The fine aggregate shall be subjected to 5 cycles of the soundness test, which shall have a weighted average loss not higher than 10% and 15% when sodium sulfate and magnesium sulfate are used respectively If the sample of the fine aggregate tested fails, the concrete shall be made with the use of the same fine aggregate and tested for freezing and thawing tests as per ASTM C666/C666MTo complicate matters more, for fine and allin aggregate, where D <= 8mm, the standard requires producers to declare a "typical grading", which, where required, must be within a given Tolerance Category designated according to a set ± value on the D/2 sieve, ie, G TC 10, G TC 20 or G TC NR (no requirement) A typical quarry dust could be designated 0/4 G A 85 G TC 20European Aggregate Sizes Northstone MaterialsThe effect of very fine aggregate on the water requirement and strength evolution of superplasticized concrete was studied The maximum aggregate size was 6 mm, fine aggregate content 0–15% of the total aggregate, binder (OPC and silica) content 80–800 kg m−3, and specific surface area of the finest aggregate material 18–1000 m2 kg−1Effect of very fine aggregate on concrete strength

Fine aggregate gradings with higher fineness modulus values are also cost effective as the coarse particles will reduce the water requirement and therefore the cement required for the concrete mix The fineness modulus is used in concrete mix design to indicate the effects of the fine aggregates on the workability of the mixFor fine aggregate, Slump flow time (T500) has also been evaluated for workability requirement of SCC In the previous investigations, the T500 values of SCC have been found to be increased with the incorporation of CBA as replacement of fine aggregates at lower as well as at higher replacement levels (Jamaluddin et al, 2016; Rafat et al, 2012a, b; Ibrahim et al, 2015) View articleFine Aggregate Replacement an overview |13102018· AIM To findout the silt content in sand (fine aggregates) Apparatus Measuring cylinder Measuring cylinder – 250ml Sand – Specimen Water Salt Solution Procedure The measuring cylinder should be free from moisture and dry Fill the water up to 50 ml with 1% salt solution Then add sand to it until the level reaches 100Silt Content Test of Sand (Fine Aggregates) – we civil
