Type s contains 2 parts portland cement, 1 part hydrated lime and 9 parts sand. type n is described as a general purpose mortar mix and can be used in above grade, exterior and interior loadbearing installations. type n is made of 1 part portland cement, 1 part lime and 6 parts sand.
Ratios then are key to a consistent mortar mix so it is important to be accurate! the most common mix for blockwork is: 41, that is four parts sand to one part cement but there are variations. for instance if you are using a softer brick then 51 or 611(six.
The preferable mortar mix ratio for pointing is 1part mortar and either 4 or 5 parts building sand. the ratio will vary depending on what exactly is being pointed. for bricklaying, you will usually want a 1:4 ratio with plasticiser added to the mixture. for above dpc airtech blocks, 5 parts building sand and 1part cement is preferable.
Estimation of water, cement & sand quantity for cement mortar. let us assume a standard quantity of 1m 3 cement mortar and a mix proportion of cm 1:6 (1 part cement & 6 parts sand). the quantity can calculated in two ways, one is by weight and the other by volume. let us consider the volume method for the calculation of cement & sand quantity.

Using Lime In Mortar – Cape Brick
Lime mortar has a 60 greater bonding strength to sand cement only mortars. this helps to reduce moisture penetration through the mortar as well as prevent mortar waste occurring when mortar falls off masonry, causing waste. typically builders use up to 3 times the amount of mortar originally estimated as a result of waste.
Lime sand mortar is the traditional and often preferred way of working. mixed on site with cement and water, lime sand mortars creamy consistency provides greater yields and bond strength. tarmac lime sand mortars are factory produced lime sand mortars for use in bricklaying, rendering, plastering or paving applications.
