Ispitivanje očvrslog betona — Deo 13: Određivanje sekantnog modula elastičnosti pri pritisku

English title

Testing hardened concrete - Part 13: Determination of secant modulus of elasticity in compression

Serbian scope

Ovim dokumentom se utvrđuje metoda za određivanje sekantnog modula elastičnosti pri pritisku očvrslog betona na ispitnim uzorcima koji mogu biti izliveni ili izvađeni iz konstrukcije. Metodom ispitivanja se mogu odrediti dva sekantna modula elastičnosti: — početni modul EC,0, izmeren pri prvom opterećivanju i — stabilizovani modul EC,S, izmeren nakon tri ciklusa opterećivanja. Date su dve različite metode ispitivanja. Prva metoda (metoda A) je za za određivanje oba modula, početnog i sstabilizovanog, dok je druga metoda (metoda B) samo za određivanje stabilizovanog modula.

English scope

This document specifies the method for the determination of the secant modulus of elasticity in compression of hardened concrete on test specimens which can be cast or taken from a structure. The test method allows the determination of two secant moduli of elasticity: the initial modulus, EC,0 measured at first loading and the stabilized modulus, EC,S measured after three loading cycles. Two different test methods are given. The first (Method A) is for determination of both initial and stabilized moduli, the second (Method B) is for determination of stabilized modulus only.
