What is the difference between grade 60 and grade 40 steel bars?
Grade 60 has a tensile stress of 60000 psi while Grade 40 has 40000. Grade 60 steel rusts faster than grade 40. grade 60 bar can be identified by the word 60 which should have printed on that while on grade 40 no no will be printed or written and we can identify this by counting the lines on steel as well. If there are 3 lines longitudinally on the bar its is of 60 grade and if 2 lines longitudinally it will be identified as 40 grade.
What is the compressive strength of M40 concrete?

How big is a bag of concrete?

What is the density of most of construction materials?
Does it float or does it not float? If it floats it is lense dense than water, 62.4 lbs/cubic ft. Wood is about 40 lbs/ cu.ft.--it floats. Concrete is 150 lbs. / cu.ft. -- it does not float.

How much does 100cm x 40 cm x 3 cm of concrete weigh?
It depends on the mixture of concrete. some concretes can float and some are extremely dense. The density of a concrete is dependent on the material it is made from, typically the aggregate. So without a known density for the concrete this cannot be answered.
Are Concrete Storm Shelters safe from lightning?
concrete is not a conductor of elec. a well built shelter would be steel reinforced . Much safer than a steel one Dennis Vail 40 years building of building concrete storm cellars and saferooms on site cellarman100@hotmail.com
What is a 40 out of 50 grade?
40 out of 50 is 80%. The grade which this represents will depend on grade boundaries which, in turn, will depend on the standardising procedure.

What grade does 36 out of 40 equal?
its 90%
What is your grade for 40 out of 60?
Whatever grade you get for 66%
What is the percentage of stone in the cyclopean concrete?
40%
If you have 100 and you get a 40 what is your grade now?
Assuming you only had a single grade of 100, a second grade of 40 would give you an average of 70. The grade corresponding to that would depend on what range of percentages corresponds to what grade.
What is your grade if you get 40 percent out of 100 percent?
40 (F)
