Abstract

The increasing need for efficient, durable, and environmentally friendly construction materials has driven innovation in the development of lightweight bricks, especially Cellular Lightweight Concrete (CLC). However, in areas with high humidity, lightweight bricks are susceptible to excessive water absorption, which can accelerate the deterioration of building structures. To overcome this, additional materials are needed that can increase durability while reducing the level of water absorption in lightweight bricks. This study aims to determine the effect of adding Nano Silica on the compressive strength and water absorption of lightweight bricks. The method used is quantitative with experimental techniques. This study used variations of Nano Silica of 0%, 3%, 6%, and 9% with a 28-day test. The results showed that the addition of 3% nano silica produced the highest compressive strength, which was 8.85 MPa, compared to normal lightweight bricks which only reached 5.50 MPa. However, at concentrations of 6% and 9%, the compressive strength decreased to 7.35 MPa and 4.15 MPa. Meanwhile, the results of the water absorption test also showed a significant decrease, from 19.29% in normal bricks to 9.74% in the 9% nano-silica variation. Therefore, it can be concluded that nano-silica can effectively increase durability and reduce water absorption in lightweight bricks, with special attention to the optimal concentration to maintain mechanical quality.
