Laying refractory bricks, also known as brickwork or bricklaying, requires careful planning and proper techniques to ensure a durable and effective installation. Here are general steps to follow when laying refractory bricks:
1. Preparation: Gather all the necessary tools and materials, including refractory bricks, refractory mortar, trowels, brushes, water, and safety equipment like gloves and goggles. Ensure that the surface where the bricks will be laid is clean, stable, and free from any debris.
2. Mortar Mixing: Prepare the refractory mortar according to the manufacturer's instructions. The mortar should have the right consistency for easy application while providing sufficient bonding strength.
3. Layout and Marking: Determine the desired layout of the bricks based on the specific project requirements. Use a pencil or marker to mark the positions where the bricks will be placed. Consider factors such as expansion joints, thermal expansion, and any design considerations for optimal performance.
4. Brick Placement: Apply a layer of refractory mortar onto the prepared surface using a trowel. Place the first brick carefully into position, pressing it firmly into the mortar. Ensure it is level and aligned with the marked guidelines.
5. Joint Formation: Leave a small gap, typically around 3-5mm, between bricks for expansion and accommodate mortar. Use a pointed trowel or jointing tool to form straight and consistent joints between the bricks.
6. Proceed with Additional Bricks: Repeat the process of applying mortar, placing bricks, and forming joints one by one. Maintain uniform spacing and alignment throughout the installation. Check periodically with a spirit level to ensure the vertical and horizontal alignment of the bricks.
7. Cutting and Shaping: When required, cut or shape bricks to fit the desired dimensions or accommodate corners, curves, or irregularities in the structure. Use appropriate cutting tools, such as a masonry saw or chisel, to achieve precise fits.
8. Cleanup and Finishing: Remove excess mortar or any smears on the brick surfaces using a wire brush or a damp cloth. Allow the mortar to cure and set according to the manufacturer's instructions, providing the necessary time for drying or firing.
It's crucial to follow safety guidelines and wear appropriate protective gear while working with refractory materials. It's also advisable to consult professional guidelines or seek expert assistance when undertaking complex or large-scale installations to ensure a successful and reliable brickwork arrangement.
