Most probable reasons to lose the strength in concreting mixture

Most probable reasons to lose the strength in concreting mixture

Whether it was a project of a multi-story building or a simple BBQ base, the rules of physics and material engineering apply in the same way. Because you cannot afford to lose the strength in the structure, it is always better to know the possible reasons why the strength of the structure would be lower well beforehand. That way, you can take the necessary precautions to protect the structural integrity regardless of how small or large it was.

The use of impure components to the mixture

The purity of water is the key element that guarantees the highest strength. The use of impure water to mix the components has always been the standard method used in the commercial setting. But you cannot expect the mixture to live up to its standards by using pure water, but impure aggregates. The bottom line is that the optimal bonding takes place only if all the components are of adequate quality.

Concreting under the rain

Checking the slump of any batch that comes by a truck mixture is the standard site procedure. But despite the quality of the mixture inside the mixture, checking the slump under the rain would show you just how impactful rain can be on a mixture. This is the reason why you should never carry out a concreting under the rain; the dilution is always going to affect the quality of the mixture.

Improper proportions of the materials

Even if you had the purest materials for the mixture, it’s a challenge to get the proportions right. Most people end up with disappointment regarding quickly failing structures just because of the poor proportions in the mixture. Thus, it’s always mindful to choose ready mix bags that contain all the components in a concreting mixture in the most appropriate way. Since we all can measure a specific volume of water to get the mixture right, you never ever have to worry about the quality of the cemented structure in any way. Because unlike mixing each and every component individually, achieving the industry level standard is not going to be impossible when following these procedures.

Poorly supported formwork

The purpose of the formwork is to hold the mixture until it settles. But most people wouldn’t notice just how weak the supports are until the pouring begins. Hence, be sure to double-check your formwork so that inadequate flowing of grout will not be there.

Poor covering for the reinforcement

The purpose of covering for reinforcement is to provide protection against rusting and fire. Although the fire risk is generally lower, the rusting issue would always be there unless you ensure the proper covering. The best way to ensure covering is by laying down the reinforcement on the prepared subfloor and ensuring that none of the reinforcement bars have any space issues. That way, once the bars are being tied together, there won’t be any surprising lack of covering issues. When it comes to worse, you should at least consider removing an extra bar because you won’t be able to stop the spreading of the rusting unless you stop it at the start itself.
