Cracks developing in reinforced concrete columns shortly after casting are among the most frequently reported and concerning construction site issues. These early-age cracks—typically caused by plastic shrinkage, thermal stresses, poor curing practices, or improper mix proportions—are not merely cosmetic. They…
Concrete is the backbone of any construction project—whether it’s laying a foundation, building columns, or finishing a slab. But what happens when you’re working at a site where there’s no access to a concrete mixer? This is where knowing how…
Concrete grades (M5 to M40) specify the 28-day compressive strength (in MPa) and use different mix proportions of cement, sand, and aggregates. Nominal mixes (fixed cement: sand: aggregate ratios) are prescribed for Grades M5 up to M20, while design mixes…
