By measuring the cement stone and sand you will have a consistent concrete mix throughout your entire project. However building codes provides nominal and standard concrete mix ratios for various construction works based on experience and testing.

Extra dry lean concrete is. Unlike conventional concrete mixes the water to cement ratio is not the criteria for dlc mix design but it is the optimum moisture content omc to ensure full compaction of concrete under rolling. Dry lean concrete is an important part of the modern rigid floor. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device.

Dry lean semi dry mix cement bound material consisting of cement 4 20mm stone graded sand and minimal water. It is smooth concrete with a large proportion of aggregate in relation to cement than conventional concrete and is generally used as a base sub base for hard paving. Dry lean semi dry mix cement bound material consisting of cement 4 20mm stone graded sand and minimal water. 1 curve d figure shown in the end found to be 0 42.

The current practices of the construction of cement concrete road for highways in india require a layer of dry lean concrete dlc as a base course over which pavement quality concrete slabs rest. The numbers denote the ratio of all in stone and sand. Dlc or dry lean concrete is cement concrete with low slump value to be laid for rigid pavement over sub base and rolled compacted by mechanical means. The mix design for dlc is not similar to the conventional concrete mix.

The mix shall be proportioned with a maximum aggregate cement ratio of 15. Concrete mix ratios are the proportions of concrete components such as cement sand aggregates and water. These mix ratios are decided based on type of construction and mix designs.
