High-strain-rate behavior of hydrated cement pastes
AbstractThe stress-strain behavior of cement pastes, hydrated for 28 days, over a range of strain rates (from almost static to 103 sec−1) has been investigated. At low strain rates (<250 sec−1) the ultimate stress increases with increase in strain rate, whereas at high rates (>250 sec−1) it reaches a limiting value. The stress behavior appears to correlate with the porosity of the system. Examination of the fracture surface suggests that fracture occurs preferentially through the C-S-H phase of the hydrated cement.
