Is there any code which gives the empirical formula for determining flexural strength of MORTAR from its compressive strength ?

15 September 2022 0 9K Report

My sample size is 40 mm x 40 mm , 160 mm in length .

I KNOW for concrete samples , ACI 318 gives such a formula between split tensile strength and compressive strength . But i wanted the formula between flexural strength and compressive strength and that too for MORTARS only. Anyone ?

Is it possible to solve the flow using cell size smaller than the particle size using eulerian multiphase approach?

Hi In eulerian multiphase model, it is assumed that mass and momentum are transferred on a cell-basis. So, if cell size is smaller than particle size, it means that the math is incorrect. But...
