Recent development in construction industry requires new materials with higher mechanical properties. Therefore, it is necessary to develop grout materials using materials at nano scale. The purpose of this study is to determine the optimal content of nanosilica in grout material. Initial mix was given code G0. Then the nanosilica was added with 1% content (code G1), 2% content (G2), 3% (G3), and finally 5% nanosilica content (G5). Compressive strength tests were carried out when the grout was aged 1, 3, 7, and 28 days. Whereas flexural strength test was carried out at 28 days. The result finding showed that the optimal nanosilica content was at 3% (G3), significantly improved compressive strength 24.6%, tensile strength 20.9% and flexural strength 25.6%. The contribution of this research is to introduce nanogrout as an advanced material, to overcome the challenges of increasingly complex construction work in the future.
