چکیده انگلیسی
Replacement of whole or part of normal aggregates with Expanded Polystyrene (EPS) beads in the concrete mix is a reliable method to produce Light Weight Concrete (LWC) with considerable advantages. Due to modification effect on mechanical properties of LWC, it is important to examine whether all the assumed hypotheses about conventional concrete also are applicable for LWC structures. Based on an experimental program, this study investigates the effects of specimen size and shape on the compressive and tensile strength of this type of LWC. In this regard, cylinder specimens with 75â¯Ãâ¯150, 100â¯Ãâ¯200 and 150â¯Ãâ¯300â¯mm dimensions and cube specimens with 100 and 150â¯mm dimensions were cast and cured in laboratory conditions. Compressive and tensile strengths were tested after 3, 7, 14, 21, 28, 56 and 91â¯days. The correlation factor between the compressive strength, tensile strength and the shape and size of specimens is evaluated also.
