Title: Discrepancies Between the Volume of Fresh Concrete at the Ready-Mix Plant and the Volume in Final Placement
Author(s): Herbert J. Knopel
Publication: Journal Proceedings
Appears on pages(s): 649-656
Abstract:Rapid growth of the ready-mixed concrete industry has entailed production and service *problems. These include technical problems of preclslon control. Ab- solute volume method for deducing resulting yield of wet mixes is sound. Wet mass is altered by evaporation losses, by densification due to agitation, and by bleed- ing throu h forms or subgrades, these varying with degree of manipulation. Purpose of this paper IS t o show where these losses may occur.
