The recipe I posted on the cement shows how many parts by weight of cement and air lime should be used. But when you stand there and do the cement so you will not have any scales to weigh out the lime and sand on. So to convert from parts by weight to parts by volume as a friend gave me a link where there are a variety of conversion formulas.

I'll sit down and count the weight of the parts for volume and then present it here, so that it easily possible to use the recipes that I previously posted.

Masonry and Plastering service is divided into five strength classes.

Class A = 12 MPa, Class B = 4 MPa, Class C = 1.5 MPa, Class D = 1.0 MPa, Class E = 0.5 MPa.

The further down the alphabet you go, the tougher will use et.

Class A is the hardest and therefore brittle, but it is less porous and therefore less känslit to frost.

Class E is the softest and segast, it is also the use et which was previously used for masonry.

Cement, Masonry cement A, Lime Cement C, Off Murkalk E.

Masonry cement of A, you can mix the use of strength up to Class A, with lime cement C to Class C and so on.

Standard Cement is used for example to mix cement use .

Masonry elements to enter the hydraulic and non hydraulic use .

The hydraulic hardens when it comes into contact with water, ie as soon as the amount coats in contact with water, the reaction to start and you have a begänsad time before use et has hardened.

A non-hydraulic service needs air to cure, this means that they can not harden under water and you can work with it as long as you make sure that it is kept moist. It is less suitable for outdoor use in damp and cold weather.

For traditional masonry of a chimney as used in the past usually non hydraulic lime use , except on Gotland, where their natural lime is of hydraulic type.

Of Finja binders, it's only Off Murkalk E which is not hydraulic.

The difference between cement and concrete is that concrete is the mixing of sand and water in to it then hardens and becomes the concrete.
