pad. We poured the concrete at 9 a.m. with temperatures approximately 55 degrees F at the time of placement. This was the same mix design as the previous day's concrete, but because of the ...

The main materials used for concrete mix design are cement, water, aggregates and admixtures. Cement is the binding agent that reacts with water to form the hardened concrete. Water is the ...

A 14,000 psi (96.5 MPa) design strength mix accounted for 38% of the concrete placed on the project. More than half (58%) of the concrete placed had a design strength of at least 10,000 psi ...

It takes a few minutes to mix up a batch of concrete to its ideal viscosity for pouring and shaping, and this is all under the assumption that you have a cement mixer handy in the first place. The ...

Wavelogix has received a $1 million SBIR grant from the National Science Foundation to develop a solution to scale up production of its novel, patented concrete strength sensors.
