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

How many types of cement?
there are 3type of cement1)opc (ordnary portland cement) 2)PPC (pozolan portland cement) 3) special cement
What are the different types of cement?
Type-I - Ordinary portland cement used in general constructionType-II - Portland pozzolana cement , moderate heat of hydrationType- III - Rapid hardening cement used for quick setting worksType-IV - low heat cement, low heat of hydrationType-V - Sulphate resisting cement used in sewage linings,marine construction.
What is the dry density of cement?
The cement density is used in the calculation of the total aggregate content and of the concrete density.Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.
What is the setting and hardening of cement?
Setting of cement is the initial solidifying of the cement. I presume you will not be using a cement material by itself, but by mixing in aggregates and fines to create 'concrete' I will continue this answer talking about concrete but much still applied to a simple cement mortar also. Depending on temperature (warm fast, cold slow) initial set will be between 2 and 24 hours. This will result in a concrete material that can easily be marked with a fingernail. Once the concrete has set, the concrete goes through a process called curing or 'hardening' where the pozzolanic constituents of the concrete 'hydrate' (react with the water) to create a hard material. This will continue for the life of the concrete but the most significant strength gains will be noticed within the first 28 days and this is the strength normally taken as the design strength of the concrete. It can be expected in ideal conditions with warm air and a light breeze in the air, for the concrete to achieve 30% of it's 28 day strength in 1 day 60-80% in 3 days 80-100% in 7 days and 100-% in 28 days Many factors will affect this. temperature will have a large impact. additives such as retarders and accelerators can be added to slow and speed up the hardening process respectively.
