Introduction to the production process of baking-free block bricks

 

1. Batching: the batching of various raw materials is mainly determined according to the strength grade of small blocks, and the strength of small blocks is also related to the hollow rate of small blocks. After the mix proportion is determined, all raw materials are measured by weight. Whether the measurement is accurate or not will directly affect the workability of the mixture and thus the performance of small blocks. In particular, the moisture content of sand and stone shall be tested frequently to ensure the accuracy of mix proportion.

 

2. Concrete mixing: sand, cement and stone shall be fed in sequence for mixing, and water shall be added for mixing after dry mixing. If admixtures are added, they can be added after wet mixing with water. Dry mixing and wet mixing are used to fully mix the mixture evenly. Uneven mixing will reduce the workability of the mixture and the strength of small blocks. Too long mixing time will affect the production efficiency of the mixer. The forced mixer shall be selected for the concrete mixer, and the slump of the concrete mixture shall be controlled to 0, but the block surface shall be slightly wet and dense during forming.

 

3. Forming: the small concrete hollow block shall be formed by vibrating and pressurized brick machine. The block brick machine produced in China has been continuously improved and improved, and has been able to produce high-quality small concrete hollow blocks.

 

4. Maintenance: generally, natural maintenance is adopted. The product shall be watered more than 3 times a day. The product shall be kept wet. The product can be delivered after continuous watering for about 7 days and natural maintenance for 28 days. Steam curing can also be used to shorten the curing time, and the products can leave the factory as soon as possible.

 

5. Stacking and inspection of finished products: small blocks shall be stacked by specification and grade, with marks set on the stacking. The stacking site must be flat, and the stacking height shall not exceed 1.6m. Appropriate channels shall be maintained between the stacking, and rain proof and drainage measures shall be taken.
