Effect of Specimenís Age on Mechanical Properties of Plastic Concrete Walls in Dam Foundations
Seyyed Hamed Mousavi
According to available information and references, water leakage and internal erosion in bodies and foundations of embankment dams are the main reasons of many problems and failures. To reduce this risk in foundation, plastic cut off walls is one of the most reliable solutions. In this research the effect of specimenís age on the mechanical properties of plastic concrete was studied. This paper summarizes the test results which were conducted in unconfined and triaxial state. Plastic concrete specimens were prepared in the laboratory condition using the materials provided from the Silve dam site. Test results have shown that the time and confining pressure extremely affect the mechanical behaviour of plastic concrete.
Keywords: Cut of wall, Plastic concrete, Elastic Modulus, Compressive strength.
