Sorry.
Concrete is a large part of what I do.

You can run?
I thought it would be harder with cement shoes...

And thus I messed up...
Quote: "Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass. This hardening process continues for years meaning that concrete gets stronger as it gets older. "

Another aficionado?
Not just Portland cement....You can blend with Pulverised Fly Ash (PFA) to give different curing times and strengths. A 70/30 PC/PFA is good for an RC40 mix, self-batched in a volumetric mixer.
Don't get me started on 'Free water' and 'fines'...
God, I'm dull.

Wait...
why did you correct him when he said cement shoes? You could make cement shoes. It might not have the same properties without some aggregate, but for the purposes of weighing someone down to drown them, as pcmechanic planned, it'd be perfectly suitable.
