Bending and compressive behaviors of a new cement composite

The Laboratoire Central des Ponts et Chaussees (LCPC) has recently developed and patented a new cement composite, the CEIATEC(multiscale), which is stress hardening in tension and has a very high uniaxial tensile strength, more than 20 MPa. This paper is about the determination of the compressive and bending behaviors of the CEMTECmultiscale used in the frame of ribbed slabs. The principal results obtained are the following: the characteristic modulus of rupture is equal to 42 MPa for the slab function; the characteristic modulus of rupture is equal to 48 MPa for the rib function; the ultimate tensile strain is around 5 10(-3); the characteristic strength and ultimate strain in compression are equal to 205 MPa and 4 10(-3), respectively; and the Young modulus is equal to 55 GPa and the Poisson coefficient is equal to .21.
