Passage One
One of the primary materials used in the construction of buildings and roads is cement
a powder made primarily from limestone and clad.
Even though the ancient Egyptians and Romans used a kind of cement,it was not until 1824 that an English bricklayer develope
a cement strong enough for modern roads and buildings.
While experimenting in his kitchen
the bricklayer found that a mixture of limestone and clad
that had been heated together formed a hard
stone like chunk as it cooler
When this substance was ground into a find powder it could be stored indefinitely.
When the powder was mixed with water
it made an excellent quality of cement that quickly hardened in sunlight or even under water.
With only a few variations
this is how cement is made today.
