Modelling the evolution of strength and modulus of cementitiously stabilised materials for different curing conditions

The strength and modulus of cementitiously stabilised materials (CSM) are important in pavement design and analysis. This study presents tests and models that can predict the growth of strength and stiffness of CSM under varying conditions. Specimens of nine different mixtures were tested to evaluate the strength gain after curing from 3 to 360 days under 100% relative humidity (RH) at 20°C (the so-called standard condition) using unconfined compressive strength (UCS), modulus of rupture (MOR), and indirect tensile (IDT) strength tests. Additional IDT specimens were prepared from 3 to 56 days of curing at various RH values and temperatures (the so-called variable conditions) for tensile strength and modulus growth. Using the laboratory results, a strength growth model was developed to predict the UCS, MOR, and IDT strength under the standard condition. Also, the IDT strength and modulus models were developed to predict the IDT strength and modulus under the variable conditions.
