Differences between hydraulic and non hydraulic cement?
Hydraulic cements are material that set and harden after being combined with water as a result of chemical reaction with the mixing water, and that after hardening retain strength and stability even under water. Non-hydraulic cement include such materials such as plaster of paris, which must be kept dry in order to gain strength .
How do you make hydraulic cement?
How to make hydraulic cement.Stir dry in a wheel barrel.50 lb bag portland80 lb bag masonry cement50 lb bag play sand or silica sand15 lb Plaster of Paris or Molding PlasterNote: Be sure all the plaster is displaced evenly throughout the barrel.Scoop out the amount you need and just add water.Work quickly to mix water with hydraulic materialStir immediately!Fast-setting - sets in 3-5 minutesPerformance - instantly stops seepagePre-blended - just add waterAuthor, T.

Why does repaired fractured leg look weak after removing plaster?
when we use our muscle in workout it gets hypertrophied(increase in size) and when wedon't use the muscle it gets atrophied(decrease in size).so when fracture happened we don't use the muscles of that part for long time so its look weak after removing plaster of Paris

Which mineral makes plaster harden?
First you need to recognize that "plaster" is not a singularly defined material; it is a family of quite different materials that harden by different mechanisms. The three most common plasters are (1) Plaster of Paris, (2) Lime Plaster, and (3) Cement Plaster.(1) Plaster of Paris is CaSO4.H2O, a partially-dehydrated form of Gypsum, which is a hydrated Calcium Sulfate crystal CaSO4.2H2O. When Plaster of Paris is mixed with water, it re-hydrates and turns back into Gypsum, which then hardens into a material similar to mortar or concrete but considerably softer. Water is the material that makes Plaster of Paris harden.(2) Limestone When exposed to atmosphere the Calcium hydroxide turns back to limestone, causing the plaster to set.(3) Cement Plaster is a mixture of Portland Cement powder, sand or other filler, water, and either Plaster of Paris or Lime Plaster. Due to the great variety of minerals that makeup Portland Cement and Cement Plaster, the hardening is a complex process that cannot be ascribed to the action of any one of the ingredients.
What is the difference between white cement and plaster of Paris?
There are only slight chemical and physical differences between gray portland cement and white portland cement. These differences are due to raw material differences and sometimes, though not always, slight differences in manufacturing. The goal is to minimize the oxides (particularly iron and manganese) that impart the grayish color normally associated with portland cement. Souce:PCA (portland Cement Association)

Why is plaster of Paris called plaster of Paris?
Gypsum plaster (plaster of Paris) ( CaSO4·½H2O ) A large gypsum deposit at Montmartre in Paris led gypsum plaster to be commonly known as "plaster of Paris"
