“…Concrete self-insulating blocks have several advantages, ranging from energy and soil conservation to waste disposal and environmental protection [1,2]. Concrete hollow blocks offer better thermal performance, simplified construction, and reduced construction time while also significantly improving thermal and mechanical performance and conserving energy in buildings [3].…”

“…With the implementation of China's national policy on energy conservation and emission reduction, building energy conservation has been highly valued by the local authorities and several codes have been established, with expanded goals to minimize the energy and control energy efficiency to establish sustainable environments [15]. Most approaches to producing new energy-saving concrete selfinsulating blocks involve using recycled aggregate [1,16] and other materials [17]. Huizhi Zhang i sur.…”

This study was designed to satisfy the requirements of energy-saving insulation blocks in severely cold regions, with the thermal and mechanical properties and bulk density comprehensively optimised. An optimal block type was obtained, with the necessary parameters provided and further suggestions for improvement proposed. This study investigated the preparation process and material properties of a new energy-saving self-insulation block. Additionally, both thermal performance and compression tests were designed and conducted on the wall, with the compression performance of the brick and the shear resistance of the wall experimentally studied and optimised using ANSYS.

PurposeRecycled concrete is an economical and environmentally friendly green material. The shear performance of recycled concrete load-bearing masonry is studied, which is great of significance for its promotion and application and also has great significance for the sustainable development of energy materials.Design/methodology/approachIn total, 30 new load-bearing block masonry samples of self-insulating recycled concrete are subjected to pure shear tests, and 42 samples are tested subjected to shear-compression composite shear tests. According to the axial design compression ratio, the test is separated into seven working conditions (0.1–0.8).FindingsAccording to the test results, the recommended formula for the average shear strength along the joint section of recycled concrete block masonry is given, which can be used as a reference for engineering design. The measured shear-compression correlation curves of recycled concrete block masonry are drawn, and the proposed limits of three shear-compression failure characteristics are given. The recommended formula for the average shear strength of masonry under the theory of shear-friction with variable friction coefficient is given, providing a valuable reference for the formulation of relevant specifications and practical engineering design.Originality/valueSimulated elastoplastic analysis and finite element modeling on the specimens are performed to verify the test results.
