What else can I help you with?
Does the amount of water in a gravel based concrete depends on how fast it will harden?
yes, because after casting, concrete will get its 90% strength within 28 days and proper hydration require the proper amount of water for atleast 28 days.
How soon can concrete be sealed?
You should wait a minimum of 28 days before you seal concrete. If you pour your concrete in summer, than a minimum of 14 days is acceptable. If you seal concrete any quicker, there is a chance moisture will be trapped inside.
Should concrete crack within days of being poured?
It could, but it should not crack. Either the grade was not prepared properly, the concrete was used too soon, the concrete was not reinforced, it was allowed to cure too quickly, or some other problem existed.
What is m 30 concrete?
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
How long should you wait before you seal concrete?
AnswerTypical concrete takes 28 days (4 weeks) to cure. Prior to the 28 days concrete still has moisture in it that weakens the strength of the concrete. If you seal it prior to 28 days there is a chance you will be sealing in some of that moisture and hence weakening the integrity of the concrete. Another more common problem that occurs when you seal in the moisture is you can see white cloudy bloches which is really the reaction of the moisture and sealer. This prevents a strong bond for the sealer and the sealer can peal up. Ok, all that said, the 28 days really is condition dependant. If you poured your concrete in the middle of dry summer then 14 days should be the minimum amount of time you should wait. After you seal the concrete (depends on conditions and sealer product) you will typically want to give the sealer 1 day prior to walking on it and 48 hours after application before driving on it. Again depends on type of sealer (ie. epoxy...). concretenetwork.com has a lot of good info as well. Good luck.

How long should concrete cure before it can be used for construction purposes?
Concrete should cure for at least 28 days before it can be used for construction purposes.
When can you put weight on new concrete?
New concrete will need to cure for several days. Depending on how much weight it is going to hold, this should be postponed as many extra days as possible.
How long should a concrete driveway cure before parking cars on it?
At least 3 days
Should concrete crack within days of being poured?
It could, but it should not crack. Either the grade was not prepared properly, the concrete was used too soon, the concrete was not reinforced, it was allowed to cure too quickly, or some other problem existed.
Which type of concrete should you use when it must reach its design strength in about 28 days?
concrete made upof ordinary portland cement gain strength in 28days
How many days should we water rcc slab and columns?
That would depend on the kind of concrete. Normally longer is better. The slower the curing process the stronger the concrete.
What is m 30 concrete?
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
What is the waiting period to drive on green concrete?
Should wait at least 4 days but 7 would be better.
What is the maximum and minimum curing time of concrete?
minimum curing period of concrete is 21 days and maximum is 28 days
How many days does cement take to cure completely?
Generally 30 days brings concrete to to specified compression strength. Concrete may take 30 years to cure.AnswerConcrete will harden to about 80% strength in 2-3 days and close to 100% strength in 28 days. Concrete driveways should be towards the latter end prior to driving on them. AnswerAs a former concrete inspector, I would agree with the first answer. AnswerConcrete takes 50 years to completely cure and then takes 50 years to break down
