The standard clay brick weighs around 5 pounds, on the other hand, an eight-inch concrete block can weight as much as 43 pounds. The shelf life of concrete is lesser than those of clay bricks. Concrete works well for around 60 to years, while clay bricks have been known to last for years and more.
Porotherm is a world-class product for environment-friendly clay bricks. These are one smart walling material that peruses the advantages of natural bricks and clay. The fact that they are made of natural substances and are hollow from inside makes them far more efficient than the traditional solid bricks and blocks. Stating a few advantages of porotherm over other walling solutions.
That is all for now! We hope this guide helps you understand the sheer difference between Concrete and Clay bricks. Also, you were able to select the perfect building bricks for your project. For expert advice visit www. Authored by a Building Expert from Wienerberger India. Comparison Clay Bricks Vs. Optimal proportions of sand, clay and water along with the drying and firing temperature are integral to the quality of the hardened brick.
Unlike clay brickwork, concrete block masonry is a relatively recent development which started being used as a building material in the midth century. Concrete blocks are composed of Portland cement, aggregates and water with production being highly automated in large industrial plants. The durability of concrete block masonry is less dependant on externalities, and more on design and construction errors. While concrete can fall susceptible to things like efflorescence the migration of salts from the interior to the surface material of the masonry the effects are mainly aesthetic, and without compromise to structural integrity.
Furthermore, pathologies can be prevented by deploying low-absorption blocks with high compressive strength and rebar protection. Masonry materials expand and contract due to changes in moisture levels during wet weather reversible moisture movement. Clay bricks rarely exhibit movements in excess of 1mm per 10 metres of walling. Because concrete is more porous, cement bricks exhibit reversible expansion and contraction in the range of mm per 10m of walling. Clay bricks have a once off, permanent expansion after manufacture due to the firing process that extracts all moisture from the brick.
This expansion is between 0 and 0. All building materials also undergo daily thermal expansion and contraction and these daily temperature swings can result in stress cracks over time.
We have extremes of heat, compared with the extremes of cold experienced in the northern hemisphere. In winter rainfall regions, the combined factors of low outdoor temperatures, rain and frost require special consideration to prevent water condensation and damage due to damp on interior walls of all types.
When looking in a bit more detail it becomes easier to see the visual differences between clay right and concrete left bricks. The colour in concrete bricks come from pigment added to concrete mix, rather than an inherent property of the raw clay material, so they tend to have the appearance of coloured concrete.
It is easier to differentiate clay and concrete bricks when they are of a single colour because the surface texture is more obvious. However, it can be difficult to identify concrete bricks when they have had secondary processes applied during manufacturing.
Also, dyes can be applied to concrete brick surface to mimic the dark spots and patches that are created on clay bricks during firing in the kiln. The only way to be certain of which type of brick you are buying is to ask to see the data sheet attached to the brick. Concrete bricks tend to be assessed against the concrete block standard BS , which has different requirements for the declaration of performance.
