RE: Conc Spec Question

[Subject Prev][Subject Next][Thread Prev][Thread Next]

The only thing that I have ever come across for a "false set" is:
1.	The super plasticized concrete that looses its slump and bleed water
is often times viewed as a set, but it is not.

2.	The hot and dry conditions that can crust over the top, but the
concrete has not achieved a set.

I have not seen anything that is specifically in regard to Type II cements.

Let me know if you find out anything else.

While reviewing a concrete specification, I came across the following
"Portland cement shall conform to ASTM C 150, Type II including false set
requirements." Can someone define false set requirements and why it only
applies to Type II cement?
