Mix ratio of sand and cement screed for floor varies based on the intended use of the screed.
Floor screed weight.
It may be applied onto either a solid in situ concrete ground floor slab or onto a precast concrete floor unit.
All laterlite screeds can be mixed by traditional means in a cement mixer or mixed and pumped in a pneumatic floor screed conveyor machinery for easy transport to the required floor.
Latermix cem mini is semi fluid and is the most versatile and lightweight of these screeds weighing only 600 kg m 3 and gives the greatest load reduction.
Cube m cement weighs about 1300 kg cubic meters.
So for 1 square.
In bags usually 50 kg.
Simply multiply by thethickness to get a weight 22kn m 22000n m 1 newton mass x acceleration kg g g is acceleration dueto gravity on earth g is.
When the thickness of the screed 10 mm the weight of one square meter can reach 20 lbs.
Limitations on imposed dead loads will determine the density of the lwc to be used.
M area you need 1300 0 5 650 kg of cement and 1600 2 3200 kg of sand.
M of sand 1600 kg.
Added to that cement type grade of aggregate and the method of storage of screed material influence the mix ratio to a certain extent.
Therefore a suitable type of cement shall be selected and sand needs to.
This screed volume calculator will work out the approximate quantity of screed that you would need to order based on the measurements that you supply.
Given the fact that the minimum thickness may not be less than 30 mm this thickness allows to avoid cracking of the screed and its crumbling and considering the weight of the insulation and the finishing coating one square meter of floor will weigh about 70 75 lbs.
We would always recommend a little extra to allow for waste and small changes in depth.
At 100 square meters.
The bulk density of screed is 22kn m.
Input your projects dimensions into the screed volume calculator below and you have your screed volumes.
M screed thickness of 5 cm will need 6 5 kg of cement.
A floor screed is usually a cementitious material made from a 1 3 or 1 4 5 ratio of cement to sharp sand.
