This new headquarters office building and warehouse for Barrier One International and their wholly owned affiliate, Concrete Moisture Solutions, was completed in December 2016. The Building required a unique structure reflecting their vision of current and future requirements. It was designed using 50% slag cement and 50% portland cement in all concrete applications including; foundation, slab-on-grade, paving, sidewalks, casting beds, and tilt-up panels.

Slag cement was used in all project concrete for its general beneficial effect on the plastic and hardened concrete properties. The project was originally designed to include both Fly Ash and Slag Cement.  However, concern over Fly Ash availability in Florida moved the design to the current mix of slag and portland cement. All slag cement mixes over-achieved required strength designations, reaching over 6200 psi (4000 psi requirement). Of particular interest was the superior performance of the tilt up concrete where early lifting strength was required. Additionally, the mix design contributed to the ease of placement for pumped casting beds by creating a cement paste with a more desirable texture.   

The project was completed on schedule and the overall appearance of the concrete paving and sidewalks with 50% slag cement met the approval of all associated with the unique building.  The warehouse floor at 50% slag cement has met and exceeded the durability and performance requirements. The tilt up concrete employed boards to “stamp” the concrete to appear to consist of bricks or block.

The flexibility of slag employed in each mix helped Preferred Ready/Mix company respond with slag mixes for each unique concrete requirement and employ the most cost effective and aesthetic solution to the customers’ requirements.
