A Guide to the Workability of Concrete

-

There is no specific definition of the workability of concrete. It is more or less a subjective term with broad conception. It refers to how the concrete is mixed, placed, consolidated and finished with the least homogeneity. 





This blog will shed some crucial aspects about the workability of concrete whether it is high-strength concrete or regular concrete. Read further for more information. 

What is the Impact of the Workability of Concrete?


Workability has a huge impact on the strength, quality, cost of labor for placement as well as appearance. Concrete that has good workability can bring many attributes together in equilibrium and result in an optimum quality product with longevity. 


Factors Affecting Workability


Different factors affect the workability of concrete. Let's delve into more details.


1. Water/Cement Ratio: A significant amount of cement or cementitious materials usually result in greater strength. In case there is a scarcity of water that means poor strength development and an uncooperative mix that resists easy placement and finishing. 



2. The Size and Shape of Aggregates: Mixes that have a lesser amount of aggregates are less workable than the larger size aggregates. The aggregates which are elongated, flaky, and angular are hard to mix and place and covers a large area which declines workability. 



3. Admixtures: There are different types of admixtures altering the workability of fresh concrete, either by design or as a side effect. Superplasticizer which is a surfactant can lower down the attraction between cement and aggregate particles that result in the mixtures that are quite flowy without the negative strength and segregation effects of too much water. 



These are the factors that affect the workability of concrete and these factors are considered strictly while constructing buildings in Lilongwe for the betterment of structures.

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
