FYI
length of fiber used 12mm ,aggregate didn't used and 0.5mm maximum particle size of sand
It depends on the standard you are using. You should check the requirements specified by ASTM-C-1609 and UNE-14488-3 standards. Usually, height and width of the specimen should be greater than 3 times the length of the fiber.
Are you talking about mortar or concrete?, if reinforced concrete that is not possible.
Julian Carrillo. Thanks for your answer, actually the fibre which i used is 12mm so three time length of it less than width and depth.
I was thinking is this small prism enough to install LVDT to check toughness
I think you work on mortar because you do not use aggregates, so you can use the prisms (40 * 40 * 160mm).
Use 3 inch x 4 inch x 16 inch prism for flexural testing. For compression testing you can use a specimen whose minimum dimension should be 4 times the size of larger particle.
I agree Mr. Ahmed Laichaoui. your mixture is mortar or maybe micro-concrete.
and like Mr. Julian Carrillo, It depends on the standard you are using. Frensh standars use 10x10x40 cm3 prism for concrete and 4x4x16 cm3 for mortar. But 7x7x28 cm3 prism is not to flexural testing, it is for concrete shrinkage

Mohammed Al-majidi did you perform the tests mentioned for the mortar?
