As a supplier of raw materials for AAC blocks, I understand the importance of proper storage to maintain the integrity of these materials. In this blog, I will discuss the key storage requirements for the main raw materials used in AAC block production. <a href=\"https:\/\/www.wdaacblockmachine.com\/aac-block-making-machine\/raw-material-preparation-aac-blocks\/\">Raw Material Preparation AAC Blocks<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.wdaacblockmachine.com\/uploads\/202338197\/small\/aac-block-vertical-cutting-machine3f1314b6-304c-4ae2-b117-9672419b30af.jpg\"><\/p>\n<h3>Cement<\/h3>\n<p>Cement is one of the primary raw materials in AAC block manufacturing. It provides the binding strength that holds the block together. Proper storage of cement is essential to prevent it from absorbing moisture, which can lead to premature setting and a decrease in its effectiveness.<\/p>\n<ul>\n<li><strong>Storage in Silos or Bins<\/strong>: Cement should be stored in airtight silos or bins to protect it from humidity. Silos are ideal for large &#8211; scale storage as they can be sealed to prevent moisture ingress. The silos should be equipped with level indicators to monitor the cement level.<\/li>\n<li><strong>Temperature Control<\/strong>: Cement storage areas should be maintained at a relatively stable temperature. Extreme temperature fluctuations can affect the quality of the cement. Generally, a temperature range of 10 &#8211; 30\u00b0C is considered optimal.<\/li>\n<li><strong>Protection from Contamination<\/strong>: The storage area should be clean and free from dust, debris, and other contaminants. Any foreign substances in the cement can affect the chemical reactions during the AAC block production process.<\/li>\n<\/ul>\n<h3>Lime<\/h3>\n<p>Lime is another important raw material in AAC block production. It reacts with silica in the presence of water to form calcium silicate hydrates, which contribute to the strength of the blocks.<\/p>\n<ul>\n<li><strong>Dry Storage<\/strong>: Lime is highly reactive with water. Therefore, it must be stored in a dry environment. Storage in sealed containers or silos is recommended. Lime should be protected from rain, snow, and high humidity.<\/li>\n<li><strong>Separation from Other Materials<\/strong>: Lime should be stored separately from other raw materials, especially those that can react with it. For example, it should be kept away from acidic substances.<\/li>\n<li><strong>Regular Inspection<\/strong>: Periodic inspection of the lime storage is necessary to check for signs of caking or other degradation. If caking occurs, the lime may need to be discarded or processed to restore its usability.<\/li>\n<\/ul>\n<h3>Sand<\/h3>\n<p>Sand is a major component of AAC blocks, providing the necessary aggregates.<\/p>\n<ul>\n<li><strong>Outdoor Storage with Cover<\/strong>: Sand can be stored outdoors, but it should be covered with a waterproof tarp to protect it from rain and excessive moisture. This helps to maintain the moisture content of the sand within an acceptable range.<\/li>\n<li><strong>Grading and Segregation<\/strong>: Sand should be stored in separate piles based on its particle size and quality. This ensures that the right type of sand is used in the AAC block production process, which is crucial for achieving the desired strength and texture of the blocks.<\/li>\n<li><strong>Cleanliness<\/strong>: The storage area for sand should be free from organic matter, dirt, and other impurities. Contaminated sand can affect the chemical and physical properties of the AAC blocks.<\/li>\n<\/ul>\n<h3>Aluminum Powder<\/h3>\n<p>Aluminum powder is used as a foaming agent in AAC block production. It reacts with the alkaline environment in the mixture to produce hydrogen gas, which creates the porous structure of the blocks.<\/p>\n<ul>\n<li><strong>Cool and Dry Storage<\/strong>: Aluminum powder should be stored in a cool and dry place. High temperatures and humidity can cause the aluminum powder to oxidize, reducing its effectiveness as a foaming agent.<\/li>\n<li><strong>Sealed Containers<\/strong>: It should be stored in sealed containers to prevent contact with air and moisture. The containers should be made of materials that do not react with aluminum.<\/li>\n<li><strong>Safety Precautions<\/strong>: Aluminum powder is flammable, so proper safety measures should be taken during storage. The storage area should be well &#8211; ventilated and away from sources of ignition.<\/li>\n<\/ul>\n<h3>Fly Ash<\/h3>\n<p>Fly ash is a by &#8211; product of coal combustion and is often used as a partial replacement for cement in AAC block production.<\/p>\n<ul>\n<li><strong>Storage in Silos or Bags<\/strong>: Fly ash can be stored in silos similar to cement or in sealed bags. Silos are more suitable for large &#8211; scale storage, while bags are convenient for smaller quantities.<\/li>\n<li><strong>Moisture Control<\/strong>: Similar to cement, fly ash should be protected from moisture. Excessive moisture can cause the fly ash to clump, making it difficult to use in the production process.<\/li>\n<li><strong>Quality Monitoring<\/strong>: Regular quality checks should be conducted on the stored fly ash to ensure that it meets the required specifications for AAC block production.<\/li>\n<\/ul>\n<h3>Gypsum<\/h3>\n<p><img decoding=\"async\" src=\"https:\/\/www.wdaacblockmachine.com\/uploads\/202338197\/small\/aac-block-handing-crane18f80af7-dac0-485e-91a1-d49bcee55dc9.jpg\"><\/p>\n<p>Gypsum is used in AAC block production to control the setting time of the mixture.<\/p>\n<ul>\n<li><strong>Dry Storage<\/strong>: Gypsum should be stored in a dry environment to prevent it from absorbing moisture and losing its effectiveness. It can be stored in bags or silos.<\/li>\n<li><strong>Protection from Contamination<\/strong>: The storage area should be clean to prevent contamination of the gypsum. Any foreign substances in the gypsum can affect the setting time and the quality of the AAC blocks.<\/li>\n<\/ul>\n<h3>General Storage Considerations<\/h3>\n<ul>\n<li><strong>Inventory Management<\/strong>: A proper inventory management system should be in place to keep track of the raw materials. This includes monitoring the quantity, quality, and expiration dates (if applicable) of the materials.<\/li>\n<li><strong>Safety<\/strong>: Safety is of utmost importance in the storage of AAC block raw materials. This includes proper handling of flammable and reactive materials, as well as ensuring that the storage facilities are structurally sound.<\/li>\n<li><strong>Accessibility<\/strong>: The storage area should be designed in such a way that the raw materials can be easily accessed for production. This helps to improve the efficiency of the manufacturing process.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/www.wdaacblockmachine.com\/aac-block-making-machine\/batching-pouring-and-pre-curing-section\/\">Batching Pouring and Pre-curing Section<\/a> As a supplier of raw materials for AAC blocks, I am committed to providing high &#8211; quality products.
