The proportioning of the concrete mix structure need to end in an economical and sensible combination of supplies to make concrete with the Qualities preferred for its intended use, for instance workability, strength, durability and physical appearance.
Following the Roman Empire, the use of burned lime and pozzolana was tremendously diminished. Low kiln temperatures while in the burning of lime, lack of pozzolana, and poor mixing all contributed to a drop in the standard of concrete and mortar. From the 11th century, the enhanced utilization of stone in church and castle construction resulted in a heightened desire for mortar.
