  • Aggregates testing equipment, Controls

    Mineral aggregates are used in all fields of the construction industry to produce bituminous misture, concrete, mortars to be used in structures, fill materials, railway ballast etc. For this reason we have given particular attention to all testing methods. The EN Standards have grouped all tests on aggregates in five main subjects:

  • EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

    The effects of aggregate type, size, and content on the behavior of normal and highstrength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:Y. in.), and

  • Sieve analysis Wikipedia

    Sieve analysis has, in general, been used for decades to monitor material quality based on particle size. For coarse material, sizes that range down to #100 mesh (150μm), a sieve analysis and particle size distribution is accurate and consistent. However, for material that is finer than 100 mesh, dry sieving can be significantly less accurate.

  • Gradation of Coarse Aggregates

    Proper gradation of coarse aggregates is one of the most important factors in producing workable concrete. Proper gradation ensures that a sample of aggregates contains all standard fractions of aggregate in required proportion such that the sample contains minimum voids.

  • Sieve analysis Wikipedia

    A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

    On Aggregate Grading is good concrete performance dependent on meeting grading limits? Specifying concrete mixtures with wellgraded (WG) combined aggregates can be controversial. Advoes14 argue that such mixtures have optimized packing and minimal voids and therefore minimize the cementitious paste required for a given workability.
