Example Embodiment
[0028] The present invention also provides a method for preparing recycled aggregate stone powder anti-seismic hollow block for building a frame-filled wall. The specific steps are as follows:
[0029] Firstly, the cement, stone powder, and fine aggregate are mixed by wheel milling. After mixing evenly, add polycarboxylate superplasticizer and water, and keep stirring until the cement slurry can completely cover the fine aggregate particles; then add Recycle coarse aggregate, and continue to add the remaining polycarboxylic acid superplasticizer and water. After forced mixing, the dry recycled aggregate stone powder concrete is prepared, and the dry recycled aggregate stone powder concrete is sent to the hydraulic forming machine in batches , The semi-finished product is obtained by high-frequency vibration and compression molding; after the semi-finished product is allowed to stand for 12 to 24 hours, and then autoclaved for 10 to 12 hours, a shock-resistant hollow masonry made o...

[0043] Example 1
[0044] Firstly, the cement, stone powder, and fine aggregate are mixed by wheel milling. After mixing evenly, add polycarboxylate superplasticizer and water, and keep stirring until the cement slurry can completely cover the fine aggregate particles; then add Recycle coarse aggregate, and continue to add the remaining polycarboxylic acid superplasticizer and water. After forced mixing, the dry recycled aggregate stone powder concrete is prepared, and the dry recycled aggregate stone powder concrete is sent to the hydraulic forming machine in batches , The semi-finished product is obtained by high-frequency vibration and compression molding; after the semi-finished product is allowed to stand for 12 to 24 hours, and then autoclaved for 10 to 12 hours, a shock-resistant hollow masonry made of recycled aggregate stone powder for building a frame-filled wall can be obtained Block finished product.

Example Embodiment
[0049] Example 2
[0050] It is basically the same as Example 1, except that:
[0051] The mass mixing ratio of the cement, recycled coarse aggregate, stone powder, fine aggregate and water is 1:2.95:0.60:2.65:0.35.
[0052] The polycarboxylic acid superplasticizer is a self-made AMPS modified polyacrylic acid superplasticizer, and its blending amount is 0.60% of the cement mass.
[0053] n (polyethylene glycol monomethyl ether acrylate): n (sodium methacryl sulfonate): n (sodium 2-acrylamide-2-methacryl sulfonate): n (acrylic acid) = 1.0: 2.5: 1.0 : 7.0, MPEG relative molecular mass is 1200, initiator APS dosage is 6% of the total mass of the mixed monomer solution, the polymerization temperature is 90°C and the polymerization time is 3.5h.
