Cement
Granite
Plaster
Mortar is:
A mix of sand, slaked lime and plaster.
A mix of sand, slaked lime and cement.
A mix of sand, water and plaster.
A mix of sand, water and cement.
Cement is:
A mixture of clay and gypsum rock.(also a small amount of plaster is added)
A mixture of alkali and clay.(also a small amount of plaster is added)
A mixture of limestone and clay.(also a small amount of plaster is added)
A misture of asbestos and clay.(also a small amount of plaster is added)
When water is added to binders and starts a setting process it means that:
The mixture becomes smooth.
The mixture becomes a liquid called flurry.
The mixture becomes hard and resistant.
Which stone binder comes from a gypsum rock?
Cement
Plaster
Mortar
Lime
Binding materials:
React naturally with water, producing a forged reaction which bond particles like sand and gravel.
A homogeneous mixture of plaster and cement which, mixed with water, produce concrete.
Never react with water.
Act like glue when bonding the cement with the concrete.
