ABSTRACT
This paper reports the effects of the type and dosage of accelerators on
the strength development of shotcrete based on field and laboratory tests. It
was learned that, the compressive strength of shotcrete is proportional
to the compressive strength obtained by the laboratory test, regardless
of the cement content, accelerator type, and accelerator dosage. Accordingly,
estimation of the strength of shotcrete is deemed feasible by using the
proposed method adopted in this study.
Key words:
Shotcrete; Compressive Strength; Porosity; Type of Accelerator; Dosage
