Feb 01, 2012  The composition of the concrete mixture for the panels consisted of CPII E 32 cement, grade zero crushed stone as coarse aggregate, stone powder as fine aggregate, and water. The mixture proportion was 1:2:3 (in weight), with a water/cement ratio of 0.60. The characteristic compressive strength expected for the concrete at 28 days was 20 MPa.

Highlights ELC panels are made of steel U-sections, welded surrounding a concrete panel reinforced. Typical failure modes and the influence of slenderness on the load capacity are studied. The experimental results compared with equations for concrete panels have a similar behavior. The strength of the ELC is higher than other wall panels, due to the contribution of steel U-sections.

Triaxial Shear Test on Soil - Procedure,Advantages

Triaxial shear strength test on soil measures the mechanical properties of the soil. In this test, soil sample is subjected to stress, such that the stress resulted in one direction will be different in perpendicular direction. The material properties of the soil like shear resistance, cohesion and the dilatancy stress is determined from this test. []

May 03, 2019  In general, the compressive strength of concrete has an inverse relationship with its ultimate strain, meaning that high-strength concretes are less ductile than those of lower strength. As shown in Fig. 14 b, the increased compressive strength of the concrete led to a significant reduction in the ductility of the column.
