Shotcrete was a mortar or con
crete that is pneumatically projected at high velocity onto a subject. Ithas been applied for tunneling, underground big-spaces, slope stabilization. Shotcrete is increasing use instructure repair. The dry-mix shotcrete require a smaller equipment, easy maintenance, possible of very-earlystrengthmaterials than wet-mix shotcrete, which make this process attractive and economic for structural repairs.It is common practice core compressive strength to the dry-mix shotcrete quality control. This test is verydifficult estimating eraly-strength of Very-Early-Strength Dry-Mix Shotcrete. The purpose of this research was toanalyze the correlation of test results among cube test, core test, pullout test and maturity. The correlationshipanalysis of test results among cube test, core test, pullout test and maturity showed more than 90%. (ÀÌÇÏ »ý·«)
