1. What is Density of M30 Concrete?

Definition: This calculator determines the density of M30 grade concrete based on its mass and volume.

Purpose: It helps construction professionals and engineers verify concrete quality and specifications.

2. How Does the Calculator Work?

The calculator uses the density formula:

\[ \rho = \frac{m}{V} \]

Where:

\( \rho \) — Density (kg/m³)
\( m \) — Mass (kg)
\( V \) — Volume (m³)

Explanation: The mass of concrete is divided by its volume to determine its density.

3. Importance of Density Calculation

Details: Density is a key quality indicator for concrete. M30 grade concrete typically has a density between 2400–2450 kg/m³.

4. Using the Calculator

Tips: Enter the mass of concrete in kilograms and its volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is M30 concrete?
A: M30 refers to concrete with a compressive strength of 30 MPa after 28 days of curing.

Q2: Why is density important for concrete?
A: Density affects strength, durability, and structural performance of concrete elements.

Q3: What's the typical density range for M30 concrete?
A: Normally between 2400–2450 kg/m³, but can vary based on aggregate type and mix proportions.

Q4: How do I measure concrete mass accurately?
A: Use calibrated scales to weigh a known volume of fresh concrete.

Q5: What if my calculated density is outside the normal range?
A: This may indicate mix problems - check your measurements, aggregate quality, and mix proportions.
