Normal density, also known as particle density of aggregate, **commonly ranges between 2400 to 2900 kg/m³.**

Aggregate Type | Particle Density (kg/m³) | Bulk Density (kg/m³) | Relative Density |

Normal | 2400-2900 | 1500-1800 | 2.4-2.9 |

Lightweight | 900-2200 | 500-1200 | 0.9-2.2 |

Heavyweight | 2500-4000 | 1500-2000 | 2.5-4.0 |

**1. What is the difference between Particle Density and Bulk Density?**

Property | Definition | Constancy | Influencing Factors |

Density | Measurement of mass within a given volume of a substance. | Remains constant regardless of size/shape. | N/A |

Bulk Density | Measurement of mass within a unit volume of bulk material, accounting for air voids between particles. | It’s not an intrinsic property. | Aggregate size, shape, specific gravity, grading. |

Density is the measurement of mass within a given volume of a substance. **This property remains constant regardless of the size or shape of the sample**, making it a distinctive characteristic of the material.

Conversely, **bulk density** refers to measuring mass within a unit volume of a bulk material, considering the air voids between particles. This is not an intrinsic property, as it **can vary depending on the degree of compaction of the material**.

The **bulk density of a material is influenced mainly by the aggregates’ size, shape, specific gravity, and grading** rather than the container where it is stored. Therefore, these factors play a crucial role in determining the bulk density of a material.

**2. What is the Density of Aggregate? **

The density of normal aggregate ranges from **2400 to 2900 kg/m³. **

**( Note: Density is also known as particle density. )**

Aggregate Type | Particle Density (kg/m³) |
---|---|

Normal | 2400-2900 |

Lightweight | 900-2200 |

Heavyweight | 2500-4000 |

**3. What is the Bulk Density of Aggregate? **

The bulk density of normal aggregate ranges from **1500 to 1800 kg/m³. **

Aggregate Type | Bulk Density (kg/m³) |

Normal | 1500-1800 |

Lightweight | 500-1200 |

Heavyweight | 1500-2000 |

**4. What is the Relative Density of Aggregate? **

The **relative density** of normal aggregate ranges from **2.4 to 2.9. **

Aggregate Type | Relative Density |
---|---|

Normal | 2.4-2.9 |

Lightweight | 0.9-2.2 |

Heavyweight | 2.5-4.0 |
