Concrete Grade Expert QA
Which concrete grade for a residential slab?
M20 or M25 grade is ideal for residential slabs. M20 is the standard for domestic buildings, while M25 provides extra structural safety for larger multi-story homes. NavDurga RMC ensures these grades are perfectly balanced for Lucknow's heat and soil conditions.
What is the strength of M25 grade concrete?
M25 concrete provides a compressive strength of 25 MPa at 28 days. Our plant uses high-precision weigh-batching to ensure every delivery hits this target, eliminating the strength inconsistency common in site-mixed concrete.
Nominal Mix vs Design Mix: Which is better?
Design Mix is far superior for structural reliability. While Nominal Mix uses approximate ratios, Design Mix is scientifically engineered to provide optimal density and strength, significantly reducing the risk of cracks in beams and slabs.
