<![CDATA[The structural engineering field is advancing rapidly. Fly Ash contains silica, similar to cement. This study examines the use of Fly Ash waste as a cement substitute in concrete production, with polycarboxylate added. Fly Ash was used at 15% and 30% with polycarboxylate at 1% and 2%. The target compressive strength was 25 MPa, with normal concrete mix. Tests focused on compressive strength in polycarboxylate variations. Another set of concrete mixes substituted 15% and 30% cement with Fly Ash, adding polycarboxylate at 1% and 2% of cement content. Results showed a compressive strength of 25.38 MPa for normal concrete and 25.78 MPa and 25.94 MPa for 1% and 2% polycarboxylate mixes, respectively. With 15% and 30% Fly Ash plus 1% polycarboxylate, compressive strength increased by an average of 0.635 MPa; with 2% polycarboxylate, it averaged 5.25 MPa. Similarly, for tensile strength, 1% polycarboxylate with 15% and 30% Fly Ash achieved an average of 5.45 MPa, while 2% polycarboxylate reached 18.63 MPa with the same Fly Ash percentages.]]>
