Selective Demolition of Masonry Unit Walls With a Soundless Chemical Demolition Agent
Construction and Building Materials, 2020 Abstract A soundless chemical demolition agent was applied for selective demolition to unit masonry [2 full-scale concrete brick walls in Type N mortar and 2 wallettes in lime mortar – 1 historic brick and 1 concrete brick]. Typically, cracking began shortly after 9 h and ultimately produced an average crack length of 418 mm per hole and an average ...

Impact of Thermal Transfer on Hydration Heat of a Soundless Chemical Demolition Agent [PDF]
Construction and Building Materials, 2018 Abstract 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.

Structural Concrete, 2023
AbstractThe annual global building demolition is burdensome due to the rapid development of cities. The pollution associated with building demolition severely endangers the urban environment. Soundless chemical demolition agents (SCDAs) can effectively avoid environmental hazards in the demolition of concrete buildings.

Cold and Moderate Ambient Temperatures Effects on Expansive Pressure Development in Soundless Chemical Demolition Agents [PDF]
Construction and Building Materials, 2016 Abstract This paper explores cool and moderate temperature (2–19 °C) impacts on hydration heat and expansive pressure development in two commercial soundless chemical demolition agents (SCDAs). Experimental results showed (1) product-specific, linear relationships between the ambient temperature and time to peak hydration heat; (2) peak hydration ...
