Microstructure View
Void volume · 5.3%
At W/C 0.45, your concrete has approximately 5.3% void volume. Cement particles are well-packed with controlled spacing for hydration. This is the optimal microstructure for designed strength.
Professional Verdict
“Acceptable mix at upper limit of design. Strength meets specification but durability margin is reduced. Strict curing becomes critical.”

// Key Takeaways
What this means on site
// DO · Order Right
Order pre-designed concrete with verified W/C ratio from Alpha Concrete. Every transit mixer batched to exact mix design. Every batch ticket shows actual W/C delivered.
// DON'T · Never Add Water
Never add water to TM at site. Every liter added per m³ reduces strength by 5–7%. Damage is permanent. No amount of curing will recover lost strength.
// CRITICAL · Why It Matters
On a 100m³ pour, adding just 200L of water reduces strength by 25–30%. Your M30 becomes M22. Insurance won't cover this. Demolition and recast costs ₹5,000/m². Don't gamble.
