Q&A about concrete and rock breaking chemicals
Our product is optimised for the breaking of concrete and rock with borehole diameters between 30mm (1¼”) and 40mm (1½”). However, we have on both sides, i.e. larger and smaller borehole diameters, a buffer zone where the expanding cement still works perfectly. When using smaller diameters it can however happen that concrete quarrying, and complex environmental rock breaking projects [4].

What is Expando? Expando
Cracking agent for rock & concrete breaking solution. EXPANDO is an expansive mortar chemical that cracks rocks and concrete, without using explosives.It is a concrete cutting, granite breaking and general demolition solution. This non-explosive demolition agent is easy to use, cost effective and a safer option for silently breaking up hard materials like produced must overcome the strength of the rock to create a splitting plane. Expansion chemicals Non-explosive expansion material (NEEM) is a controlled cracking method for mining good quality blocks of rock (Gholinejad and Arshadnejad, 2012).
