作为“普通、重型和大体积混凝土比例选择标准规程”（ACI 211.1）的补充。本标准描述了坍落度在0至3英寸范围内且稠度低于该范围的混凝土的配比程序，适用于最大尺寸不超过1英寸的骨料。描述了测量此类稠度的合适设备。提供了与ACI 211.1中类似的表格，以及细骨料和粗骨料物理性质的实验室试验，提供了获得试验混合料混凝土比例的信息。给出了使用这些表格的例子。 附录提供了所有表格数据到公制单位的完整转换，并显示了使用公制值解决的示例问题。

Intended as a suuplement to "Standard Practice for Selecting Proportions for Normal, Heavyweight and Mass Concrete" (ACI 211.1). The standard describes a procedure for proportioning concretes having slumps in the range of zero to 3 inch and consistencies below this range, for aggregates up to 1 inch maximum size. Suitable equipment for measuring such consistencies is described. Tables similar to those in ACI 211.1 are provided which, along with laboratory tests on physical properties of fine and coarse aggregate, yield information for obtaining concrete proportions for a trial mixture. Examples of the use of these tables are given. An appendix provides complete conversion of all tabular data to metric system units and shows a sample problem worked out with metric values.
