Masonry Review - AG Mech 1

Concrete is difficult to make with local building materials.

Portland cement is made from limestone and clay.

Concrete is fire resistant.

Digging too deeply will require backfilling, which will be less stable.

Compression strength is the ability to withstand heavy weights before it is distorted.

The tensile strength of concrete is higher than its compression strength.

Bleed water is the water that rises to the surface of the concrete as it cures.

You should do the final finish on the concrete while the bleed water is still present.

Floor scrapers are nice to use for cleaning the concrete forms of leftover material.

Strengthening of concrete may continue for months or even years.
