Tyler ley the greatest tutor for civil engineers I was literally amazed by this TARANTULA CURVE because here in India we make concrete by trial and error method, doing tons of tests and thus wasting a majority of our time. WE WOULD BE MUCH GRATEFUL TOWARDS YOU IF PROVIDE MORE INNOVATIONS IN CONCRETE TECHNOLOGY. (based on new research)
Hi Tyler Amaazing work, intuitively always thought along this narrative - the other model make sense to a degree, but stumbling upon this is awesome. Any chance you have a spreadsheet for the metric system? or how to convert your imperial to metric?
thanks for share your knowledge. I have a question. is it tarantula curve recommended only for two aggregates ( for example gravel 1'' and sand), because in my country this is common way to manufacture concrete at plant? Maybe we can mix with fine sand ( about 30% ) or mix with gravel 1/2''. But mixing four agregates ( fine sand, gravel 1'', gravel 1/2'' and sand) in the plant is complicated.
Ricardo, This can be done with as many aggregate sources as you want. I have found that it is rare that two aggregates will work but it is possible. Three aggregates seems to be the best combination. In some cases I have seen four aggregates used but it is not likely needed. People commonly use two aggregates because it is easy. However, that doesn't mean that it will produce concrete that can be workable with the minimum cement content. I hope this helps.
Hi Tyler, How do you get the assumption number on the percent retained as explained in minute 6:30, only assumptions of 1450 coarse, 350 intermediate and 1200 fine agg, nothing explain the gradation. how do you come out with gradation number on each sieve sizes?
You have to get the gradation for each of your different sizes. Replace the numbers in the spreadsheet with what is the actual gradation of your aggregate.
Got it. So we input based on aggregate gradation available, I was thinking of custom design gradation our own coarse, intermidiate and fine mix. Thanks...

How to have the spreadsheet?

Thanks for this beautiful video
I am glad you like it!!!

You could do that but that is not possible with many projects.
Hi Tyler, what is the best way to reach you? Can't figure out your email address.
