Type III Type III cement is chemically almost identical to Type I, though it has a lesser curing time, which means it hardens faster. It is also ground finer, and contains a higher amount of C 3 S, both of which promote the rapid setting of concrete. This type imparts strength faster than Type I, typically in less than a weeks time, though its final 28-day strength may be equal, if not lesser.
Other than concrete blocks, which other company is making bricks in Zambia. It’s time someone set up a brick-making enterprise so people can begin using bricks again like back in the old days.
Aggregate to cement proportions should be about 3 parts aggregate to 1 part cement by volume for field/hand mixed concrete. Only enough water should be added to afford workability and eliminate voids in the mix. The less water you use, the higher the strength of the cured concrete.

Among the ancient Assyrians and Babylonians, the bonding substance most often used was clay. The Egyptians developed a substance more closely resembling modern concrete by using lime and gypsum as binders. Lime (calcium oxide), derived from limestone, chalk, or (where available) oyster shells, continued to be the primary pozzolanic, or cement-forming, agent until the early 1800s.
In the picture below, we use clay to create a small containment area on the model to test for cure inhibition against the model material. Two-Part Block Molds.
