Infrastructure development is a driver of innovation in structural engineering. Innovation is really needed in structural engineering so that developments in structural planning occur. One innovation arises because of something big. In this research, structural innovation was carried out in the field of concrete by analyzing the effect of silica sand content on the compressive strength of K-250 concrete. Silica sand is used as a concrete mixture with several compositions, namely 0%, 30%, 80% and 100%. This research process involved testing concrete quality for 14 and 28 days for each variation in silica sand composition. The research results showed that the concrete quality inspection had met the required standards, namely 21 MPa. For each concrete composition with a mixture of silica sand, the average compressive strength values obtained were 23.3 MPa for 0% composition, 22.25 MPa for 30% composition, 22.61 MPa for 80% composition 23,55 MPa, and 25, 01 MPa for 100% composition. From these results, it can be seen that the use of silica sand as a mixture in K-250 concrete has a positive influence on increasing the compressive strength of the concrete. The highest quality concrete is found in a silica sand mixture with a composition of 100%, namely 26.03 MPa. This shows that silica sand has great potential in improving the quality of concrete, especially in terms of compressive strength. Thus, the innovation of using silica sand in the K-250 concrete mixture can be an effective alternative for improving concrete quality. Further research is recommended to explore various variations in composition and type of silica sand, as well as their effect on various other concrete parameters. Apart from that, research can also pay attention to external factors such as weather and environmental conditions that may influence the final result of the concrete. This innovation is expected to make a significant contribution to building stronger and more durable infrastructure, as well as providing more economical and efficient solutions in the long term.
