- As rightly pointed out by Tarun, you can use foaming Agents or Air Entraining agents to
**decrease**the**density of concrete**. - You can also use EPS beads and Sintered Fly Ash Light Weight Aggregate also.
- But keep in mind this will affect the strength also.

The easiest **way to make concrete** heavier is to cast a larger piece of it. What is the binding material in **cement**? Portland **Cement** itself, a mixture of limestone and clay. Portland is mixed with sand and aggregate to **create concrete**.

**Bulk Density of Concrete** The **bulk density** or unit **weight of concrete** is the mass or **weight** of the **concrete** that required to fill a container of a specified unit volume.

The mechanical properties of **concrete** are highly influenced by its **density**. A denser **concrete** generally provides higher strength and fewer amount of voids and porosity. Smaller the voids in **concrete**, it becomes less permeable to water and soluble elements.

A soils **bulk density** plays a huge role in determining the effectiveness of the soil and the future productivity of a farming operation. **Bulk density** reflects the soil’s ability to function for structural support, water and nutrient and microbial life movement, and soil aeration.

**Bulk density** (g/cm3) = Dry soil weight (g) / Soil volume (cm3) **Bulk density** is usually expressed in megagrams per cubic metre (Mg/m3) but the numerically equivalent units of g/cm3 and t/m3 are also used (1 Mg/m3 = 1 g/cm3 = 1 t/m3) (Cresswell and Hamilton, 2002).

**Bulk density** is an essential parameter for process development and solid dosage manufacturing. It is used in determining the amount of powder that can fit in a space such as a blender or a hopper on a tablet press or capsule filler. It is also used to determine the amount of powder that can be fitted into a capsule.

As a rule of thumb, most rocks have a **bulk density** of 2.

A powder with a wide distribution of particle sizes will have a higher **bulk density** than a powder with a narrower distribution of particle sizes. **Increasing** feed solids generally increases **bulk density**. Feed aeration decreases **bulk density**. Feed suspensions give higher **bulk densities** than feed solutions.

**Bulk unit weight** is a measure of the amount of solid particles plus water per **unit** volume. … Saturated **unit weight** is equal to the **bulk** density when the total voids is filled up with water.

Some inherent factors affect bulk density, such as **soil** texture. Bulk density is also dependent on the **soil** organic matter content and density and arrangement of **soil** minerals (sand, silt, and clay). Generally, rocks have a density of 2.

1. Definition. The **bulk volume** of a powder is the **volume** of the powder divided by the weight, normally expressed in ml/100g powder.

**Calculate** the **volume** delivered by the buret for each measurement. (Subtract the initial buret reading from the final buret reading, as shown in the example.) 10. Use your measured masses to **calculate** the **volume** of water actually delivered by the buret (**true volume**).

**Bulk Unit Weight** / Moist **Unit Weight**

- γ=(G+Se)γw1+e.
- γ=(G+Gw)γw1+e.
- γd=Gγw1+e.
- γsat=(G+e)γw1+e.
- γ′=(G−1)γw1+e.

In math, **volume** is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To **find** the **volume**, you multiply length times width times height, which is 3x1x2, which equals six. So the **volume** of the fish tank is 6 cubic feet.

There are other units **for measuring volume**; cubic inches, cubic feet, cubic yards are all units used **for measuring volume**. Milliliters, liters, gallons are also used especially when **measuring** liquids. We write cubic sizes using a small **3** next to the unit.
