Mar 2019 CONCRETE BLOCKS VS POURED CONCRETE WALLS
Although made using the same ingredients, Sephaku Cement explains the different recipes followed to create poured concrete walls and walls made with concrete blocks. Differences between poured concrete walls and walls erected using concrete blocks begin with the very basic construct of the two variants.
Pros and Cons of Poured Concrete Walls
Where poured concrete walls are constructed using semi-fluid concrete poured into pre-built forms, these poured concrete creations harden to form one solid and uniform partition. When installing a poured concrete wall, as a starting point, building a concrete wall from scratch using a semi-fluid concrete mix requires a framework to mould the shape of the wall before the project has even begun. This means that before the Portland cement and aggregate can even be mixed, a fairly labour intensive process to create a mould to cast the wall must be built before mixing and pouring the concrete. Over and above the work needed in preparation of casting a poured concrete wall, the placing and compaction is of the utmost importance for durability and longevity of the structure and the curing process required for the fluid concrete mix can also be a time consuming process.
The time required for the concrete to adequately cure is that which must not be neglected in order to ensure the poured concrete project results in a steadfast concrete construct complete with an efficient load bearing capacity. While a poured concrete wall may seemingly require added effort, a monolithic concrete wall boasts a far more impressive load bearing capacity than its “Brick-like” concrete cousin construct. It also offers a versatile solution made to form a diverse range of shapes, curves, bevelled and decorative frameworks. Poured concrete walls are also known to leak far less than concrete blocks but do run a greater risk to encounter freeze-thaw and other types of cracks and fissures as a result of the unbroken, continuous concrete structure.
Benefits and Features of Concrete Blocked Walls
Concrete walls erected using concrete blocks are made of concrete masonry units (CMU’s) that are joined together with mortar to create a similar walled structure with the same type of patterns resembled in brick masonry. Pieced together to form its very own form of concrete masonry brickwork, concrete blocks are cost effective and time conscious, which means little to no long-term maintenance. Concrete block walls also naturally keep temperatures cool in the summer and warm in the winter as a result of their thermal mass, making these the most ideal materials to use when building a home. Not as aesthetically pleasing to the eye as poured concrete walls that offer a smooth and uniform appearance, once erected walls built using concrete blocks are usually plastered with mortar or rhyolite after and later painted to add a finishing touch.
Whether installing a uniform, poured concrete wall or building a walled construct using concrete masonry units, concrete offers a cost effective and long standing solution free from various vulnerabilities that other walled solutions are at risk to.
