Water Quality Tests In Concrete Laboratory Testing

-
Just as the quality of raw materials needs to be checked frequently, the water quality needs to be looked out for. There are different quality checks for the water to be used for construction purposes to determine the suitability of water. These tests are usually conducted in a laboratory with a controlled environment. InstaCrete is a reasonably prominent company of the construction industry in Lilongwe known to support fellow construction companies with excellent services and construction material. The company provides ready to mix concrete transported directly from the batch plant to the construction site. This direct transportation offers dual benefits of reducing construction time and assisting with the labor.
Concrete Laboratory Testing

Instacrete ensures to take all the necessary measures to help you build a construction marvel, even if it requires providing the customers with concrete laboratory testing. The following is a list of water quality tests that must be conducted to ensure that the water used is suitable for construction. Read on to plunge into the details. ·

pH value test
pH stands for the potential for hydrogen. The pH test determines the acidity or alkaline nature of the water sample. It accounts for any impurities present in the water samples.

Limits of acidity test
For every 100 ml of a water sample, it should not require more than 5ml of 0.02 normal NaOH. To determine the acidity of water samples, phenolphthalein is used as an indicator.

Limits of alkalinity test
For every 100 ml of a sample of the water, it should not require more than 25ml of 0.02 normal H2SO4. To determine the alkalinity of water samples, a mixed indicator is used.

Concrete laboratory testing ensures that water from the source undergoes all the tests and is used for construction only if it passes all the tests. These tests are repeated every three months to ensure the quality of water is good enough.

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...

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...

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...
