How is Humidity Testing of Concrete Slabs Significant?

-

Concrete is an integral part of any building or construction floor application. Though concrete is known for its longevity and strength, a few types of concrete are incapable of withstanding the harsh weather conditions. As a result of which they get cracked, become dusty, start getting damaged with water.




Everyone in the construction industry should be aware that concrete can hide inherent faults that are never visible to naked eyes. What's wrong with it? It can adversely affect any building situation later on.


If you wish to incorporate any concrete in a construction site, employ building construction services in Malawi:


Condensation


You might consider concrete as a solid and dry substance on first look; however, it is very porous and can absorb moisture from its surrounding factors. This locked moisture can fundamentally alter the concrete properties and can damage the surface coating. The moisture can make its way to concrete from below the slab or from above. 


Sensitive Results


A couple of tests are performed on concrete in the concrete laboratory for testing to quantify the amount of moisture absorbed by concrete to avoid potential future damage. One test named in-situ test or f2170 test can determine whether a particular type of concrete can be used at your construction site. In the in-situ RH test, the tester inserts a micro-sensor fitted into a hole drilled in the test concrete through a sleeve.


Then, the reading is given to the sensor right away. It is rated as the most accurate humidity test for concrete as the probes are almost unaffected by the environmental change on the surface. 


Prevention





Another test to calculate the relative humidity percentage in a concrete slab or flooring is the F2420 test. This test is also known as the Hood Test in the industry. The reason for carrying out this test is the same; to test that the moisture permeates the concrete slab or floor and holds the potential to retard or affect the floor system. The flooring system manufacturers recommend moisture/humidity tests before they apply any covering on the concrete floor slabs.

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 bee

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 cutter, the different blades in the concret

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 silic
