Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...
High density concrete mix design. 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.

Dec 30, 2015· An industrial Portland cement type CEM II 42.5 N from Algeria, with a density of 3100 kg/m 3 and an average compressive strength at 28 days of about 42.5 and 62.5 MPa, was used for all concrete mixtures. Three limestone crushed NA fractions (coarse NG 3/8, NG 8/15 and fine NS 0/3) coming from MontGorno region and three other RAP fractions (coarse RG 4/10, RG 10/14 and fine .
Mar 01, 2011· The natural and recycled aggregates were characterized. Concrete mix designs with 25%, 50%, 75% and 100% of aggregates substitution were formulated. The performances of the "recycled aggregates" concrete were measured through tests of density, air content, workability and compressive and tensile strength. 2. Experimental program 2.1.
Concrete and aggregate used in your construction projects has to meet strict regulations and quality standards. As these standards are often compulsory, concrete and aggregate testing by an independent third-party is necessary to help assure compliance.

Sep 03, 2017· Approximately 75% of the volume of concrete is occupied by aggregates, so quality of aggregates plays an important role in determining properties of concrete. Aggregates are chemically inert, solid bodies held together by the cement. Aggregates come in various shapes, sizes, and materials ranging from fine particles of sand to large, coarse rocks.
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.
