At what temperature for a concrete curing is absolutely necessary?

It should be above 40F. Concrete goes through a chemical reaction called hydration, below 40F this process almost stops. Putting concrete blankets over the concrete can allow pours in much lower temperatures. The 40F represents the concrete temperature, while curing it produces heat so the air temperature can be cooler than 40F. Concrete can be poured below freezing but it needs to be protected with concrete blankets to hold in its heat. If the water in the concrete freezes before it is cured than it will definitely fail.


What is the purpose of a toilet?

Are poured concrete walls better than concrete block walls?

It depends on the application. For homes, masonry is fine as long as it is insulated well against the weather. Masonry rarely needs maintenance. Concrete walls are stronger and last longer than masonry but are more costly to construct. For basement walls, I suggest that you always use concrete walls. Above ground level, masonry is cheaper and strong enough for residential and commercial, multi-story applications. For retaining walls, 8" thick masonry works well up to about 8 feet of retained earth. Above that, the lower courses of block will get thicker to 12". You still need concrete footings for block walls.


What is the top layer of concrete called?

The top layer of concrete is called the structural coat. It directly receives the most load which must then be transferred to lower layers.


What is size effect in concrete?

The size effect in concrete refers to the phenomenon where the strength and behavior of concrete structures vary with their size. Generally, larger concrete elements tend to exhibit lower strength and increased brittleness compared to smaller ones due to the statistical distribution of flaws and defects within the material. This effect is particularly significant in tension, where larger structures may fail at lower stress levels than smaller counterparts. Understanding the size effect is crucial for ensuring safety and reliability in the design of concrete structures.

How do you repair toilet bowl mounting flange?

depending on your type of flange and pipe and the damage of the flange, if you have a PVC flange with just the bolt slots busted then you can screw in new bolts to the floor below the flange and still use the flange but if its broken where the wax seal sits then if your flange is lower then the floor you can use a insert flange that fits inside your old toilet flange with thin walls to keep the pipe size maximum. To replace the entire flange can be a job especially if its in concrete or in a floor joist because most of the time you have no room and if its cast iron pipe it can be even more of headache but in order to replace the flange you need to cut it out to where you can reconnect the pipe and flange by using a fernco or a no hub band. Sometimes it is impossible to replace because the flange can be on all close fittings and you pretty much have to replace most of the plumbing drain pipe to replace it properly which is why you want to try repairing your toilet flange rather then replacing it .
