Table 4 Cost calculation of a single conventional sandcrete brick against proposed SDA/BLA sandcrete brick.
From: Development of sustainable sandcrete bricks using industrial and agricultural waste
Material | Price (USD) | Benefits | |
|---|---|---|---|
Cement brick | Cement | 0.01 | Faster setting and hardening, allowing quicker construction OPC is widely available and meets industry standards, ensuring consistent quality Less preparation time |
Sand | 0.003 | ||
Water | 0.00 | ||
Labour Cost | 0.06 | ||
Total | 0.073 | ||
Proposed agro-industrial sandcrete brick | Cement | 0.002 | Partial replacement of cement powder with Sawdust Ash (SDA) and Banana Leaf Ash (BLA) minimizes cement consumption, leading to potential cost savings Lower carbon footprint in producing the brick Lighter in weight making it convenient for transportation |
