1. Prepare sand equivalent test specimens from the passing No. 4 sieve portion of the material to be tested after it has been processed according to the procedures prescribed in California Test 201, except that reclaimed aggregate containing traces of asphalt or asphalt concrete shall not be oven dried at temperatures greater than 100˚F.

Fine aggregates and sands have the potential to contain levels of deleterious minerals that can have a negative impact on concrete properties. The most frequently employed method in New Zealand to ensure suitability of fine aggregates and sands for concrete is the sand equivalent test. This test has been reviewed, along with the other two readily

Then, concrete test samples were prepared using these aggregates, and the properties of the fresh and hardened concrete were determined. The results show that although all the samples were found to be suitable for use as fine aggregate in high-strength concrete production, natural sands that contained smectite-type clays have poor aggregate ...

Sand Equivalent Tex-203-F 80 Fineness Modulus Tex-402-A 2.3 to 3.1 1. Only when air-entrained concrete is specified. Provide fine aggregate or combinations of aggregates conforming to the gradation requirements shown in Table 6 when tested in accordance with Tex-401-A unless otherwise specified. Table 6 Fine Aggregate Gradation Chart (Grade 1)

The suitability of crushed stone dust waste as a fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. Two basic mixes were chosen for natural sand to achieve M25 and M30 grade concrete. The equivalent mixes were obtained by replacing natural sand by stone dust partially and fully.
