Note: Aggregate that is not saturated to a minimum of SSD, will absorb any available moisture during transit and more so when under pressure from a pumping system.įRM advised the placement team to accept the use of three chemical additives to ensure successful pump and placement of the lightweight concrete. The Solution: Ensure that the lightweight aggregate was completely saturated at the time of production. The added pressure of pumping the concrete vertically will exacerbate the slump loss. Concrete loses an average of 1”-1.5” of slump for every 100ft of piping system.

Concrete was pumped 75ft vertically and through a total of 165ft of piping.

Lightweight aggregate absorption, 17.6% per test method ASTM C-127.

Travel time, roughly 45 minutes and an additional 20 minutes of unloading.

The Challenge: Maintain a consistent workability (slump) of the plastic concrete from the production plant to the time of placement. General contractor, Avanti & Level 10, coordinated the construction of the new entertainment center on top of Red Hawk Casino’s 8 th floor parking structure. ft slab, placed on a suspended steel deck.

As concrete supplier for this project, Folsom Ready Mix Rancho Cordova, Plant 1 supplied lightweight concrete for the 85,000 sq. The planned entertainment center will occupy 85,000 square feet of space above the northern half of the parking garage and will feature a bowling alley, virtual reality gaming suites, and indoor go-carting. Red Hawk Casino is adding a new hotel and an amusement complex this year in Placerville, CA.
