ANALISIS SIFAT MEKANIK MORTAR DENGAN PENAMBAHAN NANOSILIKA HASIL SINTESIS FLY ASH METODE HIDROTERMAL SEBAGAI SUBSTITUSI SEMEN DENGAN VARIASI SUHU CURING

Nanosilica is a nano-sized material (1–100 nm) that can be used as a partial substitute for cement to improve the mechanical properties of mortar. This study aims to analyze the effect of nanosilica synthesized by fly ash using the hydrothermal method and variations in curing temperature on the compressive strength of mortar. Nanosilica was used at 12% with curing temperatures of 40°C, 60°C, and 80°C. The method used was a laboratory experiment with mortar test specimens measuring 5×5×5 cm. Tests included slump flow, setting time, and compressive strength at the ages of 3, 7, 14, and 28 days. The results showed that increasing the curing temperature accelerated the development of compressive strength at an early age. At 3 days, 12.15 MPa, 14.12 MPa, and 14.78 MPa were obtained, increasing to 16.05 MPa, 18.37 MPa, and 19.13 MPa at 7 days. At 14 days, it was 20.36 MPa, 22.38 MPa, and 22.23 MPa, and at 28 days, 23.41 MPa, 25.66 MPa, and 24.33 MPa for temperatures of 40°C, 60°C, and 80°C, respectively. A temperature of 60°C provided the optimum compressive strength at 28 days, whereas 80°C was more dominant at early ages. In general, the addition of nanosilica increased the compressive strength of mortar through microstructural improvements and pozzolanic reactions, with 60°C as the optimal temperature.
