Study on recycled aerogel mortar: how the ratio of mortar to bone affects the evolution of thermophysical properties

Research overview

According to the research included in Volume 547 of Construction and Building Materials, the authors Chunhong Chen, Guoxian Feng, Haofeng Chen, Yuwei Lu, and Pinghua Zhu investigated the mechanism of the paste to aggregate ratio around the evolution of thermal physical properties of aerogel incorporated recycled mortar. The study was published on November 14, 2026.

The core issue of research concern

Recycled mortar replaces natural aggregates with recycled aggregates, which is a technological path for resource utilization in the field of construction and home decoration.

. The introduction of aerogel aims to reduce the thermal conductivity of mortar and improve the thermal insulation capacity. In the study, the ratio of slurry to bone is regarded as a key ratio parameter that affects the internal composition and structure of mortar. Its change will affect the relative ratio between aerogel, recycled aggregate and slurry, and then affect the evolution process of thermal physical properties of materials. The study takes “mechanism” as the starting point to illustrate that the mortar to bone ratio is not a single process parameter, but a formula variable related to the thermal and physical properties of mortar.

Significance for the construction and home decoration materials industry

For building insulation mortar, the stability of thermal physical properties is directly related to the wall insulation effect and long-term performance.

. This study suggests that in the formulation design of recycled mortar containing aerogel, the ratio of slurry to bone should be considered in coordination with the amount of aerogel and the characteristics of recycled aggregate, and the ratio should not be determined by a single index. For enterprises engaged in the development of architectural coatings, insulation and flame retardant materials, and mortar based home decoration materials, this approach can serve as a reference direction for formula screening and performance verification. It should be pointed out that this study focuses on the thermophysical evolution mechanism of the mortar body and does not involve polymer additive systems. However, from the perspective of the overall formula of building materials, the weather stability and long-term performance maintenance of mortar materials often require the participation of additives such as antioxidants and light stabilizers to slow down the aging of materials under heat, oxygen, and light. Especially in building materials such as PVC profiles and sealants that are exposed to outdoor environments for a long time, weather resistance and stability are routine considerations in formula design; The application of antioxidants and light stabilizers is also a common technical means to improve the durability of building materials. The discussion on the relationship between proportioning and performance evolution in this study can provide methodological references for understanding the performance regulation of multi-component building material systems.

Objective description

The source only provided the research title, publishing information and author information, and did not disclose the details of specific experimental data, conclusion values and the dosage of aerogel. Therefore, this article does not make any inferences about the specific performance improvement of the study, and the relevant formula design still needs to be based on the complete paper data.
