Conclusion of slump test?
The difference in level between the height of the mould and that of the highest point of the subsided concrete is measured. This difference in height in mm. is taken as Slump of Concrete.
What is the purpose of Slump Test and explain the procedure of the testing?
Slump test is the most commonly used method of measuring workability of concretewhich can be employed either in laboratory or at site of work.ProcedureThe mould is placed on a smooth, horizontal,rigid and non-absorbant surface The mould is then filled in four layers, each approximately 1/ 4 of the height of the mould. Each layer istamped 25 times by the tamping rod taking Slump Test Apparatus care to distribute the strokes evenly over the cross section. After the top layer has been rodded,the concrete is struck off level with a trowel and tamping rod. The mould is removed from the concrete immediately by raising it slowly and carefully in a vertical direction. This allows theconcrete to subside. This subsidence is referred as SLUMP of concrete. The difference in levelbetween the height of the mould and that of the highest point of the subsided concrete ismeasured. This difference in height in mm is taken as Slump of Concrete.
What is the difference between box culvert and pipe?
Basically, a culvert means a covered hydraulic structure which conveys fluid. Therefore in a broad sense, pipe culverts in a small scale represent normal pipes like precast concrete pipes. In terms of hydraulic performance, circular section is the best geometrical sections among all. Therefore, for relative small discharge, precast concrete pipes and ductile iron pipes are normally used which are circular in shape. But for applications of very large flow, precast concrete pipes and ductile iron pipes may not be available in current market. In this connection, cast-in-situ construction has to be employed. It is beyond doubt that the fabrication of formwork for circular shape is difficult when compared with normal box culvert structures. However, circular shape is the most hydraulic efficient structure which means for a given discharge, the area of flow is minimum. Therefore, it helps to save the cost of extra linings required for the choice of box culverts. However, box culverts do possess some advantages. For example, they can cope with large flow situation where headroom is limited because the height of box culverts can be reduced while the size of pipe culverts is fixed. Secondly, for some difficult site conditions, e.g. excavation of structure in rock, for the same equivalent cross-sectional area, the width of box culverts can be designed to be smaller than that of pipe culverts and this enhances smaller amount of excavation and backfilling
What does a Threshold Inspector do?
A threshold inspector is a certified building inspector who works for a consulting / engineering firm. If a building exceeds either a height, square footage, or occupancy load, the client usually funding the project is required by law to hire a threshold inspector. In addition to performing structural inspections, a threshold inspector will oversee certain activities during building such as pouring concrete and post tensioning. Threshold inspectors can be considered a form of quality control seeing that the are hired by the developers and not the general contractor, therefore not having to answer to the GC.
What size of Concrete foundation for 40 KW diesel generator set?
1.Do not install the Gen set on the loose send or clay. 2.Foundation should be designed considering safe bearing capacity of soil. 3.The length and breadth of foundation should be at least 300mm more than base rail length and breadth respectively. 4.Ensure that the concrete is completely set and cured before positioning the genset. 5.It is recommended to have foundation height about 250-300 mm above ground level, it help to maintain cleanliness of genset. 6.Foundation should evenly flat diagonally as well as across the length. Ensure complete base rail should be rest on foundation and no gap between base rail and foundation. 7.For roof top installation ensure that the load of D G set is completely transfer on pillar and beam structure & please consult structure engineer for more details.
