Using Dexpan to Break Concrete, Rock & Boulders in Cold Weather . Breaking rock and concrete in summer conditions using Dexpan is much easier and quicker as the warm conditions help support and speeds the cracking process. Using Dexpan in cold weather or declining temperatures can prevent or significantly delay the breaking of rock or concrete.
At temperatures below 10 °C, peak hydration heats were significantly lower but represented a greater multiplier with respect to the surrounding temperature. Below 10 °C, the Bristar typically produced 15% more peak heat than the Dexpan, which is not altogether surprising, as the Dexpan was only formulated for temperatures of 10 °C or more.

The method of drilling and blasting with explosives is widely used in rock fragmentation applications in underground construction projects, such as tunnels and caverns.
About 10 years ago, it was unheard of to use a heat pump in cold climates. Today, the best heat pumps for cold weather can operate at below-freezing temperatures.We are going to look into these low-temperature heat pumps and check which are the best mini split heat pumps for cold climates on the market today.. Namely, mini split heat pumps are exceedingly efficient heating …

tures up to 20 ̊C and Dexpan II for temperatures 10 ̊C to 25 ̊C. Each product was tested at 7 different ambient temperatures (2 ̊C, 5 ̊C, 7 ̊C, 10 ̊C, 13 ̊C, 17 ̊C, 19 ̊C). This paper examines the relationship between ambient temperature, heat of hydration, and expan-sive pressure in two types of SCDAs at cool and cold temperatures.
