How to Carry out Controlled Blasting of Rocks? [PDF]

The main objectives of controlled blasting techniques are to minimize the overbreak and fracturing of rock beyond the designated boundary of excavation to achieve smooth post-blast surface and to control wild flyrock and ground vibration within permissible limits. This objective is normally achieved by minimizing and making judicious use of explosives in the blast holes. []


Classification of Aggregates Based on Size and Shape

The angular aggregates consist well defined edges formed at the intersection of roughly planar surfaces and these are obtained by crushing the rocks. Angular aggregates result maximum percentage of voids (38-45%) hence gives less workability. They give 10-20% more compressive strength due to development of stronger aggregate-mortar bond.
