What is specific gravity of building materials?
Specific gravity is the ratio of mass of given substance to the mass of water at 4oC for the equal volumes. Specific gravity of some materials is listed below….Specific Gravity of Building Materials.
| Material | Specific gravity |
|---|---|
| Steel | 7.82 |
| Cast iron | 7.20 |
| Aluminum | 2.72 |
What is the density of construction materials?
Density of construction materials are its mass per unit volume of materials. It is expressed in kg/m3 or lb/ft3 and shows compactness of building material. Density is also called as unit weight of substance. It is represented by symbol called row (p).
What is the specific gravity of concrete?
The specific gravity of aggregates is commonly ranging from 2.6 to 3.0. Specific gravity is used to separate deleterious particles, lighter than other particles, from good aggregates. It is used in calculating the solid volume of aggregates in concrete mix.
What is unit weight of construction materials?
Unit Weight of Construction Materials – Cement, Steel, Concrete, Sand, RCC, etc.
| SL. NO. | MATERIAL | THEORETICAL UNIT WEIGHT (kg/m3) |
|---|---|---|
| 1. | Cement | 1440 kg/m3 |
| 2. | Steel | 7850 kg/m3 |
| 3. | Sand | |
| (a) Dry | 1600 kg/m3 |
What is the specific gravity of steel?

What is the specific gravity of brick?
| Product | Specific Gravity – SG – |
|---|---|
| Brick, common red | 1.75 |
| Brick, fire clay (firebrick) | 2.4 |
| Brick, hard | 2.0 |

What is density of RCC?
The density of RCC is 2500 kg/m3 or 25 KN/m3, as specified by the standards.
What is the density of steel and concrete?
Steel is about 3.25 times as dense as plain concrete, so if 1% by volume is rebar replacing concrete density increases 2.25%. While 1% by volume would be above average for typical mesh-reinforced composite slabs, it would be well below average for reinforced concrete superstructure generally.
What is the specific gravity of bricks?
What is the density of RCC?
What is unit weight of RCC and PCC?
Unit weight of PCC = 2400kg/m^3. Unit weight of RCC = 2500kg/m^3.
What is the specific gravity of wood?
where Mmax is maximum moisture content and Gw is the specific gravity of wood substance, equal to approximately 1.54 (Skaar 1988).
How do you calculate specific gravity?
Specific gravity, also known as the relative density, is calculated by dividing the density of a substance by a reference density. The most common reference density is pure water, making one common definition of specific gravity the ratio of a substance’s density to that of pure water.
What is ideal specific gravity?
OG= Original gravity (your initial reading)
What is an example of specific gravity?
Specific gravity is a concept that shows up in a variety of industrial applications, particularly as it relates to fluid dynamics. For example, if you’ve ever taken your car in for service and the mechanic showed you how small plastic balls floated in your transmission fluid, you’ve seen specific gravity in action.
What is the specific gravity of minerals?
The specific gravity of a mineral determines how heavy it is by its relative weight to water. The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water.
