Plaster of Paris expands slightly when it sets due to the hydration process involved in its chemical reaction. This expansion is typically around 0.1% to 0.5% and occurs as the gypsum crystals form and interlock during the hardening phase. However, it is essential to control the mixing water and environmental conditions to minimize excessive expansion, which can lead to cracking or warping in the final product. Overall, while it expands slightly, Plaster of Paris is primarily known for its dimensional stability once fully cured.
