As we know that brick is the important construction unit.In previous blog posts, we studied mechanical properties and physical properties of building material.If you didn’t read it, please check it.We need to ensure several qualities of good bricks to resist loads acting on it.
We need to maintain the quality of bricks to avoid the defects caused in bricks.So here I am going to write about the qualities of good bricks.
Properties of Good bricks
Colour is the primary thing which describes the aesthetic appearance of the brick and it is one of the requirements of good brick masonry.The colour is attained by burning of clays.
We know that bricks are manufactured by heating different types of clay.The brick should have deep red or cherish colour as a measure of uniform chemical composition.
The main characteristics of good brick earth in strength point of view is crushing strength of bricks.Crushing strength is an important property for checking the quality of bricks.The crushing strength of bricks should not be less than 10N/mm².
3.Size and Shape
The bricks should uniform rectangular surfaces and these surfaces should be parallel to each other.The bricks should have sharper edges.If you don’t know, what are the different shapes of bricks used in construction, please read the linked article.
The texture is another important for checking the qualities of bricks.After placing these bricks, we need plaster them.So as to ensure good quality plastering, the surface should be smooth and uniform texture.The texture is another important for checking the qualities of bricks.
The water absorption should not exceed 20 percent of its dry weight when the brick is immersed in water for 24 hours.
The bricks should be sufficient hard when no impression will not create by scratching with the nails.
When two bricks struck, the metallic sound should be produced.These are qualities of good bricks we need to ensure while the manufacturing of brick.
