eurocode 2 part 1-1: design of concrete structures 3.1.3 (3) variation of the modulus of elasticity with time can be estimated by: ecm(t) = ( fcm(t) / fcm) 0,3 ecm. (3.5) where: ecm(t) is the secant modulus of elasticity of concrete at an age of t days. ecm. is the secant modulus of elasticity of concrete at 28 days.
melted and recrystallized basalt has demonstrated promising behavior with regards of its use in manufacturing, as reported in the literature.this paper presents the results of an experimental study on the determination of the modulus of elasticity of molten and recrystallized basalt by the method of resistive electrical tensometry and to
first the basalt is melted at a temperature of 1,400 °c (2550 °f). the molten rock is then extruded through small nozzles for the production of filaments of basalt fibers. the high modulus of elasticity of the product results in an excellent tensile strength, which is more than twice the tensile strength of steel.
the modulus of elasticity of basalt reinforcement is lower than that of steel, but higher than that of fiberglass. the specific gravity of composite reinforcement is 4 times less than that of steel, which leads to a decrease in the weight of the frame, the cost of handling and transport costs.

basalt rock possesses certain qualities similar to thermoplastics and metals, i.e., it melts when heated to specific temperatures (1100–1300 °c) and can be drawn into flexible fibers, a process similar to manufacture of s-2 and e-glass fibers.
modulus of elasticity of high strength concrete using iraqi aggregate with a wide range of 41 to 83.3 mpa has been studied and by analyzing 69 tests from the available literature. an empirical equation has been proposed for prediction of modulus elasticity presents the local aggregate in iraq. the predicted values are compared with

elastic modulus. these two explanations are confirmed when comparing frc mixtures with the same fiber content: the mixtures with longer fibers have lower elastic modulus.22 there have been many new elastic modulus equations developed specifically for frc.18,20,23-26 however, because the elastic modulus is influenced by various parameters, the
benefits of basalt fiber: in addition, fiberglass fiber has a significantly lower tensile strength, a lower modulus of elasticity, and the poisson’s ratio indicates that it is a more fragile material than basalt fiber and steel. polypropylene fiber.
