Types of Cements and Construction Materials

What are the differences between Magnesium phosphate cement, Cold-mix asphalt, and Portland cement?

Which materials are used in each of these construction materials?

Answer:

Magnesium phosphate cement is a quick-hardening cement made from magnesium oxide and a soluble phosphate. Cold-mix asphalt is a type of asphaltic concrete made by combining oil and fine aggregate. Portland cement, commonly used in building, comprises mainly of calcium, silica, alumina, and iron.

Explanation: Magnesium phosphate cement is a type of cement made from a reaction of magnesium oxide and a soluble phosphate such as ammonium phosphate. It is often used in repair work due to its ability to harden quickly.

Cold-mix asphalt is an asphaltic concrete that is made by combining oil and fine aggregate. This mix is then spread and compacted at a temperature that is lower than that used in a hot mix asphalt procedure.

Portland cement is a type of cement commonly used in buildings. It is a complex product derived from limestone, shale, and clay, heated in a kiln and then ground. The key ingredients in Portland cement are calcium, silica, alumina, and iron.
