EVALUATION OF THE PERFORMANCE OF SUSTAINABLE MODIFIED POLYMER CONCRETE MADE FROM VARIOUS WASTE MATERIALS

Due to its superior performance over traditional materials, polymer concrete has emerged as a new engineering material in the current context.The main focus of this study was the design and manufacture of polyester polymer concrete (PC) from various recycled materials for use in various building applications.Four different types of recycled aggregate from easily accessible crushed building materials were employed: waste glass (WG), crushed mortar (CM), crushed clay bricks (CB), and crushed concrete (CC).Sustainable modified polymer concrete (SMPC) specimens were made using a conventional casting method and various replacements for normal sand, such as crushed concrete, mortar, clay bricks, and waste glass (10, 20, 30, and 40 volume percent).The mechanical properties of SMPC with and without recycled aggregate were tested for compressive, tensile, and flexural strength.The findings showed that adding (10%, 20%, 30%, and 40%) of (CC, CM, CB, and WG) as a partial substitute for natural fine aggregate improves the mechanical properties (compressive strength, direct tensile strength, and flexural strength) of SMPC.In comparison to other waste materials, the results of using crushed concrete were the best and highest.Similar to reference PC and SMPC with recycled fine aggregate, the rate of strength evolution with age is roughly the same.This research also looked into how the curing temperature affected the SMPC's compressive strength characteristics.The 20, 40, and 60 C curing temperature ranges were taken into consideration.The findings demonstrate that the compressive strength of PC, both with and without recycled fine aggregate, is significantly impacted by a curing temperature above 20 C.
