Geotechnical Engineering Basic Interview Questions MCQ quiz Click here for Geotech Quiz 1.What are the basic principles of foundation design? 1. The foundation must be stable against shear failure of the supporting soil. 2. The foundation must not settle beyond a tolerable limit to avoid damage to the structure. 2.How do you determine the bearing capacity of soil? The ultimate bearing capacity , or the allowable soil pressure, can be calculated either from bearing capacity theories or from some of the in situ tests. The most popular bearing capacity calculation methods are 1. Terzaghi's bearing capacity theory 2. The general bearing capacity equations 3. Field tests According to Terzaghi's bearing capacity theory the soil's ultimate bearing capacity is dependent on density , cohesion, angle of friction of soil, shape, breadth and depth of footing. It also depends on the depth of...
Mortar Mixing in Masonry Work In construction industry, mixing of mortar ingredients plays a very important role. Improper mixing may lead to the development of cracks and reduction in strength. What is Mortar? It is the binding material of various building materials like bricks, stones and concrete blocks etc. Mixture of cement and sand along with the water is called wet mortar mix. Mixture of cement and sand along without water is called Dry mortar mix . Common problems in construction while mortar mixing and their effects. · Without measurement box. The mortar ingredients to be added with proper measurements. Often it seen that the mortars are mixed with random thumb rule without standard measuring box which leads to the variation in mortar ratio and hence it adversely affects the strength. · Without non absorben...
