| Description: | Technical Report Abstract: This report presents the results of a laboratory investigation that was conducted for the purpose of validating mixer-uniformity requirements for roller-compacted concrete. The purpose of the investigation was to verify existing guidance or, if necessary, recommend changes to existing guidance. The investigation included both air-entrained and nonair-entrained concrete. The results indicate that existing guidance is appropriate for Vebe consistency, water content, coarse aggregate content, compressive strength, and air-content determinations. However, the results indicated that existing guidance could be too restrictive for the unit weight of air-free mortar determinations. A recommendation was made to consider revising current guidance on the allowable range for unit weight of air-free motar. |
