What doesn’t kill us makes us stronger, said philosopher Friedrich Nietzsche. Who would have thought that a similar notion might apply to materials? To explain, we have to start with something almost as strange. “The reason concrete is so strong is because it’s so weak,” sa...
Water- Water is needed to chemically react with the cement (hydration) and too provide workability with the concrete. The amount of water in the mix in pounds compared with the amount of cement is called the water/cement ratio. The lower the w/c ratio, the stronger the concrete. (higher...
The main job of a bonding agent is to make the bond between the old and new concrete surface stronger. The cement in a concrete mix doesn’t have anything that naturally makes it stick together. So, when new concrete is poured over an existing layer, the two layers don’t tend to ...
Concrete has high compressive strength, meaning it can hold a lot of weight without getting crushed. This makes it an excellent material for building and road foundations. But concrete gets bad marks for tensile strength. If it bends, it cracks. This is no bueno for bridges, beams and column...

Exit interviews can only be valuable if you utilize the feedback to make concrete changes. After identifying the areas of concern, the next step involves developing action plans to address the issues raised. The action plans should be realistic, specific, and measurable. For instance, if feedbac...
A version of this result (with a slightly different formulation of ) appears in this paper of Motohashi and Pintz, and in the paper of Zhang, Theorem 5 is proven for the concrete values and . We will supply a self-contained proof of Theorem 5 below the fold, the constants upon those ...
In such cases, the Siegel zero becomes a very concrete manifestation of the parity barrier, rather than a means to avoid it. (There is a tiny chance that there may be some sort of “repulsion” phenomenon in which having no semiprimes in for one value of somehow generates semiprimes in ...
This question may sound silly, but the thickness of your concrete slabs is crucial to your project. The optimal thickness is dependent on the size and use of the building. Thicker slabs will be stronger but will require more support. On the other hand, if the slabs are too thin, they ma...
