No capping or rubber caps. The specimen is placed on the bearing block alone. I dont have the ASTM that quotes the use of the method in front of me. These sample s are cement and water only, no sand.
I still havent got access to the job specs for this grout. We are using it for tie backs.
Thank...
I am testing Grout that has been put in Mortar cube molds.(Does that make sense?)
It is for tie backs in the slurry walls for a large project.
There is no absorption of any kind during the molding process. I took a look at the molds today and couldn't tell exactly what it was made of(covered in...
Shovel full? Can you give me an example?
Also, should the planeness of the the Grout Cubes really have such a signicant variation. By say a load difference of 10,000lbs?
I have questions about Mortar Grout Cubes.
It seems extremely difficult to get consistant break strength. At times it seems to be no problem at all to make strength. Ive had several specimens that have actually gone down in strength at the second set of breaks. I have been sanding the sides...
Jdonville,
Thanks for replying. I was begining to think no one knew what I was talking about.
My next question , or actually what I originally wanted to know was, HOW can I use GIS in Geotechnical work in all it's aspects?
Hope that makes sense.
Thanks in advance.

Im Looking for information on GIS applications in Geotechnical Engineering. Ive seen a few papers written from engineers in India, but not very much from the U.S. Does anyone know of a Civil engineering firm that makes use of this technology on a regular basis?
Thank you.

boffintech,
Usually 24 hours at the most curing on site. Then transported to the lab the next day and stripped and tanked in the "curing room".
So, the answer I guess is 3. The initial curing process on site actually not known to me. I assume they are in a safe location nearby the initial...
Henri2,
Samples meaning "cylinder specimens" ASTM C-39.
Civilperson,
I did consider your conclusion. It seems the most likely, however, you'll never get a tech to admit he drop kicked a sample...
Thank you both very much.
Ive been breaking 4x8 cylinders for a very large project that requires a design strength of 8000 psi. We are getting passing #s. However, every once in a while (maybe once or twice a day) I'll get 2 samples from the same mix design that have psi breaks that are 16 to 25% difference between the 2...
