PROCESS DETERMINING MODULUS OF ELASTICITY OF FILLING AGENT Russian patent published in 1998 - IPC

FIELD: test of construction materials, evaluation of elastic properties ( modulus of elasticity ) of filling agents. SUBSTANCE: process determining modulus of elasticity of filling agent lies in manufacture of samples carrying standard and tested large-size filling agents with different absolute concentrations, modulus of elasticity of solution component is determined by results of tests of concrete samples with standard filling agent and modulus of elasticity of tested filling agent is found from formula , where E_o, E_зэ, E_зn, E_p are correspondingly moduli of elasticity of concrete, standard filling agent, tested filling agent, solution component, MPa; ϕ₁,ϕ₂ are absolute volume concentrations of standard and tested filling agent. EFFECT: diminished labor input and errors in determination of modulus of elasticity of filling agent. 2 tbl
