Properties of plaster of Paris.....❓❓❓☺️ |
|
Answer» Thanks mr.avi.... of Paris is easy to spread and level.It is fire resistant highly.It forms a thick surface to resist normal knocks after drying.It expands very slightly on the setting.It does not cause cracking of surfaces. It gives a decorative interior finish. It mixes up easily with water. It is a white powder. When mixed with water (1/3 of its mass), it evolves heat and quickly sets to a hard porous mass within 5 to 15 minutes. During setting, a slight expansion (about 1%) in volume occurs so that it fills the mould completely and takes a sharp impression. Thanks sanket..... 1) It is fire resistant highly.2) It forms a thick surface to resist normal knocks after drying.3) It expands very slightly on the setting |
