3 Benefits SmartRock® Plus Gives Flatwork Contractors

Simply put, SmartRock® Plus is a rugged concrete maturity system, coupled with powerful reporting and data sharing capabilities, and real-time temperature monitoring. As with all maturity systems, the contractor can benefit from knowing real-time strength allowing him to post-tension decks, strip forms, or open pavements to traffic sooner. However, with the ease of real-time temperature monitoring in SmartRock® Plus, contractors have found a few new unexpected benefits.

Reduced Plastic Shrinkage Cracking: By coupling the real-time concrete temperature with the standard nomograph for estimating evaporation rate, contractors can quickly see if they’re concrete is at risk of plastic shrinkage cracking. Especially in warm dry weather, this can tell the contractor when they need to protect the concrete with either an evaporation retarder or a fog spray to reduce the evaporation rate and prevent cracking.

Reduced Delaminations: Another summertime phenomena, delaminations occur when the surface of the concrete dries or stiffens faster than the body of the concrete which fools the finishers into getting on it too soon. By using two smart concrete sensors, one with the thermocouple near the surface and one measuring temperature in the middle of the concrete, contractors can see when the concrete is setting and when it is crusting. If it is crusting they can reduce delaminations by simply waiting to finish the concrete and thus avoiding trapping the bleed water below the surface.

Reduced Mix Cost: By purchasing SmartRock® Plus mixtures from their ready mix supplier, contractors are more able to match the performance of their concrete with their construction schedule. At the beginning of the project, when they submit their mixes, they are submitting a range of mixes that might work in a post-tensioned application, for example. Then as they start the project they can use any mix that meets the 28-day design strength, but also meets their early strength requirements. This allows contractors to not always pick the richest mix for their post-tensioned work. Which means they’re saving money on their concrete, while also saving money on finishing costs by using an easier to finish concrete mixture.

The Importance of Monitoring Temperature Differentials in Mass Concrete

Closely monitoring concrete temperatures is critical for ensuring proper strength development of concrete structures, regardless of their application or size. However, when it comes to mass concrete structures, temperature differentials also need to be considered due to the risk of a large difference between the relatively hot internal temperature and cool surface temperature. If a too-large temperature differential occurs, the surface of mass concrete will start cracking, which is detrimental to its…

Rebound Hammer vs. The Maturity Method: Which Should You Choose?

Schmidt/Rebound Hammer Method The concrete rebound hammer test (often referred to as Schmidt Hammer) was invented in 1948 and is still a popular choice to test the compressive strength of concrete. To use this method, the rebound hammer must first be calibrated against a steel test anvil. Once calibrated, a spring release mechanism is used to activate a hammer which impacts a plunger to drive into the surface of the concrete. After…
