Ferrocement, a versatile building material, is becoming increasingly popular in structural and architectural applications. It is suitable for high degrees of prefabrication due to its durability, weather resistance, and relatively low cost. Additionally, there is the possibility to achieve considerable improvements in various properties of these thin structures by using some alternates. A study has been made on the behavior of ferrocement trough shaped panels (FCTSP) under static load using clay silica for partial replacement of cement and manufacturing sand for partial replacement of river sand. First, the strength characteristics of mortar cubes were determined by varying the percentage of cement with silica sand (0%, 5%, 10%, 15%, 20% and 25%). Incorporating the optimum percentage of clay silica replacement, a study on the flexural behavior of trough shaped panels reinforced with skeletal steel and wire mesh layers by replacing fine aggregates with manufacturing sand and varying the percentage of replacement was found. According to the findings, panels made with a combination of 10% clay silica sand (CSS) replaced for cement mix and 50% manufacturing sand (MS) replaced for the fine aggregate used in FCTSP showed better results in mechanical properties and microstructural bond behavior.
