• RAPID CITY, S.D. (AP) -- A professor of civil and environmental engineering at the South Dakota School of Mines and Technology plans to give something back now that he's retiring.
• Marion R. Hansen is donating his accrued sick leave to create an endowment that will continue to fund research he has been conducting on concrete.
• Hansen started the program with his unused-sick-leave payout of $20,000, after taxes, the Rapid City Journal reported (http://bit.ly/10NUhKm ). He hopes to match it by raising $20,000 more through a series of themed retirement parties and fundraisers.
• "Having a lot of money makes me nervous," Hansen said. "I figured the best thing to do was pay the taxes on it and give it to the school. We don't get any money at all from the state taxpayers. All of it comes from student money or fundraising, with a little bit from student fees."
• The school's American Society of Civil Engineers student chapter needs $20,000 just to operate, Hansen said.
• Hansen has spent nearly 30 years trying to find unusual and innovative ways to use concrete, including making planes and canoes out of it and making concrete that automatically fixes its own cracks.
• He has installed concrete around Rapid City that allows water to pass through it and reduces runoff. Green concrete is another one of his innovations. It uses ash from the flue of coal-burning plants to replace some of the cement in the concrete mixture.
• Hansen recently advised a group of students who made aeronautical history by flying and landing the first concrete airplane.
• Outside, behind the lab, a pile of concrete slabs and pillars and broken pieces sits as a monument to the work of this semester's students.
• "We like to break things," Hansen said. "Make it and break it; that's our mantra."
