Reversed Cyclic

Experiments of a piece of comparable block wall and five pieces of block walls with different constructional type subjected to low reversed cyclic loading have been conducted. Investigation has been made on the failure pattern, hysteretic loop curves, displacement-restoring capacity and displacement ductility of walls. The experimental results revealed that the seismic performance of block masonry walls, which used the constructional column and concrete strips, was improved remarkably. It set a sound basis for further analysis research and engineering practice on AAC load-bearing walls in the future.

Aerated Concrete

This article deals with the strength and thermophysical test results made on the basis of the masonry samples of cellular autoclave curing concrete (aerated concrete blocks) with the use of polyurethane adhesive. Aerated concrete masonry walling with the use of polyurethane adhesive is indicated herein to be technologically feasible and economically viable. The major advantage of the masonry option under consideration lies in the following aspect: thermal conductivity of polyurethane adhesive used to fasten aerated concrete blocks in masonry walls is significantly less than thermal conductivity of concrete adhesives and mortars. For this reason, thermal insulation properties of the masonry with polyurethane adhesive appear to be better comparatively to the block masonry made with the usage of concrete adhesives of any other type. On the ground of the tests conducted the following was resumed: it is acceptable to carry out masonry works with the use of aerated concrete blocks and polyurethane adhesive in construction of exterior and interior nonbearing walls provided appropriate justifying calculations are made.

Aerated Concrete

The non-autoclaved aerated concrete block with greater than 7.5Mpa compressive strength is produced by using iron tailings, lime, aluminum powder, caustic alkali, water, cement and gypsum in the laboratory after the experimental study on the property of iron tailings produced by Anshan Iron and Steel Group. The optimal mix proportion is finally determined by adopting orthogonal experimental method, the evaluating indicator is compressive strength. Aerated concrete block that is made from iron tailing is trial produced according to the national standards, and then its strength is determined by sample examination.

Building material innovations in various interlocking concrete block masonry from local materials to withstand lateral earthquake forces is an exciting issue in masonry wall research. The block hook has an advantage in the interlocking system's invention to withstand loads in the in-plane and out-of-plane orientations commonly required by the masonry walls against earthquake forces. Reviews of the investigation of in-plane and out-of-plane masonry walls have rarely been found in previous studies. In this paper, the results of a series of experimental tests with different interlocking models in resisting the simultaneous in-plane shear and out-of-plane bending actions on concrete blocks are presented. This paper presents a research investigation of various interlocking concrete blocks' mechanical properties with different hook thicknesses. Discussion of the trends mentioned above and their implications towards interlocking concrete block mechanical properties is provided.
