Embodiment 1
[0052] Embodiment 1. A low-density, high-strength self-insulating ceramsite hollow block is composed of the following components in parts by weight, wherein: cement: 1, ceramsite: 1, slag: 0.56, Stone powder: 0.56, sand: 0.33, modifier: 0.15, water: 0.55;
[0053] Described modifying agent is polyvinyl acetate;
[0054] The ceramsite is grade 400-500, and the particle size distribution is 5-12mm.
[0055] Its specific production method is as follows:
[0056] A. Soak the ceramsite in water for 24 hours to make it fully absorb water, then drain the water for later use;
[0057] B, dissolving the modifying agent in water to prepare an aqueous modifying agent solution;
[0058] C. Send the ceramsite and cement into the mixer for dry mixing. After mixing evenly, add 1 / 2 modifier aqueous solution and mix into ceramsite mortar so that the cement particles can fully cover the ceramsite. Then add slag, stone powder and sand and stir together. During the process, add the remaining ...
