Feb 01, 1955· Discusses crushing and handling of the magnetite iron ore, which was used as the aggregate for a dense shielding concrete, and the physical properties and costs of magnetite ore concrete are compared to those of other concretes. The mix
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.. ASTM Standards. C33 Specification for Concrete Aggregates. C125 Terminology Relating to Concrete and Concrete Aggregates. C127 Test Method for Relative Density (Specific Gravity) and Absorption of Coarse Aggregate
The density achieved will depend on the type of aggregate used. Typically using barites the density will be in the region of 3,500kg/m 3, which is 45% greater than that of normal concrete, while with magnetite the density will be 3,900kg/m 3, or 60% greater than normal concrete.
While concrete is a blend of Portland cement, sand and gravel, cement is the dry, powdered substance that is mixed with sand, gravel and water to become a binder for concrete. Mixing sand, gravel, water and cement in the right proportion is essential to producing durable, high-quality concrete.
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural
Quality Counts. Make sure that your concrete producer purchases good-quality aggregate as verified by regular aggregate test results in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates." A history of good performance of a local aggregate also provides an indication of how well the material performs in service.
Natural heavyweight aggregate. MagnaDense is a natural aggregate manufactured from the iron oxide Magnetite. With its high specific gravity MagnaDense is used as a coarse material to produce heavyweight concrete. As a result, you will get high density concrete that has more weight and your project will require less volume.
Oct 24, 2015· An additional heavyweight concrete mixture was also produced using magnetite as a natural mineral heavyweight aggregate. In all concrete mixes produced, water/cement ratio, cement content, and the maximum aggregate size of the aggregates used were kept constant.
Similarly, the compressive strength of concrete prepared with magnetic water increased 10-23% more than that of the tap water samples. In particular, the best increase in compressive strength of concrete is achieved when the magnetic strength of water is of 0.8 and 1.2 T.
High density concrete gives a composite shield for both neutron and gamma radiation. High density aggregates are the key ingredient in high density concrete. The most common aggregates used to achieve the required densities are Hematite (Fe2O3), Ilmenite (FeO TiO2), Magnetite (Fe3O4) and Steel Aggregate.

Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete. • Aggregates in any particular mix of concrete are selected for their durability, strength, workability and ability to receive finishes.
Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
Rust Coloured Stains on the surface of Exposed Aggregate Concrete What is causing the Rust Coloured Stains There are a multitude of causes that can result in Rust Coloured Stains on the surface of concrete. This document deals specifically with rust coloured stains created by “Ironstone” on the surface of Exposed Aggregate Concrete.
Select the pea gravel or other decorative stone as the aggregate for the concrete. The type of aggregate you choose will have a strong impact on the resulting look of your surface. Varying from 1/8-inch to 3/4-inch in size, pea gravel is a smooth, round stone that comes in a variety of natural colors.
