Abstract Soundless chemical demolition as a novel and promising demolition method shows great potential to be applied in the engineering field. However, the demolition effect greatly depends on the hole parameters. In this paper, the influence of three hole parameters (hole diameter, hole depth and surrounding constraint) on the development and ...

Properties of Soundless Chemical Demolition Agents
Journal of Construction Engineering and Management, 1994The 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 side effects of using explosives, have increased an interest in the

Enhancing Performance of Soundless Chemical Demolition Agents
Journal of Construction Engineering and Management, 1996Soundless chemical demolition agents (SCDAs) have been used in a variety of circumstances where other more conventional means of demolition were not feasible. When compared with conventional explosives, SCDAs are not yet economically competitive. Research was conducted on SCDAs to examine the possibility of adding an inert material (sand) to the SCDA ...

In demolition process of large concrete structures, the non-explosive methods can be advantageous in reducing noise, vibration, and dust emission compared to the conventional explosive methods. One of the representative non-explosive methods is the injection of soundless chemical demolition agents (SCDAs) into the holes drilled in concrete structures ...

Explosive-free breakage of biaxially loaded rock using soundless chemical demolition agents
2023The method of drilling and blasting with explosives is widely used in mining and civil engineering projects such as subsurface space construction and mine development and production. Nevertheless, there has been a growing interest in explosive-free rock breakage methods in the last two decades due to the transition to low-carbon economies and green ...

Drilling and blasting with explosives is a widely used technique for rock fragmentation in the mining industry for mine development and ore production. However, the use of explosives is associated with rigorous safety and environmental constraints as blasting generates greenhouse gas emissions, ground vibrations and dust.

ProcessesIncreasing the diameter of the drillhole can facilitate drillhole breakage using soundless chemical demolition agents, but it is prone to cause drillhole blowout, resulting in crushing failure. This paper conducted a blowhole prevention test on a large borehole using the internal insertion cooling pipe method (ICBPM) to test the expansion pressure of ...
