Heavyweight concrete is produced using heavy aggregates and is typically used for radiation shielding, counterweighting, and offshore ballast for pipelines. It can reach densities as high as 400 lbs/ft while maintaining physical properties similar to normal-weight concrete.Jul 3, 2014
What is the density of concrete?
2.4 g/cm³
What is high density of concrete?
Meaning of High Density Concrete: As the name suggests, the density of this concrete varies from 3360 kg/m3 to 3840 kg/m3, whereas the density of normal concrete is of the order of 2400 kg/m3. The density of light weight concrete is about 1900 kg/m3 and that of normal concrete about 2400 kg/m3.
What is a heavyweight aggregate?
Heavyweight aggregates as it can be seen from the name is an aggregate that posses relatively high density and it is fundamental in a situation that high density concrete is necessary. Generally, aggregates with specific gravity of 2400 Kg/m3 and higher are considered to be heavyweight.
How do you make concrete dense?
Obviously, concrete can be made more dense by infusing it with material of greater density than the concrete itself. You could use iron ore instead of limestone aggregate. You could use uranium-bearing sand. You could dump lumps of any extremely dense material into the mix.
How do you make concrete more strong?
To make the concrete stronger, add more cement or less sand. The closer you bring the ratio to an even one-to-one of sand to cement, the stronger the rating becomes.
Where is high density concrete used?
radiation shielding
What is heavyweight structural concrete?
Heavyweight concrete is made from aggregates with a density between 2,080 and 4,485 kilograms per cubic meter (or between 130 and 280 pounds per cubic foot). These aggregates are much less porous and absorbent, and the resulting concrete has a higher mass-to-volume ratio.
What are the advantages of high density concrete?
Advantages of high density MagnaDense concrete Reduced risk for thermal cracking. Space savings. Cost reduction. Faster project completion.
What is the heaviest aggregate?
Heavyweight concrete contains aggregates that are natural or synthetic which typically weigh more than 2,080 kg/m3 and can range up to 4,485 kg/m3. Heavy weight aggregate is most commonly used for radiation shielding, counterweights and other applications where a high mass-to-volume ratio is desired.
What are the three classes of aggregate?
Aggregate serves as a reinforcement to add strength to composite materials such as concrete. Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate.
