Depth of Soil Exploration Exploration, in general, should be carried out to a depth up to which the increase in pressure due to structural loading is likely to cause perceptible settlement or shear failure of foundation. This depth is known as depth of exploration, which depends upon the following factors. Type of structure Load on … Read more

What is Foundation? Foundation is the lower portion of the building usually located below ground level, which transmits the loads of the super structure to the supporting soil. A foundation is therefore that part of the structure which is in direct contact with the ground to which loads are transmitted. Functions of Foundation 1. Reduction … Read more
The surface course is the uppermost structural layer in an asphalt pavement. In most cases it is the top layer of the pavement and also serves as the wearing course. Since it is directly exposed to traffic and environmental forces, it must be produced with highest quality material. Characteristics of Surface Course The surface course … Read more
Advantages of Welding Joints No hole is required for welding, therefore no reduction of area. So structural members are more effective in taking the load. In welding extra plates (like filler plates, gusseted plates, connecting angles etc,) are not used, which leads to reduced overall weight of the structure. Welded joints are more economical as … Read more
Compaction should not be confused with consolidation. At the end of the consolidation and/or compaction process, a closer packing of soil grains results, which leads to increased shear strength and decreased compressibility and permeability. Difference Between Compaction and Consolidation Soil Compaction It is a dynamic process Compaction is almost instantaneous Densification is due to reduction … Read more
Why to Use Clean Sand for Mortar? Contaminated sand will not bind with cement, hence is weakening the mortar. Also sand with high percentage of clay or silt will weaken the mortar, because the clay or silt contains too many fines that needs to be covered by cement for proper binding. Why Use Fresh Cement … Read more
Steels should be stored in such a way, so as to avoid distortion and to prevent deterioration and corrosion. Steels of different classes should be stored separately. Follow the guidelines given below while storing steel on site. Storing of Steel Reinforcement Store bars of different classes, sizes and lengths separately to facilitate issues in such … Read more
While sampling cement from a lot (consisting of a number of cement bags), the lot is divided into a number of sub-lots. Number of sub-lots into which a lot is to be divided is depends upon the weight of the lot. Use the following table while dividing the lot into sub-lots. Weight of the lot … Read more
