine aggregate to cement paste. Well workability of road concrete can also be obtained by reducing coarse aggregate content and chocking the reasonable volume ratio of fine aggregate to cement paste when the volume ratio of coarse aggregate to fine aggregate lies within a proper scope. Decreasing the coarse aggregate content or increasing the dosage of water-reducing admixture is suggested to increase the parameter of slump value.
