Fine aggregate angular detector

The tester applied to determination of natural sand, artificial sand, stone, etc. used in the fine aggregate surface roughness in order to assess the fine aggregate particles of the edges and corners, surface structure, fine aggregate prediction of asphalt mixtures internal friction angle and anti-deformation properties of the flow and mixing cement concrete workability impact. The apparatus in line with the Ministry of Communications JTJ-2000 standards. This product is based on "JTJ058-2000 Highway Engineering Test aggregate of order" in the "T0344-2000 fine aggregate angular tester of" rules of design and manufacture.
