Step#4 Drying Process

After the pressing and molding phase, the bricks undergo the drying process to reduce moisture content and enhance their structural integrity. Here are the specific actions involved in this phase:

• Initial Air Drying: Place the molded bricks in an open area with good air circulation to initiate the drying process. Regularly turn the bricks to ensure even exposure to air. This step is essential for reducing the initial moisture content.
• Controlled Environment Drying: Transfer the bricks to a controlled environment with precise humidity and temperature control to prevent cracks and ensure consistent drying, with the duration tailored to the brick’s requirements.
• Duration Management: Monitor the drying time carefully, which may vary from several days to weeks depending on brick thickness and external conditions. Frequently monitor the drying process and adjust the time as needed to achieve the best state of readiness for bricks.
• Moisture Monitoring: Throughout the drying process, continually measure the moisture content of the bricks using appropriate moisture meters to ensure the bricks have reached the ideal dryness level. Adjust the drying process or remove bricks not meeting the moisture standards.

Step#5 Curing the Bricks

Building on the foundation laid by the drying process, curing the bricks is a vital stage in enhancing their strength and durability. Here are the key procedures:

• Submerge Bricks in Water Tanks: Soak the dried bricks in water tanks to initiate the hydration process. Maintain the water level and monitor its temperature to ensure the curing conditions remain at their best. Regular checks are conducted to ensure the quality of the water used.
• Manage Curing Time: The bricks remain submerged for a predetermined period, typically two to three weeks. This duration is vital for the complete hydration of the cement components within the bricks. Adjust the duration based on the brick composition and environmental factors.
• Regulate Temperature and Humidity: Keep a constant check on the temperature and humidity levels in the curing area. Adjust these parameters to maintain a stable curing environment. This regulation helps prevent thermal stress and guarantees uniformity in the curing process.
• Gradual Drying Post-Curing: After the curing time, remove the bricks and allow them to dry slowly to prevent cracking and to maintain the strength gained during curing. Monitor the bricks throughout this phase to ensure even drying and readiness for further processing.

Step#6 Quality Testing

Transitioning from the meticulous curing process, the next crucial phase is quality testing, ensuring each brick meets the strict standards required for construction use. Here are the critical assessments performed:

• Dimensional Accuracy: Each brick is measured for its length, width, and height to ensure they adhere to specified dimensions. Precision in size is vital for the consistency and stability of brickwork. Tools like calipers and measuring tapes are commonly used in this assessment.
• Compression Testing: This test evaluates a brick’s load-bearing capacity by gradually applying pressure with a compression machine until it breaks, indicating its suitability for construction. Tabrick employs such testing methods, ensuring the highest standard of interlocking brick quality and performance.
