This invention is related to a controlled expanding chemical (CEC) and its activation system. In this invention the mixture of chemicals activated by a totally electronic/electrical system to break (fracture-demolish-split) rock and concrete and hard formations; without creating any shock waves, fly-rock, vibrations and without producing hazardous gases and having no damage or harm for human and living things comprises chlorates selected from magnesium chlorate, sodium chlorate, barium chlorate, potassium chlorate as alone or mixture of two or more with ratio of 30-70% by weight of mixture, oxalates selected from calcium oxalate, ferrous oxalate, lithium oxalate, potassium oxalate, sodium oxalate, ammonium oxalate, ferric ammonium oxalate, ferric sodium oxalate, ferric potassium oxalate as alone or mixture of two or more with ratio of 5-35% by weight of mixture, sugar or lactose or starch or any combination of them with ratio of 10-40% by weight of mixture, boron oxide (boroxide) (B2O3) with ratio of 2-25% by weight of mixture, and borax decahydrate (Na2B4O7.10H2O) with ratio of 1-20% by weight of mixture. |
