Concrete Cracking

Concrete is only as strong as the foundation it's on. If the ground has some sort of natural movement, big or small then you would expect the concrete to perform in the same way.

What Is Concrete Slump?

Jul 17, 2017 · Slump is a measurement of the workability or consistency of concrete. In other words, it measures how easy the concrete is to push, mold and smooth out. Accordingly, its slump rating indicates what construction application the concrete is good for. The higher the slump, the more workable the concrete.

The Anti-Industrial Revolution

Even if smog were a risk to human life, we must remember that life in nature, without technology, is wholesale death. As far as the role of government is concerned, there are laws — some of them passed in the nineteenth century — prohibiting certain kinds of pollution, such as the dumping of industrial wastes into rivers.

Use air en- trained cement. When order-ing ready mix, specify a 6 sack mix with a maximum slump of 2” in lieu of the 6 gallons of water limitation.


Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4”) slump is very common with normal weight concrete and is a good average slump for pumping.
