Properties of concrete - Wikipedia

Additional samples may be field cured (non-standard) for the purpose of early 'stripping' strengths, that is, form removal, evaluation of curing, etc. but the standard cured cylinders comprise acceptance criteria. Concrete tests can measure the "plastic" (unhydrated) properties of concrete …

Fire and Concrete Structures - cement.org

Concrete containing lightweight aggregates and carbonate aggregates retain most of their compressive strength up to about 1200 oF. Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and therefore generally provides increased fire resistance.

The 28-Day Myth - National Precast Concrete Association

Oct 28, 2013· Concrete usually reaches 75% of the 28-day strength at seven days. If your concrete is not reaching the proper 28-day strength, I would troubleshoot each step of the process to determine why. Here are example questions you can ask: Q: Is the mix design correct? A high water-cement ratio will result in a concrete with reduced strength.

Beam Bearing on Concrete - B G Structural Engineering

Beam Bearing on Concrete. Last Revised: 06/16/2011. A bearing plate takes the reaction of a steel beam and distributes that force over a larger area that is made of a material that is not as strong as steel. The action is essentially the same as a footing that distributes a large load to softer soil.
