Dry Lean Concrete Mix Proportions
Aggregate to cement ratio and moisture content for the dlc to be manufactured with ppc so that the requirement.
Dry lean concrete mix proportions. By measuring the cement stone and sand you will have a consistent concrete mix throughout your entire project. This is lower than specified maximum w c ratio value of 0 50. 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. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device.
Concrete mix ratios are the proportions of concrete components such as cement sand aggregates and water. 1 curve d figure shown in the end found to be 0 42. The numbers denote the ratio of all in stone and sand. 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. The mix shall be proportioned with a maximum aggregate cement ratio of 15. Dry lean concrete is an important part of the modern rigid floor. The concrete mix proportions i e.
However building codes provides nominal and standard concrete mix ratios for various construction works based on experience and testing. These mix ratios are decided based on type of construction and mix designs. Mix proportion of dry lean concrete. 1 22 2014 6 basic concrete mix design materials pounds of material s g.
Dry lean semi dry mix cement bound material consisting of cement 4 20mm stone graded sand and minimal water. The less water you use to mix the concrete somewhat dry but workable the stronger the concrete mix. 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.

The mix design for dlc is not similar to the conventional concrete mix. Dry lean semi dry mix cement bound material consisting of cement 4 20mm stone graded sand and minimal water. 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.
