Does your bag look different to the one here.
Prescriptive approach limits on materials.
Or someone familiar with the old website which served well for 20 odd years but a new decade needs a more responsive design and simpler.
Keep dry and store off the ground.
Weight of fine aggregate 790 3 kg m 3.
The addition of 1 8 2 litres of water to a 20kg bag will produce around 9 5 10 litres of concrete.
Very lean mix is not desirable since it does not contain enough finer material to make the concrete cohesive.
The concrete hub app provides a free fast and easy process to create a concrete mix design.
Performance approach desirable characteristics.
Coarser the grading leaner will be mix which can be used.
In lean concrete less quantity of paste is available for providing lubrication per unit surface of aggregate and hence the mobility of aggregate is restricted.
Everything you need to know about dry lean concrete.
Mix design mix design is the process of determining required and specifiable characteristics of a concrete mixture.
Determine quantities of aggregates required to prepare this lean mix concrete.
The type of aggregate influences strongly the aggregate.
Weight of coarse aggregate 1073 33 kg m 3.
Weight of cement 384 8 kg m 3.
The higher the aggregate cement ratio the leaner the concrete.
Dry lean concrete is a mixture in which the amount of cement is less than the amount of liquid that is present in the layers.
Instructions and safety information can be found on the back of the bag.

This makes it ideal as a base layer on which other types of concrete are placed on top.
The app will then display the details of your concrete mix and the quantity of each material required for the specified volume of concrete.
Calculate required quantity of concrete.
For making trial 2 weight of material required will be calculated for 4 no s cube assuming 25 wastage.
