Temperature extremes make it difficult to properly cure concrete. On hot days, too much water is lost by evaporation from newly placed concrete. If the temperature drops too close to freezing, hydration slows to nearly a standstill. Under these conditions, concrete ceases to gain strength and other desirable properties. In general, the temperature of new concrete should not be allowed to fall below 50 Fahrenheit (10 Celsius) during the curing period.

It depends. High temperatures (90F and above) cause concrete to set faster. High temperatures also reduce the strength of concrete. Strong winds and low humidity can also cause problems with plastic shrinkage and drying shrinkage cracks, even at moderate temperatures. To avoid these problems, planning, timing of the finishing operations, proper use of retarding admixtures, and proper curing are necessary. More... See similar questions...

Placing hot pans on the concrete countertops should be avoided. Concrete is very heat resistant, but the concern (like with cutting on concrete countertops) is damaging and or discoloring the sealer. We can build in trivets of stainless steel, brass, or copper. This common upgrade is both functional and great looking. Otherwise, you should use hot plates or a hot pad. See similar questions...

It depends. First of all, there is no getting around the fact that the ideal temperature range for pouring concrete is 40? to 80? F. However, high quality concrete work can be done at temperatures above that range. High temperatures cause concrete to set faster. Strong winds and low humidity can also cause problems with plastic shrinkage and drying shrinkage cracks, even at moderate temperatures. See similar questions...

Yes. The AMVIC forms are used to allow builders to pour a solid concrete wall. However, upon completion, the forms are designed to provide insulation, nailing surfaces, and a vapor barrier, all in one step. See similar questions...

Concrete is a commonly requested material. To be honest, we don't know much about gluing to concrete. You could check with some building sites. Cement is the adhesive that holds concrete together. It will take some research on our part but we are thinking about doing concrete. A very cool and specialized glue! It does its job then you can roll it into ball and ... well, have a ball with it. The glue that is used for "tip ins" (magazine jargon) is referred to as a Peel and Stick glue. See similar questions...

We can add depth to the areas needing support and add rebar to strengthen the concrete for the additional load. Metal screw jacks are often used for support posts. See similar questions...

Normal concrete is designed with a flowable workability, which means it can be conveyed to the pour site using smooth rounded chutes and still maintain its composition and not segregate. Adding more water to make it pourable usually causes segregation, not to mention the adverse effects of the additional water on the strength of the concrete. To make concrete more flowable or "pourable", without adversely affecting the strength, one would add a Super Plasticizer admixutre. See similar questions...

It depends. Concrete will not set when the concrete temperature is below about 35F. Many times specifications will say something like "Concrete may not be poured when the temperature is 37F and falling." With heated water and aggregates, accelerating admixtures, and other methods, jobs can be poured below freezing, but it is more expensive. In most southern states there are so few freezing days that it is not worth it to try to pour when the temperature is below freezing. See similar questions...

Pre-pour planning and special precautions are required to assure successful placement of concrete in hot weather. These precautions may include lowering material temperatures, utilization of retarding admixtures, rapid transport and placement, and proper curing. See ACI Committee report 305 on Hot Weather Concreting. See similar questions...

In general; reduced costs, time savings and superior quality and durability can all be expected when utilizing a precast concrete utility vault. Because precast concrete utility vaults are produced in a controlled environment using higher strength concrete, the thickness of walls and area of steel can often be reduced when compared to cast-in-place designs.

If moisture conditions are acceptable, two of the most widely used applications would be engineered hardwood floors glued direct with the proper adhesives, and floating engineered flooring types. The latter typically glued by tongue and groove and floated over a foam cushioned underlayment. Floating floors are also available in the click together style that require no gluing.

Answer: Well yes, but-- Concrete is heat resistant but can be subject to thermal shock if a red hot object is placed directly upon it. Like granite, the exposed area may flake or chip away if too much heat is applied. We recommend using trivets for hot cookware. See similar questions...

Concrete can be placed at various temperatures if precautionary measures are taken. In extremely cold weather, concrete should not be allowed to freeze until it has gained sufficient strength to withstand the damaging affects of freezing. Concrete will lose its workability and set up considerably faster in hot weather. Please refer to CIP 12 for more information on placing concrete in hot weather. See similar questions...

Hot Sauna Plan Information: NO. There is no significant heat loss through the floor as the floor temperature in a hot sauna is normally about 80?F (27?C). A framed floor with insulation will eventually trap moisture & smell musty. ...Answers Pertti. See similar questions...

Concrete pavers won't be as cool as a cool deck, but it will be the next coolest thing that can be used instead of cool deck. In fact cool deck isn't as cool as it used to be because of the requirement to remove the asbestos used to give it some of its coolness. Being individual pieces, concrete pavers won't build up heat like a solid sheet of concrete and that heat will tend to dissipate between each stone making pavers a cool product to use around a pool.

By testing our concrete, we have found that leaving a boiling pot of water on our finish will not damage the finish. However, we recommend using hot pad or trivet for pots and pans coming from the oven or stove. Our recommendation is to just use standard kitchen countertop practices and your top will have a long life to it. See similar questions...

The Space Place has no climate control of its own, thus the temperature of the room in which The Space Place is set up determines the temperature inside the dome. But, because the inflation fan keeps the air circulating continuously through the dome, it is usually several degrees cooler inside The Space Place than out. Even so, in very hot climates, it is best to set up The Space Place in an air-conditioned room. See similar questions...
