Modified lightweight aggregate, repair mortar and preparation method and application thereof
The invention provides a modified lightweight aggregate, repair mortar and a preparation method and application thereof. The modified lightweight aggregate is obtained by mixing and calcining a liquid material and an inorganic lightweight aggregate; wherein the liquid material comprises the following components in parts by weight: 40-60 parts of water glass, 20-45 parts of talcum powder and 15-30 parts of water. The invention provides a novel lightweight aggregate treatment mode, the inorganic lightweight aggregate is obtained by mixing and calcining the water glass and the talcum powder according to a specific proportion, the defects of large water absorption and poor strength of the traditional inorganic lightweight aggregate are avoided, the hydration effect of the cementing material is improved, and the mortar strength is increased; the modified lightweight aggregate is introduced into the mortar, so that the density of the mortar is reduced, the sagging resistance of the mortar is improved, the constructability of the repair mortar for the outer wall system is improved, and the safety of the system is also improved.
本发明提供了一种改性轻质骨料、修复砂浆及其制备方法和应用。所述改性轻质骨料由液料和无机轻质骨料经混合后煅烧得到；其中，所述液料按重量份数计包括：水玻璃40～60份、滑石粉20～45份、水15～30份。本发明提供一种新的轻质骨料处理方式，通过特定比例的水玻璃和滑石粉混合后煅烧得到无机轻质骨料，避免传统无机轻质骨料吸水量大、强度差的缺点，提高胶凝材料水化效果，增加砂浆强度；且在所述砂浆中引入该改性轻质骨料，降低砂浆密度，同时提高砂浆抗垂挂性，提高外墙系统修复砂浆的施工性，也提高了体系的安全性。
