“…The works of [5], [6], [7], [8], [9], [10], [11], [12], [13] and [14] investigated normal-weight concretes with compressive strengths in the common structural range of 30 to 100 MPa. Those concretes were mainly obtained with natural aggregates and type I cement.…”

The standard European building specifications, grouped in a 9-volume Eurocode, describes different approaches for determining the properties of commonly used building materials such as steel, aluminium, concrete, ... The American Concrete Institute (ACI) also offers different reports concerning concrete structures (ACI 318R), lightweight concrete (ACI 213R) and its long-term mechanical behavior (ACI 209R). Those reports, used as building codes, are also applicable when the material respects certain scope criteria. All materials which do not meet the scope criteria of Eurocode 2 or ACI reports because of their composition, properties values, or application cannot be used in the design of structures with those building codes. Regarding cement-based materials, concretes and mortars which compressive strength is lower than the minima might not be useful for structures, however they present an interesting potential for applications such as infrastructure materials, low-solicited slabs, ... When designing a structure/infrastructure made of those materials, the accuracy of any formula offered by those building codes should be checked before being used. This work shows the comparison between experimental measurements and the predictive formulas of the engineering properties (compressive and tensile strength, modulus of elasticity). The results show that the addition of specific aggregates which present low stiffness and strength modifies the relation between those engineering properties, which makes its estimation impossible without considering its unit weight.

“…In addition to evaluating the dynamic modulus of elasticity, ultrasound pulse velocity can be correlated with the compressive strength. This relatively simple test is commonly applied in assessing the performance of hardened concrete [7,[9][10][11][12] and can be successfully used in CSM characterization [13].…”

“…Thus, the measurement and accuracy of determined elastic properties are questionable. Secondly, direct evaluation of the static modulus of elasticity is a complicated and time-consuming procedure [7]. It is why researchers and practitioners rely on the much easily determined dynamic modulus of elasticity, which is most often defined by the non-destructive method of ultrasonic pulse velocity.…”

“…These inconsistencies mean the accuracy of the measured elastic properties is questionable. Second, directly evaluating the static modulus of elasticity is complicated and timeconsuming (Panesar and Shindman 2011). These complications, as shown in our measurements, occur because cement-stabilised materials usually contain an aggregate of gravel or crushed rock.…”

“…Because of these changes, the accuracy of this technique for measuring elastic properties is questionable. Second, directly evaluating the static modulus of elasticity is complicated and time-consuming (Panesar and Shindman 2011). Because of these issues, in this study, the dynamic modulus was determined and used to predict the static modulus.…”

In this study, we evaluated the elastic and mechanical properties of a new type of cement-stabilised material made with steel slag, varying the content of cement and steel slag. To study the elastic properties of these mixes, we measured their density, compressive strength and ultrasound pulse velocity at curing ages of 7, 28 and 90 days. The aggregate type and curing age greatly affected the elastic properties and varied much depending on the cement content. The Poisson's ratio chosen in analyses had little influence on the dynamic modulus. Various expressions given by building codes were used to predict the elastic properties of the mixtures. These codes generated very different values of the static modulus of elasticity, making most of them unsuitable for predicting the elastic properties of cement-stabilised materials. Using our experimental data, we provide the best combination of existing equations to predict elastic properties, and we conclude that measuring the ultrasound pulse velocity is a suitable way to predict the mechanic and elastic properties of cement-stabilised materials.
