What is the 21 days strength of concrete?
I think its 90% of ultimate strenght
What is the difference between lean concrete and mass concrete?
Mass concrete is concrete cast without Rebars. They are good in compression and are mostly used for the construction of gravity structures such as Dams. While reinforced concrete have reinforcement bars in them, which increases the tensile strenght of the concrete.

Are specific gravity of the material will give effect to strength of concrete?
The specific gravity of materials tell us how many times is the material heavier than water. The higher the specific gravity of a material the higher the density of concrete made with and the higher will be the force require to crush it and the higher will be the corresponding strenght of the concrete
How much weight will a concrete driveway hold?
The amount of weight a concrete driveway will hold without doing damage would be determined on many factors. For instance, consolidated area of weight..ie.#'s per sq. foot, concrete strenght, amount of reinfocement in concrete, compaction of soil under concrete when placed, thickness of concrete, etc. Most driveways should be able to handle a concrete delivery truck if the drive way doesnt have any abrupt edges that truck must cross and the tires stay a reasonable distance from the edges..Hope this helped..and enjoy the pool if that is your project

Why 7 days compressive strength is concider?
concrete strenght gain at first 7 days much increase so we consider 7days strenght

What kind of metal are bank safes typically made of?
Older vaults were made of steel-reinforced concrete. The walls were also very thick, which made the vault very heavy. Nowadays vaults are made of lighter and thinner concrete with additives which give the concrete extreme strenght.

What is 21 days strength of cement concrete?
concrete (cement) cures with age, well at least up to a point. think of breaking up the concrete slab that was cast yesterday evening, versus a concrete slab that is a year old. the optimum strenght of concrete (maximum strenght it is assumed to reach) is statistically reached after 28 days, if proper and adequate curing took place, and normal working / exposure conditions and control of quality took place. Curing is basically protection against severe exposures as draft winds that may cause cracking, and keeping the surface moist over the 7 days, by covering it with DPC plastic or regular sprinkling with water. after only 7 days of curing, the 28 day strenght can be accurately predicted to determine if it will pass the requirements. after 7 days (I have also seen 24hrs samples) a cube sample is crushed to determine the 7 day crushing strength. this sample was then cast at the same time as the structure being assessed. the 7 day strenght is measured in Mega Pascals (Mpa) or equivalent units Kilo Newton per square millimeter (kN/mm2) and really depends on the application the concrete is used for: walkways will probably be 10Mpa single storey building footings and floor slabs, say 15Mpa floor slabs where vehicles may drive could be even 35Mpa. Suspended slabs, like first floor slabs etc, say 40Mpa.
What Hercules symbols?
Strenght
What is an antonym for weaknesses?
strenght
Significance of grain size analysis?
grain size analysis is used to accertain the various sizes that are available in a particular sample of soil since it is required to calculate the strenght of concrete mix and also the king of soil that the sample is.
How do you write strenght in Arabic?
