Use of explosives as a primary rock fragmentation is the cheapest and popular method of in-situ rock breaking. In locations where explosives cannot be used due to closeness to buildings, structures, villages etc, the only rock breaking method is 'blast-free technique'. Under the blast free techniques surface miner, use of rock breakers, and rock splitters are the techniques which are based on mechanical energy being used to break or fragment. The other method which is now gaining more use is 'use of expansion cement or chemicals' to break the rock by cracking.In India ACCONEX was the first such expansion cements which were used to crack and break any type of rocks. But since last few decades a number of expansion chemicals are manufactured and used in India. They are based on a product from limestone, added with some additives. An attempt has been made in this paper to present the use of this chemical for breaking of rocks in quarries.
