Performance

Expansion & Porosity

When you use aluminum paste for autoclaved aerated concrete aac blocks, you see a big change in how the blocks form. The paste reacts with the mix and creates hydrogen gas. This gas forms bubbles, which turn into pores inside the block. These pores make the blocks light and easy to handle. You usually find that about 70–80% of the block is made up of these pores. The aluminum paste creates large pores, which help lower the block’s density and improve insulation.

If you add more aluminum paste, you get more hydrogen gas. This means more pores and a lighter block. But you need to be careful. Too much paste can make the pores too big or uneven. The size and spread of these pores also depend on how long you mix the paste and what other materials you use. For example:

• Aluminum paste creates macro pores, making up 45–55% of the total porosity.
• More paste means more gas, which increases porosity and lowers density.
• Stirring time and foam stabilizers also change how the pores form.
• Aluminum paste gives you fewer but larger pores than aluminum powder.

If you want blocks with good insulation and low weight, you need to watch how much aluminum paste you use. You also need to pay attention to the mixing process.

Consistency

You want every batch of autoclaved aerated concrete blocks to look and perform the same. The size of the aluminum particles plays a big role here. Fine aluminum powder, between 1 and 10 micrometers, helps you get even bubbles. This gives you a block with a smooth, even structure. These blocks keep heat in or out better, which saves energy.

If you use coarse aluminum powder, bigger than 10 micrometers, you get large, uneven bubbles. This can make the block weak and less reliable. To keep things consistent, many producers use ball milling to grind the aluminum powder down to the right size. They also use machines to sort the powder by size. This way, you get the same results every time you make a batch.

You can see that the right particle size and good mixing help you make strong, reliable blocks. This is important if you want to keep your customers happy and avoid problems with autoclaved aerated concrete blocks price or quality.

Challenges

You might run into some problems when working with aluminum paste for autoclaved aerated concrete aac blocks. Sometimes, the gas forms too quickly or too slowly. If the gas comes out too fast, the bubbles can pop or get trapped, making the block uneven. If the gas comes out too slow, you might not get enough pores.

Here are some common issues and ways to fix them:

• Control the speed of gas release to match how thick the mix gets. Try to keep the gas release at about 6–15ml in 2 minutes.
• Keep the mix temperature between 40–60°C. This helps the bubbles form evenly.
• Use aluminum paste with high active aluminum (at least 85%) and fine particles (less than 3% left on a 0.075mm sieve).
• Adjust the calcium-silicon ratio to stay between 0.55 and 0.80. Too much alkalinity can stop the aluminum from reacting.
• Add foam stabilizers, like soluble oil, to keep the bubbles from popping. This can make the bubbles last 30–50% longer.
• Check your raw materials, watch the process, and test the finished blocks for strength and gas generation.
• Use ball milling and sorting to get the right particle size and keep the mix even.
• Follow safety rules. Use water-based aluminum paste to avoid dust explosions, and treat wastewater properly.

Tip: If you want to avoid problems, always check your materials and keep an eye on the process. Good training and careful work help you get the best results from your aerated autoclaved concrete.

When you follow these steps, you can make autoclaved aerated concrete aac common blockwork that is strong, light, and reliable. You also keep your costs down and avoid issues with autoclaved aerated concrete blocks price.

Benefits of Aluminum Paste for Autoclaved Aerated Concrete AAC Blocks

Quality Improvement

You want your blocks to be better than others. Aluminum paste helps you do this. When you add it, the paste reacts and makes hydrogen gas. This gas forms small air pockets inside each block. These air pockets trap air and act as natural barriers. The blocks keep heat out in summer and hold warmth in winter.

Here’s what happens when you use aluminum paste for autoclaved aerated concrete aac blocks:

• The blocks are lighter, so you can carry and install them easily.
• The blocks are stronger and can handle more weight than blocks with other foaming agents.
• The insulation is better, so buildings stay comfortable.
• The pores are even, so every block looks and works the same.

Let’s look at some numbers. With aluminum paste, blocks can reach a compressive strength of 42 MPa after 28 days. Blocks with synthetic foaming agents only reach about 33 MPa. That means the blocks are 27% stronger. They last longer and do not break easily.

You also get better insulation. The small particles in aluminum paste make even air pockets. These pockets slow down heat moving through the block. Your blocks keep buildings cool in summer and warm in winter.

Tip: If you want blocks that save energy and lower bills, use aluminum paste. You will see a difference in comfort and cost.

Process Efficiency

You want your production to go well. Aluminum paste helps with this. The paste mixes well with cement, lime, and fly ash. You do not have to worry about clumps or uneven bubbles. The mix stays smooth and the blocks come out the same every time.

New ways to make aluminum paste have made things better. Makers use pure aluminum powder. They treat the powder so it does not rust and stays stable. They grind it to the right size. Additives like thickeners and dispersants stop the paste from clumping. The mix pours easily and sets just right.

Here’s how these changes help you:

• Mixing and pouring are faster, so you save time.
• There are fewer mistakes, so you waste less and spend less.
• Gas forms evenly, so every block is the same.
• The paste works with many raw materials, so you can use what you have.

You also help the planet. Makers recycle and use clean ways to make the paste. This lowers your carbon footprint and helps you meet green building rules.

Note: When you use aluminum paste, you get good results and save money. You do not spend much on repairs or new blocks. Your autoclaved aerated concrete blockwork stays strong and works well.

If you want to keep your autoclaved aerated concrete blocks price low and your quality high, aluminum paste is a smart choice. You get blocks that work well, save energy, and last longer. Your projects go smoother, and your customers are happy.

سهولة الاستخدام

Mixing

You want your blocks to turn out right every time. Mixing plays a big part in this. Start by dry mixing your cement, lime, gypsum, and sand or fly ash. This step helps you blend all the dry parts together. Next, add water slowly. Keep an eye on the water-to-solid ratio. You want the mix to feel smooth, not too thick or too thin.

Now comes the important part. Add the عجينة الألومنيوم quickly and mix it in well. The reaction starts as soon as the paste hits the slurry. Mix for about 3 to 5 minutes at a steady speed. This helps bubbles form evenly, making your blocks light and strong. If you mix too long, you might lose some of the gas, and your blocks could turn out heavy or uneven.

Tip: Always mix the aluminum paste in right after you add water. Don’t wait, or you might not get the bubbles you need.

السلامة

Handling aluminum paste means you need to stay safe. Store the paste in a cool, dry place. Keep it away from acids, bases, and things that can catch fire. When you work with the paste, wear gloves, long sleeves, and a mask. This keeps dust off your skin and out of your lungs.

Here are some safety steps you should follow:

• Use non-sparking tools and flame-retardant clothes.
• Make sure your work area has good airflow.
• Never use water or foam to put out an aluminum fire. Use a Class D fire extinguisher or dry sand.
