For the well-informed layman to perform as a hobby, mixing and pouring concrete is a clear enough process, although it is usually best to enable experienced professionals to do the job when it is an important aspect of constructing structurally sound. An engineer may know how and why cement functions as it does, but may not have familiarity in a job environment with the particular construction strategies.
A general contractor with another background will have a good understanding of dealing with cement, but a qualified construction team who deals with it every day would certainly not have the same experience.
Regardless of the angle from which you view your concrete task, there are a few general rules to ensure that when dealing with concrete, you become more successful.
Tensile Strength of Concrete
The concrete’s tensile strength is its resistance to pushing and bending forces rather than its ability to bear loads of compression. A bridge requires tensile strength because it bends under load or because of weather conditions. As the building settles over time, a building foundation or concrete walls face tensile requirements.
Using their cured product, the manufacturer determines the tensile and compression strength, a slump test is performed on the job site.
Essentially, filling a cup with the wet mix, turning it upside down, and removing the cup is how the slump test starts, then timing how long it keeps its shape determines the concrete is properly mixed according to whether strength or maneuverability is required of the project.
Use Concrete Slab Calculator
Failure to determine the correct amount of concrete by mixing or ordering with a concrete slab calculator can be a costly error for a specific project. Too much is a mess to clean up, too little will require a second application that may not bond well or provide a single pour’s strength. The important aspect is not simply to trust the plans, but to assess the area after completing the grade and applying gravel and dirt when required. Don’t forget to account for the rebar, and understand that as it cures and the water evaporates, the concrete will shrink.
Choosing and Using a Concrete Saw
Four main types of concrete cutting saws are available, each with its own range of advantages for various applications. A walk behind the saw is the most powerful and accurate, capable of performing quick cuts for all day cutting tasks with minimal stress on the user. A handheld cutting edge saw is designed to finish work around the edges and can be cut easily through the rebar reinforcements of the concrete. Wet saws spray the cutting water, keeping dust down for better visibility and cutting control. Not exactly the saw itself is a diamond blade, but it is essential to make clean cuts that will show when the job is finished.
