Innovative and multifunctional mortars for renders and panels were manufactured using white photocatalytic and non-photocatalytic cement as binder. Unconventional aggregates, based on lightweight materials with high specific surface and adsorbent properties, were adopted in order to investigate the possible ability to passively improve indoor air quality. The reference mortar was manufactured with traditional calcareous sand. Results show that even if the mechanical properties of mortars with unconventional aggregates generally decrease, they remain acceptable for application as render. The innovative mortars were able to passively improve indoor air quality in terms of transpirability (70% higher), moisture buffering ability (65% higher) and depolluting capacity (up to 75% higher) compared to traditional ones under the current test conditions.
采用白色光催化水泥和非光催化水泥作为粘结剂，制备了用于抹灰和面板的创新型多功能砂浆。为了研究被动改善室内空气质量的可能性，采用了基于具有高比表面积和吸附性能的轻质材料的非常规集料。参考砂浆采用传统钙质砂制备。结果表明，即使含有非常规集料的砂浆的力学性能普遍下降，但仍可接受用于抹灰。在当前测试条件下，与传统砂浆相比，创新型砂浆在透气性（高70%）、吸湿缓冲能力（高65%）和去污能力（高75%）方面能够被动改善室内空气质量。
