Stresses induced by a demolition agent in non-explosive

Stresses induced by a demolition agent in non-explosive rock fracturing Soundless chemical demolition agents (SCDAs) have gradually become the first choice for concrete building demolition due to its advantages in avoiding environmental damage. However, the optimal use of SCDAs in engineering practice is poorly documented. In addition, as a non-explosive method, SCDA can effectively eliminate dust, noise, Equation of hole arrangement for concrete beam demolition

Impact of thermal transfer on hydration heat of a Soundless Chemical

This paper explores thermal transfer effects in Soundless Chemical Demolition Agents (SCDA). In a 10 °C water bath, quadrupling the volume of SCDA in a pipe accelerated peak hydration onset and resulted in a 700% increase in expansive pressure and a 20% increase in volumetric expansion. Non-explosive demolition agent. Y. Kasai Properties of soundless chemical demolition agents. The traditional approach to demolish concrete structures or to reduce the sizes of large rocks or boulders has typically included the use of explosives. The resulting explosions are associated with the obvious risks posed by shock waves and fly rock. These, along with other detrimental Properties of soundless chemical demolition agents

Non-explosive cracking agents are also called as chemical (demolition) cracking agent or chemical expanding agent or soundless (silent) cracking agent or expansive mortar. Non-explosive cracking agent is a powder product consisting mainly of calcium oxide and small quantities of additives like Al 2 O 3,Fe 2 O 3,SiO 2,and MgO.
