Concrete pavement contractors and public agencies often choose Rapid Set® Mortar Mix Plus because its integral corrosion inhibitor protects reinforced concrete and it’s air-entrained for freeze-thaw durability. Here, Earth Structures used the very-rapid-hardening repair material to quickly eliminate washboarding in a New York City parking garage.
The U.S. military has used Rapid Set® calcium sulfoaluminate (CSA) cement-based products to quickly rebuild runways and other damaged infrastructure for almost two decades. This Concrete Mix project demonstrates the material’s speed and strength benefits in one of many airfield pavement repair applications.
When concrete pavement in a new construction project hasn’t been installed to specifications, there’s not much time to remediate the issue when the owner – in this case, a commercial real estate developer – wants to open the property on schedule. That’s where fast-setting Rapid Set® Mortar Mix Plus came in.
When a tall truck took out a Texas bridge, the state DOT wanted new concrete cross beams placed within 24 hours to minimize traffic disruption. The deadline was met because Hunter Industries used Rapid Set® Concrete Mix, Rapid Set® FLOW Control, and Rapid Set® SET Control to make the 10 concrete pedestals required to support the cross beams.
A concrete plinth protects mechanical equipment from floodwater and the floor slab below by evenly distributing the equipment's weight. Here, contractor Gonzalez-De La Garza & Associates used Rapid Set® Concrete Mix, FLOW Control, and SET Control to install 4000-psi concrete pads over an existing slab as part of a boiler installation at Fort Sam Houston in San Antonio, Texas.
The structure’s 9'x7' cells had to be pitched at 25 degrees, from 1.25-inch down to ¼-inch. Aggressive diamond grinding was used to make the surface porous. After grading, Sure-Flex epoxy was used. Mortar Mix Plus, SET Control and FLOW Control were used.
An East Coast city used Rapid Set® DOT Concrete Mix to rehabilitate a structural component rather than replace an entire bridge. SW Construction Enterprises used several techniques to promote concrete workability in temperatures ranging from below freezing to 90 degrees Fahrenheit.
During the store remodel, workers had to perform extensive surface prep prior to the TRU installation. Cement All was used for the repairs and TRU Self-Leveling with integral colors were used as the polished concrete overay. The final surface was polished to an 800 grit and sealed.
Mortar Mix Plus (MMP) was used to level an elevated-deck bus exit ramp. Since this was a fast-track project and MMP achieves 3,500 psi in 3 hours, the contractor was able to meet the deadline.
The runway lights on the airfield needed to be replaced, and spec requirements required a product that would be close to 5,000 psi in a 24-48 hours. After Concrete Mix with Flow Control and Set Control showed 7,900 psi in 24 hours, the material was used in the replacement of 26 lights. By using two bags at a time, the project schedule dropped from two months down to three weeks.
Concrete Mix was used to level the seven concrete pads inside this airport's electrical and mechanical rooms. SET Control was used to extend the working time due to the hot temperature setting time and FLOW Control was used to enhance the flow consistency.
Tri-State Underlayments/Franz Floors only had four days to restore 1,200 sq ft of the existing flooring before interior framing began. For this reason, the contractor chose to use Rapid Set cement products to install the flooring, because they set quickly to produce 3,000 psi in one hour and full strength of 8,000 psi in one day. Products used include Concrete Mix, FLOW Control, SET Control, TXP Primer, TRU Self-Leveling.
DOTs are tasked with deploying new techniques and new products to extend pavement in timeframes that reduce traffic interruptions and lane closure times. Rapid-hardening cement helps them meet this challenge, since it sets and gains strength rapidly. Products used include Cement All, Mortar Mix, FLOW Control, Low-P Cement, and Rapid Set Cement.
