本文主要讲述的是对于基本的混凝土配合比，有不同的材料分类。此外，使用不同形式的钢具有不同的抗拉强度也是很重要的。现在，为保险和保险库创建制定标准的保险公司实验室要求建造保险柜，使它们免受任何形式的电气和机械攻击或工具等的攻击。TL 15型保险柜的最小重量通常在750磅左右，可以作为一个独立的保险柜放置，也可以作为一个更大的混凝土保险柜的一部分。本篇布里斯托论文代写文章由英国论文通AssignmentPass辅导网整理，供大家参考阅读。
There are different material classifications with the basic concrete mix. In addition, the use of different forms of steel with different tensile strengths is also significant. Now the underwriter laboratories which set the standards for safe and vault creation requires the safes to be built so that they are protected against any form of electrical and mechanical attack or attack by tools, etc. The TL 15 style safe is usually around 750 pounds minimum and might be placed as a standalone safe or might be considered as part of a larger concrete block of safe in a secure premise.
The body wall of this material is usually made of hearth steel which is at least a minimum of one inch in thickness. The tensile strength of this hearth steel is quite high and is expected to be around 50,000 P.S.I. or higher. The walls are welded with open hearth steel and is fastened with a ¼ inch penetration form of weld. Electrical conductors would be made use of with this form of fastening in order to ensure the direct locking mechanism is well hidden.
Those in alkali-silica rich areas might exhibit a high level of re-activity. Gradation of aggregates has to be checked, too. Only those aggregates that give maximum density to the concrete used and at the same time are also of good workability should be selected. Fine aggregate content in the case of crushed aggregate mixes sometimes needs to be checked as the amount of fine aggregate could result in the increased retention of moisture. However, when the fine aggregate content is low, the strength of the structure becomes low because of binding issues. Therefore, when selecting material and mixes, it is critical to consider the effect on one another.
The manufacturing process would also differ based on the form of materials used. For instance, consider the concrete reinforced with steel material that is used. Such a safe wall design would more often be built as custom orders only. The safe wall manufacturing process would first start from the design process, for instance, as one of the aspects of a house or bank building.
