Effect of Particle Density on Its Rebound in Dry-Mix Shotcrete

Mar 28, 2006  This is a study on the influence of particle density upon the rebound of a projectile impinging via the dry-mix process onto fresh shotcrete. The empirical model developed in this study postulates that a lower aggregate density favors lower rebound and this prediction was verified using two kinds of lightweight aggregates in dry-mix shotcrete.

The mixture of shotcrete was a combination of Portland cement and fine aggregate is the ratio of 1:3. Water to cement ratio is 0.6. The results demonstrated the compressive strength of shotcrete used bottom ash as an aggregate was less than normal shotcrete approximately 45%. This is due to the particle strength of bottom ash is less than sand.
