The amount of steel required in concrete as reinforcement is measured using a formula that calculates the amount of pressure that will be put on the concrete. There are different formulas to identify the minimum and the maximum amount of needed steel, depending on if you are making a beam, slab, or column.
0%
heat of hydration should not be more than66 cal/g and 75cal/g for 7&28 days respectively
maximum spacing assording to IS 456 = 300mm
45degree maximum
Required slump for pump concrete is 100 -200 mm is suitable with used of admixture
when the pressure increases over the maximum allowable working pressure of the vessel, the valve will open to protect against overpressure.
I think that the maximum percentage of stell reinforcement in foundation is 4%
heat of hydration should not be more than66 cal/g and 75cal/g for 7&28 days respectively
concrete in very good in compression,but its capacity to withstand tension forces are comparatively very weak. steel is very good to withstand tensile forces,thats why we provide reinforcement in concrete.And the installation of reinforcement is such a way that it comes at those part of concrete where tension is maximum. second point must be consider that both matterial thermal expansivity is same. other wise we could use other metal
7% is allowable limit for plastering purpose but limit is extented to 10% for masonary works.As the availability of natural sand has become a problem,particularly in big cities.
The maximum percentage allowable is 65 percent. This can only be taken out if the garnishee does not support a second family and owes more than 12 weeks of back child support. If the garnishee does support a second family, the maximum is 55 percent if he owes more than 12 weeks of back child support, and 50 percent if he does not.
Maximum Allowable Working Pressure

The maximum allowable size that can be altered.
Maximum Actual Allowable Charge
Type I error.
Yes, in statistics, the epsilon symbol is used for maximum allowable error. http://www.liaad.up.pt/~jgama/IWKDDS/Papers/p14.pdf
