Make concrete from the following materials.
How can I calculate the
predict compressive strength of their constructed specimens? What
is the formula?
Thanks.
Homework Answers
You cannot simply predict the compressive strength of your mix proportion using the given data in Table 1.
If you are having the information about the grade of concrete for which this mix proportion has been designed then you can predict the compressive strength of constructed materials.
In case you are designing the mix proportions for your concrete then you should make a large no of specimens and test them in a laboratory using CTM machine and then are having the data for 7 days, 14 days and 28 days strength and depending on the data and the standard deviation you can predict the compressive strength that can be acheived by you design mix with some standard deviation.
So you need to have target strength for your specimen more than the required and degree of importance.
