Understanding the Density of Concrete • Aggregate

2009-11-26  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.

2021-9-4  The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3). Here, the Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19). Relative Density of Aggregate

Concrete Density - an overview ScienceDirect Topics

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 and with hematite aggregate the density is approximately 3600 kg/m 3 —53% higher than normal concrete.

Aggregate classification by density

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.

Ronez - Aggregate

Aggregate.

2013-6-1  Recycled concrete aggregates (RCA) have been produced since 2009 as a result of the extensive CD activities in Qatar. It is estimated that around 20,000 tons of CD are produced daily (∼7.3 million tons/year); half of which are converted daily to RCA.

Advantages of low-density aggregate

There are also low-density, nonstructural concretes having an oven-dry density of 800 kg/m 3 (50 lb/ft 3) or less. These concretes achieve their low density by incorporating low-density aggregates, air entrainment, or preformed foam.

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 and with ...

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 in 1996.

The effects of limestone aggregate on concrete properties

2021-8-2  In the 70s, river rocks were mainly used as aggregate in Japan. Since then, the ratio of aggregate taken from land and mountain has increased gradually in order to preserve the natural environ-ments of rivers. Recently, the ratio of crushed stones is increasing [3]. The ratio of limestone as aggregate in the concrete in 1974 was only 1.3%.
