How Concrete is the Green and Sustainable Material?

-

 For ages, concrete has been looked down upon as an unsustainable material, and that it has a great contribution to the carbon footprint. Though it is the most indispensable material, it still has garnered a very unexpected and negative reputation.


However, very few are aware that concrete also has a great contribution to reduce co2 emissions over its lifetime. These days many construction industries in Malawi promote concrete as a green material due to its sustainability. 


If you are curious to know how concrete green and sustainable material is, this blog will reveal this aspect of the concrete. 


  • Durability 


Concrete makes long-lasting structures durable that will not rust or burn. If we talk about life span, then this double or triple the other building materials. 


  • The efficiency of the resource 


Concrete is made of raw materials such as limestone that is the most abundant material found on the earth. Apart from these, concrete is also made up of fly ash, slag element, and silica fume that all are the byproducts of power plants, manufacturing facilities, etc. 


  • Thermal mass 


Interestingly, concrete walls, foundations, and floors are energy efficient, they are benefitted from concrete inherent thermal mass, or they can absorb or retain heat. That means people can have the advantage of cutting their heating and cooling bills. 


  • Reflectivity 


Reflectivity is another advantage offered by concrete structures. The pavements and roofs with light color absorb less heat and reflect more solar radiation than dark color material like asphalt. 


  • Retain stormwater 


Another plus point is that concrete structures can retain the water of storms. Pervious concrete is that kind of structural concrete with a sponge-like network of voids, so the water passes through easily. When used for the structures such as sidewalks, parking lots, and other pavements, this type of concrete helps retain stormwater runoff. 


  • Minimal waste 


Concrete is produced in quantities as per the requirement of the projects. The leftover concrete after the construction can be crushed or recycled for making other things. 

 


Upon considering these factors you can count on concrete as a green material and rely on construction industries in Lilongwe for sustainable practices.

The Major Strategic Use For Prestressed Concrete In Construction World

There is no denying that ready-mix concrete gives excellent strength and enough durability for the structure. You might have come across a plethora of benefits of concrete by using concrete in construction. But this piece would be emphasizing more on the question, “why do we need prestressed concrete?” Ready Mix Concrete  If you are a contractor or too keen in the construction business, you might have noticed the crack formation under the concrete element after completion of the structure. This happens due to the load applied to the concrete top surface after hardened. Initially, the concrete element deforms at the mid-portion and, after a long run, the crack forms on the concrete. These issues can be rectified using chemical mixtures for small scale structures. But, for large ones such as bridges, dams, and high-rise buildings, the process of rectification can be a tad confusing. And the rectifying cost can also be over the top. The prestressed concrete technology has...

Which equipment is used popularly to cut the joints in cement concrete pavement construction?

In a construction site, we see hundreds of equipment and tools that are used in the entire construction work. But when  concrete construction in Lilongwe  at a place starts where there is an old building made, or a new building is being constructed. Often, the joints in the cement concrete pavement construction have to be cut, demolished, and then reconstructed on the place. So, popularly, to cut the joint in the  construction concrete cement , there are two instruments that are mainly used.  The Two Instruments Are: Concrete Saws -  The concrete saws are often used in the  building construction services   where there is the requirement to demolish a prior made building and remove the old concrete. The concrete saws are also used at the places where they need to cut control joints where the concrete is hardening.  Furthermore, to make the concrete saw sharp, the good quality diamond blades are used to cut the concrete. Besides the diamond cutt...
