Описание: What is the difference between M20 and M25 concrete mix ratios? 🏗️
In construction, concrete grades are critical for strength & durability.
✅ M20 = 1:1.5:3 (Cement:Sand:Aggregate)
✅ M25 = 1:1:2 (Cement:Sand:Aggregate)
Knowing the right mix ensures long-lasting foundations, slabs, and beams. This short video breaks it down simply for students, site engineers, architects, and contractors.
