## What is ASTM 29?

Scope. 1.1 This test method covers the determination of bulk density (“unit weight”) of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.]

## What is the ASTM standard used for determining the bulk density unit weight and voids of aggregates?

standard ASTM C29 for

WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM C29 for Bulk Density (“Unit Weight”) and Voids in Aggregate.

**What is loose unit weight of aggregate?**

Loose Unit Weight of Aggregate Loose Unit Weight is the weight of a known volume of unconsolidated aggregate. Use the shoveling procedure for loose bulk density detailed in AASHTO T 19, Bulk Density and Voids in Aggregate.

### What is the unit weight of aggregate?

The standard density of aggregate which is used in concrete making is about 1200-1750 kg/m3.

### What is C 138 test under the standard a STM test method?

What C138 test under the Standard ASTM test method? Explanation: According to Standard ASTM test methods to evaluate field-placed concrete C138 test is for Test Method for Unit Weight, Yield, and Air Content (Gravimetric) of Concrete.

**What is ASTM C31?**

ASTM C31. This practice provides standardized requirements for making, curing, protecting, and transporting concrete test specimens under field conditions.

#### What is bulk density formula?

Bulk Density Formula Bulk density is obtained by dividing the dry mass of soil by its total volume. The bulk density formula or bulk density equation is: γ=mdvt γ = m d v t , where md refers to the mass of the dry soil and vt refers to the volume of the dry soil. γ is the bulk density of dry soil.

#### How do you calculate bulk density of aggregate?

If the volume is unit then, Bulk Density= Mass. Unit in kg/m3 or lb/ft3. In this definition, the volume is that contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3).

**How do you calculate the weight of an aggregate?**

Calculate the unit weight of the aggregate by multiplying the net mass of the aggregate by the factor found as described in Section 4 of this test method.

## How is unit weight calculated?

Simply divided the total weight by the total volume to find the weight per single unit of volume.

## What is the weight of 1m3 aggregate?

Ans. 1550 Kgs is weight of 1 cubic metre (m3) of 20 mm aggregate.

**How is aggregate calculated in CFT?**

1 cft stone ( aggregate) weight in kg:-Density of aggregate (stone) is vary from 1420 Kg/m3 to 1680 Kg/m3,consider density of aggregate (stone) 1600 Kg/m3, it means 1m3 stone weight is 1600kgs,1m3 = 35.3147 cft, so 35.3147 cft aggregate (stone) is equal to 1600 kg, then 1 CFT stone (aggregate) weight in kg 1600/35.3147 …
