Description

一种水拌轻质预制砂浆
技术领域
本发明涉及预制品，具体涉及一种水拌轻质预制砂浆。
背景技术
目前建筑业需要重量轻且强度好、裂纹少且耐火性能高的预制品。如排烟气道、轻质隔墙等。排烟气道或轻质隔墙在重量不超重的情况下，强度达到技术要求难度较大，反之如果强度达到技术要求，但产品的重量通常会超重，生产成本高，安装难度大。
轻质预制砂浆，能更好的满足以上要求，且耐火性能大幅提高。
轻质预制砂浆，主要由水泥、脱硫石膏、炉渣，再加少量珍珠岩粉，加水搅拌而成。然后注入所需生产的产品模具内。过15分钟后即可脱模，若室温低于10℃时加入少许萘系减水剂，这样生产出来的排烟气道或轻质隔墙产品，具有重量轻、强度好、无裂纹且耐火性能高等优点。
发明内容
本发明针对上述问题，提供了一种水拌轻质预制砂浆。
