Question about concrete.

I don't know what your question really is.

A concrete contractor, would say you have to 'Puddle' the concrete to remove the entrained air. usually done with a vibrating tool.

you don't just mix and pour and move on.

I need comparing workability and strength values. Maybe some can't see quesiton, I give link

What is your reasoning??

You have provided your guesses at answers, but you have not explained your reasoning...Why do you think these are the right answers? Is this the way you talk to your teacher?.....If you don't have a clue what the answers are, then why don't you just go back over the material and study a bit longer....? Too busy being rude to people on line?

Do your own homework! This is NOT a homework cheat site.

Do your own homework. CR4 is not a homework cheat site; however, if you have questions about understanding concepts or how a portion of a problem is derived, these types of questions will be accepted.

You are also rude and demanding and not worthy of our help.

Guys am I rude or you? I asked question and I said my guess about question. If you asked me about it(solution or steps), I would explain. But instead of this what is the reason to ask question? is it so important? Yes it is homework.

Anyway I want explain my thought;

I know air entraintment decreases comp. strength so: 3 < (1 and 2) but I am not sure 1 &2 (I think that air content ASLO decrease strength so 1>2>3)

Also Air entrainment increases workability -direct proportion- 3 > (1 and 2) and I have doubt (air content increases workability) 3>2>1?

.......this isn't going well..

@phoenix911 ,asking question burgerking instead of you, I am sure they can help more than u.Too much talking, zero help. Please dont reply my thread.

I would suggest a summer job as a laborer on a concrete crew!

There you will learn terms like, "Soup it up!" "Gimme 5!" and of course "Beer Thirty!"

If you don't get heat prostration from 'hogging mud' in 100 degree heat and 100% humidity maybe you will learn of art of hard work too...and carrying your own weight.

I don't take advice dear respectful professors, I only want to take answer of this question.

please remove thread. stupid and unrelated answers contunie. only thanks to fredski for useful video. others don't know anything about it, and make foolish comments.

lol, your problem, you wouldn't know an answer if it was right in front of you.

What about "We won't do your homework for you" don't you understand? It's in the CR4 Rules pal.

Read your requisite textbook, or talk to the Professor. Frankly, if I were the Professor for this class I'd give you a "F" (as in Failure), just for trying to get one of us to supply you the answer(s).

SMH, don't they ever learn?
