Yellow River Silt Bearing Porous Brick Masonry Mechanical Tests

The Yellow River washes out the loess plateau and schleps a mass of mud and sand to the downstream of The Yellow River, then the mud and sand deposit onto the bed of the river to form silt because of the lower velocity of the flow. The Yellow River silt is a kind of broad and huge natural waste. If we use the Yellow River silt to exploit wall material, we can not only clean up the Yellow River silt, but also provide a new outlet for the wall material innovation. Utilizing this natural waste to exploit wall material has social, economic, environmental benefits.However, we must build integrated dynamic theory system of the Yellow River silt cellular brick, a kind of new wall material, before it is used in the actual engineering. This paper is developed on the basis of the foregone experiments of its material performance.This paper studies the basic dynamic performance of the Yellow River silt cellular bricking structures as follows:(1) Based on the study of compressive experiment, we discuss its compressive deformation performance, destructive characters and intensity theory; in the meanwhile, we provide the proposal calculation formula.(2) Based on the regression analysis of the experimental data, we get its proposed formula of compressive stress-strain curve; based on the proposed formula we also get the calculation formula of its elastic modulus.(3) Based on the experimental research of shear strength, we get its shear destructive characters and shear strength; moreover, we make the regression analysis and put forward corresponding proposed formula.(4) Based on the study of transfixion-section and dentiform-section bending tensile experiments, we analyze the two kinds of bending tensile performance especially destructive forms respectively, furthermore, we also discuss calculating formula of their strength.The analyzing means of this paper is based on the experiments. The experimental study on the...
