Which are the three types of cements?

• A. Rockwool, One Coat, Finishing Cement
• B. Portland, Epoxy, Latex
• C. Sand, Cement, Water
• D. Asphalt, Bitumen, Tar

Answer: (A)

Cement types in construction refer to different binders used to bond materials together and provide the right balance of strength, adhesion, and durability. The common categories you’ll encounter are Portland cement (the standard binder for most concrete and mortar), epoxy cement (a resin-modified binder chosen for very strong, chemical-resistant bonds), and latex cement (cement modified with latex polymers to improve flexibility and adhesiveness). These three represent distinct cementitious binders with different performance, so they’re the best trio to describe “types of cement.”

Other items listed don’t fit as cement types: rockwool is an insulation material; one coat and finishing cement refer to plaster mixes rather than cement types; sand, cement, and water are ingredients of a mix rather than different cement categories; and asphalt, bitumen, and tar are bituminous materials, not cement.
