I began the experimental stage of this project by carrying out basic tests to understand the properties of rice husk ash. These included observing its appearance, texture, and smell. The rice husk ash appeared fine and powdery, felt dry to the touch, and did not have a strong smell, which suggested that it could be handled easily and safely for further testing.

I also conducted a pH test to identify its chemical nature. For this experiment, I added 50 grams of rice husk ash to a container and mixed it with 250 millilitres of distilled water. After mixing the solution thoroughly, I tested it using a pH indicator. The results showed that the rice husk ash was alkaline in nature, which is an important property for materials used in construction and supports its potential use as a partial replacement for cement.
