The following table provides the standard densities for the most widely used materials in modern construction projects. Material Name Density (kg/m³) Density (lb/ft³) Cement Plain Cement Concrete (P.C.C) Reinforced Cement Concrete (R.C.C) Standard Steel Common Red Brick 1,600 – 1,920 100 – 120 River Sand (Dry) 1,600 – 1,840 100 – 115 Coarse Aggregate 1,500 – 1,750 94 – 110 Timber (Hardwood) Timber (Softwood) 590 – 800 Aluminum Glass Why Material Density Matters in Construction

The density of construction materials—often referred to in engineering as unit weight—is a critical factor in structural design, material estimation, and logistical planning. It represents the mass of a material per unit volume, typically measured in kilograms per cubic meter ( ) or pounds per cubic foot ( Significance in Engineering Accurate density values are essential for: Dead Load Calculation Density of Building Construction Materials: A Complete Guide

Calculate the dead load for your current project using the formula provided. Then, verify your results against the Eurocode or ASTM standard for compliance.

A major mistake beginners make is confusing (mass/volume of the material itself) with Bulk Density (mass/volume including voids). Then, verify your results against the Eurocode or

| Material | Density (kg/m³) | Density (lb/ft³) | Notes | | :--- | :--- | :--- | :--- | | | 7,850 | 490 | Standard for reinforcement bars. | | Reinforced Cement Concrete (RCC) | 2,500 | 156 | Standard weight; varies with aggregate. | | Plain Cement Concrete (PCC) | 2,400 | 150 | Lighter than RCC. | | Bricks (Common) | 1,600 – 1,920 | 100 – 120 | Fly ash bricks are lighter. | | Sand (Dry) | 1,440 – 1,600 | 90 – 100 | Moisture increases weight significantly. | | Aggregate (20mm) | 1,450 – 1,550 | 90 – 97 | Loose state density. | | Cement (OPC) | 1,440 | 90 | Loose; 50kg bag = 0.035 cum. | | Water | 1,000 | 62.4 | The baseline for specific gravity. | | Timber (Teak/Sal) | 650 – 880 | 40 – 55 | Hardwood; softwoods are lighter. | | Glass | 2,500 | 156 | Similar density to concrete. | | Aluminum | 2,700 | 168 | 1/3 the weight of steel. |
