Rat trap bond is a kind of brick masonry wall in which bricks are laid in a vertical position instead of the traditional horizontal position. This arrangement creates a hollow space in the wall. It is also known as the Chinese brick bond. In this arrangement, shinner and rowlock are visible on the face of … Read more
This blog post is related advantages of thermal insulation in buildings. Let us get started. Thermal insulation is used to separate the building temperature from the external environment. Due to thermal insulation building interior is less affected by external temperature. Warm protection helps safeguard a structure’s inside so that it’s less impacted by the outside … Read more
Before starting the discussion about the Difference Between Short Column And Long Column, let’s get a brief idea about the short column and the long column. Short Column If the ratio of the effective length of a column to its least lateral dimension does not exceed 12, it is known as a short column. The … Read more
What is Cavity Wall? A cavity wall or hollow wall is constructed with two separate walls called leaves-or skins with a cavity gap or space in between two walls. Both walls are joined together by metal ties. (see figure below) The primary purpose of the cavity wall is to provide better insulation in the building. It … Read more
Workability of concrete is the characteristic of freshly mixed concrete which defines the ease and homogeneity with which it can be mixed, transported, placed, compacted, and finished as described by ACI Standard 116R-90 (ACI 1990b). As per ASTM “that property determining the effort needed to manipulate a freshly mixed quantity of concrete with minimum loss … Read more
