Deciding which premixed concrete blend to use? There are differences between general purpose premixed, fiber-reinforced, countertop concrete, and fast-setting concrete and this DIY guide to types of concrete is here to help.
Concrete is one of the building materials that revolutionized the construction industry. Yet its so
common that it doesnt get the respect it deserves. This is understandable its
Its underfoot in homes and offices; it permits vast highway systems. Even concrete countertops are
showing up in upscale homes! What most people dont know is how many types of concrete formulations there
are. This article will examine some of the most common ones.
Concrete VS Cement
Many people confuse the two terms concrete and cement. The two terms are
The fact is that cement is an ingredient of concrete. Most commonly, concrete is a mixture of
portland cement, water, and the aggregates: sand and gravel.
Fortunately for the DIY types out there, manufacturers have mixed and bagged formulations of
concrete (minus the water) for specific types of home improvement projects.
Concrete is available for larger projects by renting portable cement mixers from home improvement
stores and tool rental outlets. DIY projects such as porches and patios are good candidates for portable concrete mixers. The wet concrete is poured into a
and then finished.
Which Type of Concrete to Use for which DIY Project?
A DIY homeowner isnt going to use a concrete contractor for small projects so its
important to know which type of concrete to use. The following list will explain which type is right
for the weekend project.
General purpose premixed concrete This mix of portland cement, gravel, and sand is generally rated at 4000 psi for compressive strength. This premixed concrete is ideal for building curbs, floors, sidewalks, patios, setting posts, and steps.
Fiber-reinforced concrete mix This blend adds reinforcing fibers to the sand and gravel aggregates. Where is this handy? In places where impact is expected.
Places such as steps, walkways, and garage or shed floors are good examples of areas to use this concrete blend.
Countertop concrete mix This concrete mix is made especially for pouring concrete countertops for kitchen counters.The concrete countertop has been rising in popularity and makes a fine DIY kitchen project.
Since countertop concrete is a low moisture mix, a special proprietary additive has been added to it. It is also formulated to reduce shrinkage to minimize surface cracking while the concrete dries. It finishes off at about 5000 psi after a month.
Fast-setting concrete mix As the name implies, this product is quick to set! Does that mean working like a maniac? Absolutely not. This is for DIY projects that dont require a form, such as setting posts for decks, fence posts, mailboxes, and building swing sets.
Simply dig the hole in the ground, pour in the concrete and fill it with water. It sets in about half an hour. Its a good choice when the weather is questionable.
These are some of the excellent choices of concrete mixes available to the DIY world. Manufacturers have responded to consumer needs. The concrete countertop is a great example of this. DIY concrete projects are not only fun, theyre easier than ever!
