Use as a Non-explosive Demolition Agent

The hydration of quicklime is associated with an increase in volume of over 2.5 times. This property has been exploited to develop products, which, when moist- 

The product was developed in Japan in the 1970s [32.37]. Initially, mixes containing hard-burned quicklime were used. However, the expansive stress, which can exceed 5000 t/m after 48 hours was sometimes relieved by blow-outs (i.e. ejection of the lime from the hole), rather than causing splitting. 

Currently, the product is made by calcining mixtures of limestone and a flux (e.g. a clay) at temperatures of 1400 to 1500 °C. The resulting clinker is ground and used either as a powder or as cylindrical capsules. The formulation, and/or the degree of sintering, is varied to produce a range of products for use at ambient temperatures ranging from -5 to -i-35 °C.
