✔ Cement may be prescribed as a material with adhesive and cohesive properties, making it capable of bonding mineral fragments into a compact whole.
✔ For construction uses, the word cement is defined as the bonding materials utilized with stones, sand, bricks, building blocks, etc.
✔ The principal components of this type of cement are made of lime, so in construction and civil engineering, we are concerned with calcareous cement.
1. What is the density of Cement?
✔ The density of cement is 1440 kg/m³. This is a bulk density of cement commonly used in civil engineering estimations, numerical, or other field works.
✔ The density of cement varies with the material from which it is prepared.
✔ The density of different cement types is given below:
|Cement Type||Particle Density (kg/m³)||Bulk Density (kg/m³)|
|Ordinary Portland Cement (OPC)||3150||1440|
|Rapid Hardening Cement (RPC)||3150||1280|
|Portland Pozzolana Cement (PPC)||3150||1300|
|Sulphate Resisting Cement (SRC)||3150||1480|
|White Portland Cement||3150||1460|
2. What is the difference between cement’s particle density and bulk density?
|Particle Density||Measurement of mass within a given volume of a substance.||Remains constant||N/A|
|Bulk Density||Measurement of mass within a unit volume of bulk material, accounting for air voids between particles.||Not an intrinsic property||Cement size, specific gravity, grading|
Particle 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.
