When you finally do sit down to interview with a prospective employer and you are really, sincerely interested in working for them, then it is important for you to be prepared to handle every facet of the job interview. If you can focus yourself on the most important facets of the initial employment interview with a company that you are serious about working for, then you should be able to relax yourself, as well as to be more in control of the message that you are trying to send to the prospective employer. By now you should have a pretty basic idea of the biggest and most critical mistakes that need to be avoided in your initial job interview if you want to be successful in proving to the interviewer that you are the best candidate for the job. There is an art to job interviews, and by taking the tips and information in this report seriously, you have already taken positive steps to mastering this excellent art. Once you learn how to master job interviews, you will not have trouble s...

A girder is a support beam used in construction. Girders often have an I-beam cross section for strength, but may also have a box shape, Z shape or other forms. Girder is the term used to denote the main horizontal support of a structure which supports smaller beams. A girder is commonly used many times in the building of bridges, and planes. The Warren type girder combines strength with economy of materials and can therefore be relatively light. Patented in 1848 by its designers James Warren and Willoughby Theobald Monzani, its structure consists of longitudinal members joined only by angled cross-members, forming alternately inverted equilateral triangle-shaped spaces along its length, ensuring that no individual strut, beam, or tie is subject to bending or torsional straining forces, but only to tension or compression. It is an improvement over the Neville truss which uses a spacing configuration of isosceles triangles.

1) insert your hand in cement it should give cool feeling not warm(moisture content). 2)it should not content any lumps or dust 3)it should be green color 4)take pinch of cement rubbed between fingers it should give smooth finish(feeling). 5)take handful of cement and throw it into bucket full of water it should float on the surface of water for some time.

The excessive presence of silt in the sand reduces the bonding between cement and aggregates. It increases water demand for concrete. This reduces the strength of the concrete.   It also modifies the setting times of concrete. It can cause cracks in hardened concrete. Hence, silt content is undesirable in the sand. Here is a simple method to find out the silt content in sand.   The permissible limit of silt content The silt content should be less than 8 % by volume.   What to do if silt content is more than the allowable limit? The sand having silt content more than 8 %, should not be used in concrete. However, the sand can be used after washing. It brings the sand content below the permissible limit.   Frequency of Testing of silt content The silt content should be tested daily and once for each truck at the time of unloading at sites.

A Retaining Wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. The basement wall is thus one form of retaining wall. However, the term is most often used to refer to a cantilever retaining wall, which is a freestanding structure without lateral support at its top Typically retaining walls are cantilevered from a footing extending up beyond the grade on one side and retaining a higher level grade on the opposite side. The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures. The most important consideration in proper design and installation of retaining walls is to recognize and counteract the fact that the retained material is attempting to move forward and downslope due to gravity. This creates lateral earth pressure behind the wall which depends on the angle of internal friction (phi) and the cohesive strengt...
