1. What is Density of M25 Concrete?

Definition: Density is the mass per unit volume of M25 grade concrete, typically around 2400 kg/m³.

Purpose: Understanding concrete density helps in structural design, material estimation, and quality control.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

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

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

3. Importance of Concrete Density

Details: Density affects structural strength, durability, and load-bearing capacity. M25 concrete typically has a density of ~2400 kg/m³.

4. Using the Calculator

Tips: Enter the mass of concrete in kg and volume in m³. Both values must be > 0. The default value shown is typical for M25 grade.

5. Frequently Asked Questions (FAQ)

Q1: What is M25 concrete?
A: M25 refers to concrete with a compressive strength of 25 MPa after 28 days of curing.

Q2: Why is density important?
A: Density affects dead load calculations, structural design, and material quantity estimation.

Q3: What factors affect concrete density?
A: Aggregate type, cement content, water-cement ratio, and air content all influence density.

Q4: How does M25 density compare to other grades?
A: Density is similar across grades (2300-2500 kg/m³) as it depends more on aggregates than strength.

Q5: When would measured density differ from 2400 kg/m³?
A: With lightweight aggregates, excessive air entrainment, or improper mixing proportions.
