IRMCA presents Ken Mulzer, Sr. with the E.B. Rayburn, Jr. Award

INDIANAPOLIS – The Indiana Ready Mixed Concrete Association (IRMCA) presented Ken Mulzer, Sr., Mulzer Crushed Stone, Inc., with its prestigious 2018 E.B. Rayburn, Jr. Award. The award was established to recognize outstanding leadership and innovation in marketing efforts in the ready mixed concrete industry in Indiana and was presented during the recent 2018 IRMCA Short Course Program.

Ken Mulzer, Jr. poses with his father, Ken Mulzer, Sr. after receiving the E.B. Rayburn, Jr. Award.

Ken Mulzer, Sr. is a retired construction materials executive who, alongside his four siblings, helped grow the family aggregate business into an industry powerhouse in the production of crushed stone, sand and gravel, including concrete and asphalt services. The family business got its start in 1935 when his father Arnold and uncles Edgar and Roland formed Mulzer Brothers, a small construction firm. In 1978, the company, led by Arnold, transformed into what is known today as Mulzer Crushed Stone, Inc.

Mulzer Sr. began his career at a young age doing odd jobs around the quarries and concrete plant. He went on to graduate from Valparaiso University with a degree in Business Administration and a minor in Geology before returning home to join the family business. Over the years, Ken has been a staunch advocate for the construction materials industry on the local, state and national levels, he has served as Chairman of the Board of the National Sand, Stone & Gravel Association, been a past President of the Indiana Mineral Aggregates Association, and has held numerous leadership roles in industry and community organizations near and far from his home in Santa Claus, Indiana, which he shares with his wife of 50 years, Andrea (Dee).

“The company and I are extremely proud of my father and the role that he has played in moving the concrete industry forward over the years,” commented Ken Mulzer, Jr., President of Mulzer Crushed Stone, Inc.   “His intuition and foresight of the ever-changing business landscape proved invaluable to our firm and countless others throughout the state.”

The Indiana Ready Mixed Concrete Association (IRMCA) supports and promotes the use of high quality Portland cement concrete in pavements, parking lots, structures and residential construction. The IRMCA provides technical and informational support for its members and their clients. For additional information contact Jerry Larson, executive director, at (317) 733-1902 or see:

Mulzer Crushed Stone, Inc. Hits Million Hour Safety Mark

Mulzer Crushed Stone announced today that employees have completed 1.4 Million work hours without incurring an occupational injury or illness that resulted in days away from work or death.  “This momentous milestone is being celebrated company-wide and is a testament to the safety driven goals put in place by our management and executed by our entire team, making Mulzer Crushed Stone Safety a way of life,” commented President Ken Mulzer, Jr.

Creating a culture of safety with milestone results in a construction materials business is not always an easy road to navigate, but Mulzer Crushed Stone has a team of Safety Professionals who are known around the workplace for creating fun, innovative programs and techniques to train and educate employees on all things safety.  For example, our Team has found that a little competition can go a long way in classroom training over topics that can often be somewhat lackluster.  Who doesn’t love a good video game or quiz contest against your co-workers?

Other unique aspects to the Safety Program include designated equipment specific training employees who instruct, monitor and test new employees to verify that they are ready to work independently.

“If you think about it, quarry, asphalt and concrete operations can be highly dangerous work for a multitude of reasons, but our employees take the topic serious and make safety priority #1,” Mulzer, Jr. added.  “They don’t get complacent. We have 1.4 Million hours of zero lost time to prove it and we congratulate each and every one of them on this significant achievement.”

To further illustrate the 100% safety culture mindset, employees have been encouraged to share their safe practices in action via social media with the #MulzerSafetyMillion.

Students from South Perry Headstart Preschool visited us last week on one of the coldest days of the Spring season so far. The rain stayed away and the kids had a great time learning about what we do at Tower Quarry and seeing some of our equipment up-close. Each student also left with a new friend, their very own Pet Rock.
