According to Eton aerated concrete block with one-line and two-line cavity with different strength axle pressure and shearing test of through structure are made in order to understand basic properties of aerated concrete block as well as the influences of mortar strength and block strength on masonry strength.

Leakage often takes place on the exterior walls with light weight masonry in the frame structure, frame shear wall structure, special shaped columns frame structure or short shear wall structure at the coast areas with more rainstorms.

Firstly,the compressive strengths of hollow block masonry specimens with natural aggregates and recycled aggregates,while some was mixed with fly-ash or polypropyl- ene fibers,were tested and compared.

A restoring-force experimental investigation on the seismic behaviors of reinforced block masonry shear wall with opening on one-forth-scale has been made.
