How to cure concrete slabs?
Pond curing is another great way to cure concrete, and the process is just as it sounds: You form temporary berms around a new concrete slab, and then flood the area inside them with one foot of water. Three days of pond curing does the work of seven days of moist curing, and without daily attention—just be sure the water level remains above the concrete slab. If it drops, you’ll need to refill a little. This technique isn’t for everyone, though, because it takes quite a bit of soil to form berms around a big concrete slab. Large-scale builders may use this method to speed up the construction process when pouring foundation slabs, for example, in order to get on to framing the structure.
How to keep concrete moist?
When you don’t have time to revisit your concrete with a hose as many times as necessary for true moist curing, another option is to use a cover that can trap and slow the evaporation of the moisture in the mix. Either polyethylene sheeting that’s at least 4mm thick or a concrete curing insulating blanket—both available from DIY stores—are good for this task. Wet the concrete thoroughly, and then cover it with the sheeting of your choice, using bricks, rocks, or other heavy items to hold it in place. Remove the sheeting or blanket daily, wet the concrete again, re-cover it, and repeat for seven days. This technique can also be used for upright concrete columns and walls by wetting them down and wrapping them with a curing blanket or plastic sheeting.
Why does concrete crack?
While curing concrete will go a long way toward strengthening the finished project, many concrete slabs will crack anyway—despite all precautions—due to concrete shrinkage as water is used up in the hydration process as well as temperature fluctuations.
How long does it take for concrete to harden?
Although concrete will harden soon after pouring, it’s still susceptible to damage from weight during the first four weeks. Wait at least 24 hours before allowing foot traffic, including pets, on a newly poured sidewalk or slab, and don’t drive a vehicle on a new driveway for at least 10 days. After that, you can drive regular passenger cars on the concrete; heavy pickups or RVs can roll onto the driveway once the concrete reaches its full strength, at around 28 days.
How to determine the spacing between concrete joints?
Determine the maximum spacing between joints (in feet) by multiplying the planned concrete thickness (in inches) by 2.5. For example, if you’re creating a sidewalk that is 4 inches deep, you’d multiply 4 by 2.5 to get a distance of 10 feet between joints. Feel free to place them closer together for added crack protection. On a larger square slab, like a patio, you’ll want to consider breaking the concrete with joints that are perpendicular, too—down as well as across. Then, if your slab patio, driveway, or sidewalk cracks, it will most likely do so along a precut joint and can, therefore, go virtually unnoticed.
What temperature does concrete go dormant?
Concrete’s chemical reaction slows at 50 degrees Fahrenheit and completely stops at 45 degrees Fahrenheit, meaning that it’ll go dormant and it won’t gain strength.

What is water reducing admixture?
Water-reducing admixtures are chemical products that when added to concrete can create a desired slump at a lower water-cement ratio than what it is normally designed. Water-reducing admixtures are used to obtain specific concrete strength using lower cement content. Lower cement contents result in lower CO2 emissions and energy usage per volume of concrete produced. With this type of admixture, concrete properties are improved and help place concrete under difficult conditions. Water reducers have been used primarily in bridge decks, low-slump concrete overlays, and patching concrete. Recent advancements in admixture technology have led to the development of mid-range water reducers.
What is corrosion inhibitor?
Corrosion inhibitors can significantly reduce maintenance costs of reinforced concrete structures throughout a typical service life of 30 – 40 years. Other specialty admixtures include shrinkage-reducing admixtures and alkali-silica reactivity inhibitors. Corrosion-inhibiting admixtures have little effect on strength at later ages but may accelerate early strength development. Calcium nitrite based corrosion inhibitors do accelerate the setting times of concretes over a range of curing temperatures unless they are formulated with a set retarder to offset the accelerating effect.
What is the purpose of superplasticizers in concrete?
The main purpose of using superplasticizers is to produce flowing concrete with a high slump in the range of seven to nine inches to be used in heavily reinforced structures and in placements where adequate consolidation by vibration cannot be readily achieved.
Why use retarder on concrete?
Retarders can also be used to resist cracking due to form deflection that can occur when horizontal slabs are placed in sections. Most retarders also function as water reducers and may entrain some air in concrete.

Biological stains are caused by living organisms such as mold, moss, and algae. They often appear as green streaks, film, or cushiony growth over a broad area on concrete surfaces that stay damp. This can be a recurring problem in humid areas, so it’s helpful to have a fast-acting, long-lasting solution.
Why does concrete stain?
That’s because most stains on concrete are created by tough materials like petroleum products, paint, and living organisms such as mold, mildew , and algae. What’s more, concrete is porous and tends to soak up these substances, so once they penetrate deep into the surface they’re especially difficult to dislodge.
