Like other materials, however, concrete has it fair share of cons, which are quite difficult to deal with even by the most highly skilled of builders. Building the toughest structures require expertise in producing quality concrete, and this isn’t something any person can do. It’s no wonder construction projects are often supervised by civil engineers and architects. Following are three of the most common challenges these professionals have to take on when working with concrete.
- Crazing.The formation of interconnected fine cracks found on some finished concrete structures is called crazing. This occurs when the cement paste rises to the surface and shrinks. This can be avoided by using a moderate slump of concrete without bleeding and segregation, not finishing concrete until it’s completely dry, and not sprinkling water during finishing.
- Scaling.Inadequate curing may result in poor concrete strength. This becomes obvious when the concrete surface starts peeling away, particularly after a tremor or when water seeps through voids within the concrete block. It can be prevented through proper mixing of aggregates and using enough amount of water.
- Cracking.Unlike crazing and scaling that occurs on the surface of concrete, cracking occurs within the structure, making it quite dangerous. When you see cracks on your wall or girders that look serious, call a building inspector right away to check if they are signs of imminent collapse.
The Role of Concrete Forms
While most of the challenges with concrete mentioned above have to do with the mixture of cement, water, and aggregates, they are still greatly influenced by the way the concrete is formed. A concrete form is designed to hold the concrete together throughout the curing stage. How well the concrete forms and hardens to the design specification depends on the quality of the concrete forms used.
Thanks to modern concrete forming systems provided by top companies like LECO Concrete Forms, builders have a better chance at meeting design specifications with precision. Because these systems are made of metal, they can be shaped into the most intricate of designs. They are also very tough so they can hold the weight of concrete throughout the entire curing process. If you are looking for the best concrete forming systems and concrete wall forms for sale, make sure to turn to the right supplier so that you can get the value for your money.
