I agree with Matt, though I don't know why you would need to look at relative regidity? These are light-framed timber shearwalls, right?
I wouldn't check relative regidity.
the question is if slump is a good indicator of w/c if there are no additives.
cvg, this question is not related to a specific w/c ratio. It is specific to a mix with no addititves.
htfptm, nothing personal, but i don't think your advice is good practice. Maybe if you're building a shed in...
The above reference is to "place" concrete. After placement there could still be a considerable time before the next lift.
Ambient temp and mix design are your two main factors determining when a cold joint will form. Are additives used to delay the set time?
As a rule of thumb, if the...
Ron,
Thanks for the response. No need to appologize for the smart a@@ comment. . .you wouldn't be a very good engineer if you didn't care about details. Besides, you're right, and i've gotten a bit sloppy with my jargon.
Anywho,why would slump not be a good indicator of water-cement ratio...
Hello,
This question has been bugging me recently: Does the max w/c ratio in ACI 318, Table 4.2.2, reference "free water" or "total water"?
Any sources for your opinion is appreciated.
("free water" being defined as "total water in the mixture minus the water absorbed by the aggregates in...
