Understanding the Density of Concrete • Aggregate Research

As for concrete itself, the density of concrete of normal weight is about 2,400 kg per cubic meter, or 145 lbs. per cubic foot. The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used.

Density of Cement, Sand and Aggregate, Bulk Density of

The approximate value of bulk density for aggregate usually used for normal-weight concrete varies between 1200-1750 Kg/m 3 or 75 to 110 lb/ft 3. Relative Density or Specific Gravity of Aggregate Aggregate Contains both permeable and impermeable pores.

Density of Cement Sand and Aggregate Cement Density

Dec 06, 2020· The approximate apparent density of the aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg / m 3 (75-110 lb / ft 3). Here, the standard test method for determining the apparent density of aggregates is presented in the ASTM C 29 (AASHTO T 19) standard.

Concrete Density an overview ScienceDirect Topics

The density achieved depends on the type of aggregate used. Generally, the increased concrete density is achieved using barite, magnetite, or hematite aggregates. When using barite aggregate, the density of concrete is about 3400 kg/m 3, which is 45% higher than that of ordinary concrete; with magnetite the density is equal to 3500 kg/m 3 —by 50% higher than that of normal concrete

How Bulk Density and Voids of Aggregates affect Concrete?

Aug 24, 2020· Bulk Density of Aggregates. Aggregates is the main component of concrete and accounts for 60 to 70% of volume and 80% of weight of concrete due to which aggregates are considered filler for concrete. Variety of aggregates

High Density Concrete: Types and Properties Concrete

4. The modulus of elasticity and poisson’s ratio of high density concrete and normal concrete are approximately the same. 5. Shrinkage of high density concrete is about 1/4 to 1/3 of the normal concrete. 6. Thermal conductivity, diffusivity etc. of high strength concrete is considerably lower than corresponding values for normal aggregate

Materials For High Density Concrete Production

To achieve the required concrete density to absorb the radiation a combination of high-density aggregates steel shot (fine aggregate) and hematite iron-ore (coarse aggregate) was used. The use of high density aggregates increased the cost for 40 Mpa concrete from approximately R370.00 to R7 600.00 per cubic metre of concrete

Aggregate classification by density

Yes. Those used to make normal-density concrete are called normal-density aggregates. Those for low-density concrete (historically known as “lightweight” concrete) that have an air-dried density at 28 days usually in the range of 1440 to 1850 kg/m 3 (90 to 115 lb/ft 3), are called low-density aggregates.
