All You Need to Know About Concrete
2
  • Durable and low-maintenance, concrete is an
    excellent material for constructing walkways,
    driveways, entrances and backyard patios from,
    and maintains its condition well in those states
    that regularly experience colder climates, too.
    However, concrete is only ever as good as the
    person installing it, so if youre planning to
    have any concrete work carried out at your home,
    be sure to engage with an experienced company who
    are qualified and equipped to work with concrete.

3
  • Here are a few important facts about concrete
    that could help you determine whether to use it
    for a construction project at your home
  • Concrete mixtures
  • Made up of 4 components cement, coarse aggregate
    (such as gravel), fine aggregate (such as sand),
    and water.
  • Concrete finishing
  • Premature finishing and over finishing of
    concrete can quickly and easily result in surface
    defects, such as blisters, dusting, crazing or
    delamination.

4
  • Concrete curing
  • Curing occurs once the concrete has been poured
    and finished, and the longer the curing or
    hydration time, the stronger the concrete.
    Ranging from between 3 to 14 days depending upon
    the type of application, a curing compound can be
    applied that acts as a blanket by forming a thin
    membrane over the concrete to prevent the water
    from evaporating quickly.
  • A concrete professional will know exactly how to
    properly mix, finish and cure it so that it looks
    great and lasts for years.

5
  • Reinforced concrete
  • The process of reinforcing concrete is when wire
    mesh or steel bars are embedded into the concrete
    to carry the tension forces, and the bars are
    often referred to as rebars. Even with rebar,
    concrete will eventually crack due to the natural
    occurrence of changes in temperature and moisture
    cycles, and while reinforcements cannot prevent
    this from happening, they will hold the crack
    faces together.

6
  • The durability of concrete
  • Concrete can easily deteriorate due to
    temperature changes, chemical attacks and
    corrosion of metals to name but a few, but
    exposure to moisture is the most common culprit.
    Concrete is never entirely impermeable
    especially to the slow passage of water vapor
    but a slab of 4 inches of more is impermeable to
    the passage of water from the ground.
  • To prevent water damage and to make concrete more
    durable, there are several things a construction
    professional can do, including lowering the water
    to cement ratio, uniform aggregate gradation and
    density, and using a vapor retarder.

7
  • Cracks can also occur in concrete due to
    shrinkage, causing the lifting of slab edges at
    the joints that is caused by the top and bottom
    of the slab having different moisture and
    temperature levels.
  • As you have read, concrete can be a complex
    construction material, and only someone qualified
    and experienced at working with it, should ever
    be hired to help with your residential or
    commercial construction improvements.
  • Contact local construction companies and ask them
    for advice as to whether a concrete structure is
    right for your needs.
