What are the Advantages of Dry Lean Concrete? What is DLC? DLC (Dry Lean Concrete) is a crucial component of modern stiff pavement. It is plain concrete with a higher aggregate-to-cement ratio than ordinary concrete, and it is commonly used as a stiff pavement base/sub-base. It works well on a flat surface that is uneven or unclean. It's frequently utilized to produce a tight seal between bricks or other elements of infrastructure. What is the grade of dry lean concrete?

What is the minimum curing period required for dry lean concrete?
Curing will begin as soon as the lean concrete surface has been compacted. Curing is accomplished by covering the surface with gunny bags/hessian and keeping it damp for 7 days by sprinkling water.
Dry Lean Concrete Mixing Ratio The DLC mix is not comparable to traditional concrete mixes in terms of design. Unlike traditional concrete mixtures, the water/cement ratio is not a design requirement for the DLC mixture; instead, the optimal moisture content (OMC) is used to ensure total compaction of the concrete under lamination. Because it becomes stuck in the roll drums, the mixture should not be too wet. As a result, determining the optimal moisture content for proper compaction and mixing ratios, i.e. the aggregate/cement ratio, is critical for achieving the required compaction and compressive strength of the concrete.
Concrete Strength of DLC In 7 days, the average compressive strength of a DLC mixture should be at least 10 MPa. The major acceptance criterion for dry lean concrete mixtures is the cube's compressive strength after 7 days.
