Garden State Sealing Keep the Water Out
or long lasting strong concrete it is vitally im- portant to control how concrete is exposed to water. Portland cement concrete, the most commonly used build- ingmaterial is composed of four basic ingredients; Portland ce- ment, small aggregate(sand), large aggregate(stone) and water. While all are important in the initial mix and curing process, the introduction of water throughout the life of the concrete can have unde- sired effects on the concrete. The amount of water added to the initial concrete mix is F
cement ratio. This will result in a stronger denser concrete. Use a cure and seal com- pound. Curing compounds form a film on the concrete surface and maintain surface moisture throughout the cur- ing process. A cure and seal compound will aid in retaining moisture during the curing process and will also seal the concrete from future moisture penetration. Both of these options are low cost ways to ensure the viability of your concrete at the time of installation. After installation, inhibiting the reintroduction of water to the concrete is also important. Concrete sealers including silanes, siloxanes, epoxies and acrylics can be used to reduce moisture penetration. Limiting the penetration of water into the concrete sur- face can mitigate the effects of freeze thaw damage in winter months. Water may be necessary for life as we know it, but your concrete will last longer without it. Garden State Sealing is a comprehensive commercial and industrial paving com- pany serving property man- agers, owners and home owner associations. Newmark Knight Frank reps. seller in 180,000 s/f mixed- use transaction CHERRY HILL, NJ — Newmark Knight Frank (NKF) has announced that its Philadelphia Capital Mar- kets team has successfully completed the sale of 9 North Olney Ave. NKF’s Mike Mar- golis and Dave Dolan , in cooperation with Dave Ga- ronzik, Kenneth Zakin and David Noonan , represented the seller in the $13.58 million trade of the property located in Cherry Hill. The 183,000 s/f warehouse, office, distribution and lab space building was 100% occu- pied by a single tenant, Hikma Pharmaceuticals, at the time of sale. The property is a mission- critical site for the tenant, featuring a premier transit-ori- ented location in close proxim- ity to Exit 34 of I-295 and Exit 4 of the NJ Tpke. The site also provides easy access to Rtes. 73, 70 and 38, nearby regional malls, retail amenities, hotels and restaurants.
very important. For strong concrete a cement to water ratio of .4 is recommended. This means for every 100 pounds of cement in the mix, 40 pounds of water should be used. For sidewalks and residential driveways, .4 to .5 is sometimes used, but higher amounts of water can result in a more porous surface which can lead to problems later on. Concrete needs water to initiate the curing process, but this water needs to be controlled. We already know that adding too much water to the concrete will lead to
a weaker concrete. Concrete with too much water will likely not reach its design strength. Why is it important to con- trol the water? When concrete cures too fast, shrinkage cracks can oc- cur. These cracks while small and initially unnoticeable can become pathways for moisture intrusion later on down the road. The rate at which water evaporates from the concrete is important as well. If mix water evaporates too quickly, it can lead to DEF(delayed ettringite formation). Ettringite, which forms after the concrete has
cured, creates internal pres- sures on the concrete which can contribute to cracking. Whether its shrinkage crack- ing, micro cracking or a porous surface due to weakened con- crete, all of these conditions can contribute to the absorp- tion of water. What can be done to control the water? Use a low water to cement ratio. If workability is an is- sue, use a high range water reducer or super plasticizer. By utilizing a super plasti- cizer you can maintain both workability and a lowwater to
