Development of high-performance heavy density …
To achieve the high-performance concrete (HPC- grade M60), All concrete mixes had a constant water/cement ratio of 0.35, cement content of 450 kg/m 3 and sand-to-total aggregate ratio of 40%. Concrete density has been measured in the case of fresh and hardened. The hardened concrete mixes were tested for compressive strength at 7, 28 and 90 days.

High Density Concrete - Concrete Future
James proposed the high density magnetite aggregate and the initial concrete mix design. Several finishing and pumping trials were undertaken in collaboration with Watpac (the Principal Contractor) and Concrite (the concrete supplier) to confirm the compatibility of the mix using conventional pumping and finishing methods as the mix was initially more cohesive than typical concrete. Thermal ...

The Effect of Aggregate Properties on Concrete
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete. Although aggregate is considered inert filler, it is a necessary component that defines the concrete's thermal and elastic properties ...

Weighing In on High-Density Concrete - NPCA
Typical concrete density is around 150 lbs/cu ft. Lightweight concrete can weigh as little as 95 lbs/cu ft. High-density concretes range from 190 to 260 lbs/cu ft. Even higher densities (≥ 350 lbs/cu ft) can be attained but are rare. Aggregates: the most critical component The key to high-density concrete …

High Density Concretes for Radiation …
In contrast with conventional concrete weighing around 150 pounds per cubic foot, high-density concretes normally weigh from 200 to 250 pounds per cubic foot. Among the natural aggregates most commonly used are barite, magnetite, limonite, geothite, and ilmenite. These can be used for the lower and medium weight ranges. For densities over 250 pounds per cubic foot, expensive aggregates …

When using only MagnaDense as a high density aggregate, concrete with densities up to 4.0 t/m 3 is achievable. Mixing MagnaDense into concrete with other aggregates allows you to produce even heavyweight concrete with densities up to 5.0 t/m 3. With the correct mix design, high-density concrete can still achieve good workability.
