Ron. I understand that the accuracy of the compressive strength is limited with this test. This test was used to check uniformity across a slab. I was just using the average to show the estimated psi average. I was looking for an excel program to put the numbers into rather than converting...

I am looking to simply convert the rebound number to psi. I have a bunch of test data to convert.

Does anyone have an excel conversion for rebound hammer test?

Thank you for your responses. Manufacturer of impact echo also agreed with the 1 ft grid.

We are looking to use an impact echo method to check an existing slab for thickness, as well as cracks and voids. The idea was to set up a grid, an analyze each grid center. Is there anywhere that states what size grid is recommended for this type of application? I was thinking 1ft x 1ft grids...

I have a foundation that the customer wants to raise the existing floor level. The anchor bolts see strictly shear load. I have used coupling nuts in the past when the bolts were loaded in tension. I have tried finding rating for coupling bolts in shear but have been unsuccessful. Has anyone...

I have a potential project in a permafrost area. I have little info known yet on the site. We would like to have an underground concrete bunker for equipment. Customer has fear of installing an underground bunker due to chance of uplift of the bunker. An idea I have that I wanted to get some...

My concrete books have shear as Vc = 2λ√fcbwd.

bimr, This degree does qualify. You were looking at the section pertaining to graduate level engineering curriculum. This degree does qualify under the ABET accreditation. I have this degree, and I was able to sit for my FE exam. This degree is one that is allows someone to take the degree at...

bimr, The Construction Management Technology Program is accredited by the Engineering Technology Accreditation Commission (ETAC) of ABET. Therefore it is ABET accredited. You are able to sit for the FE and PE with this degree in the state of PA.

Temple University has a Construction Management Engineering Technology Degree offered through department of Civil Engineering. This degree was previously called Civil and Construction Engineering Technology. This degree can be obtained part time at night. And you can sit for your FE and PE with...

I work for a company that is based in the U.S., but we do work all over the globe. We have some standard designs that we use, and one of the new compatibility requirements is the use of 5000 psi concrete. My question is what kind of availability do you think is out there for this strength concrete?

Has anyone ever used the "Concrete Tester and Surveyor (CTS-02)"? It is made by the Nitto Construction company in Japan. It was featured in an ENR.com article. It was also featured in a booth at world of concrete. Unfortunately I didn't go...

I used revit for my detailing. Like you said there was no good tutorial to use the structural detailing program.

I am looking for a round about number on what people charge for this type of work.
