The process of making fly ash bricks
Collection and Use of Fly Ash
• Fly ash, a byproduct of coal combustion, is mixed with cement, sand, and water.
• This mixture forms the raw material for brick production.
Molding and Shaping
• The fly ash mixture is poured into molds and pressed to form bricks.
• This process ensures uniformity in the final product.
Curing and Hardening Process
• Bricks are cured by exposing them to steam or water for several days.
Factors Affecting Fly Ash Brick Price in Pakistan
• Quality and Grade: Higher-grade bricks from premium fly ash and cement are more durable and offer better performance, leading to higher prices.
• Transportation and Logistics: Distance between manufacturing and construction sites and mode of transport can add significant costs, especially in remote areas.
• Regional Variations in Prices: Prices can vary significantly across different regions in Pakistan due to local demand and supply dynamics.
• Market Demand and Seasonal Variations: Peak construction seasons often lead to increased prices, while off-peak times or adverse weather conditions may result in more competitive pricing.
