Plaster Mix

Plaster Mix

Plaster Mix

(OP)

Hi,

To calculate proportions by weight of a plaster mix 1 : 4 by volume we need to multiply the dry densities of cement & sand with the volume proportions. How much cubic of fresh plaster mix does it give you after mixing with water say W/C = 0.45 ?

Absolute vol method of calculating the proportions will lead to erreneous proportions by vol.

We need a fresh plaster mix of 1 cubic meter batched by weight and proportioned by volume in 1:4 ratio with W/C = 0.45. Your comments plz...  

RE: Plaster Mix

Is this an interior or exterior plaster and are you using portland cement and sand?

RE: Plaster Mix

Make it easy. Mix three trial batches and measure the volume. average them. If you want a better number mix three more. Hint. They don't need to be 1 cubic yard batches.
