influence Shenyang gas filling block There are three main factors of hardness: the proportion of raw materials, the importance of post curing, and the influence of construction methods.

1. The proportion of raw materials in the proportion of aerated brick raw materials Aerator block The hardness factor is mainly reflected in the water cement ratio. Under normal conditions, the hardness of aerated brick and water cement is inversely proportional. At the time of construction, the mixing operation is carried out after the share is determined. When mixing, attention shall be paid to the water cement mixing ratio to improve the quality and ensure the accuracy of the proportion. During field operation, attention should be paid to the measurement of gravel, especially the water content of gravel. The reasons for transportation and climate change usually indicate the amount of income and expenditure. In the face of this situation, it is necessary to test again and determine whether the proportion is correct, adjust the amount to ensure accuracy, and then strengthen the hardness.

2. Post maintenance is very important. The qualified aerated brick can be manufactured after the aerated brick production line passes the precise process. In order to ensure hardness, maintenance is necessary. The operation must be carried out in strict accordance with the maintenance principle, either wet or save water, and all processes must be carried out in accordance with the rules of the system. All maintenance methods are actually to ensure the quality of aerated bricks. In addition, the factors affecting the hardness of aerated blocks are the mix proportion of concrete raw materials such as fly ash, sand, admixtures, cement, sand, stone, water, etc. Construction and curing also have some effects on concrete. The key factors affecting the quality of concrete are the factors that must be manipulated during this period: cement strength, sand fineness, slurry content, water content and stone needle content. Larger material diameter, fineness of fly ash, mix ratio (water cement ratio) accuracy, mixing and compatibility during pouring, concrete mixture gas content, vibration strength and vibration time, maintaining temperature and humidity.

3. Influence of construction methods, including mixing, transportation, pouring, vibration, etc. All links in the construction of aerated bricks shall be operated in strict accordance with the regulations. Any problem in the production will affect the strength of the concrete poured on the site. In the process of mixing, transportation and pouring, the separation of concrete mixture shall be avoided first; The vibration should be appropriate. Lack of vibration will lead to poor quality of concrete, even surface quality defects.
