	Cement is primarily produced by slaking quicklime. This involves adding the quicklime to water to convert it from CaO to CaOH. In this state it can be used as a pickling lime, as cement, plaster, mortar or as a food additive. Though there are many forms of cement, most involve taking limestone, aragonite or seashells, heating them above 900c to remove the organics, then slaking the resultant quicklime.

			== Materials needed ==

			* 80% '''Limestone (calcium carbonate)'''
			* 15-20% '''[[Clay]] or Shale'''
			* 0-5% '''Rust powder ([[Iron\|iron oxide]])'''
			* '''Gypsum (CaSO₄)''' (5% of the total mass of previous mixture)
			* A '''rotary [[kiln]]'''

			== Crafting instructions ==

			# Grind all ingredients into a fine powder using a mortar and pestle or ball mill. Mix thoroughly to get a uniform raw meal.
			# Heat mixture in a crucible or kiln to 1450°C (2642°F) for about 30 minutes, forming pellets called clinker.
			# Cool rapidly to preserve mineral phases (drop into dry sand or on a steel plate).
			# Grind clinker into a fine powder.
			# Add gypsum (CaSO₄·2H₂O) equal to 5% by weight and grind again to make true cement.

			== Uses ==
			Cement has a strong compressive strength and can be poured to fit any mold. this versatility has led to widespread use in construction including roads, buildings, bridges, and more.

	'''Cement''' is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind [[sand]] and [[gravel]] (aggregate) together. Cement mixed with fine aggregate produces [[mortar]] for masonry, or with sand and gravel, produces [[concrete]]. Concrete is the most widely used material in existence and is behind only [[water]] as the planet's most-consumed resource.
