A cinder block’s weight varies greatly, but it’s generally 36 pounds (16 kg) for an 8-inch-by-8-inch-by-16-inch piece. A smaller cinder block weighs about 24 pounds (10 kg), while a larger block can weigh up to 46 pounds (20 kg).
Cost of cinder block construction
Although cinder blocks are lighter than concrete blocks, they are still more expensive than the latter. In addition, cinder blocks don’t have the same tensile strength. Therefore, the average life span of a cinder block house is lower than that of a traditional home. However, the long-term cost of a cinder block house depends on many factors, including the quality of the blocks used and the expertise of the builder.
The price of a basic 8-x-8-inch cinder block ranges from $2 to $10 per square foot, depending on the size and location of the house. The cinder blocks used for residential construction are lighter and weaker than concrete, but they’re still a viable alternative for some projects. While these blocks are not as strong as concrete, they’re more durable than their concrete cousins and are preferred by contractors. Both types of blocks feature open cells where reinforcing materials are placed. Additionally, they’re also ideal for plumbing and electrical lines.
Size of cinder block
The standard dimensions of a cinder block are 16 inches long by eight inches deep. Actual cinder blocks are much smaller. The smaller size is necessary because the blocks must be fabricated with mortar, which is about three-eighths of an inch thick. However, this does not mean that they are necessarily smaller than the standard sizes. In fact, they may be slightly larger or smaller than the standard sizes, allowing for mortar joints.
When calculating the size of a cinder block, do not include the windows and doors. In addition, make sure to use a high foundation. Remember that cinder blocks are susceptible to collapse under moisture action and can cause structural damage. If you plan to build a house with cinder blocks, use a tape type foundation. The average cinder block is only 0.08 square meters. However, for a one-story building, you will need at least two square meters of cinder blocks.
Strength of cinder block
Until the 1970s, cinder block foundations were the norm for new homes. Although poured concrete walls are more durable and popular, cinder block foundations are easier to build. In fact, a poured concrete wall system accounts for 72% of new homes with a full basement. In comparison, concrete block walls account for about 25% of the national market. Each type of foundation has its advantages and disadvantages.
One major advantage of concrete blocks over cinder blocks is their density. The former is much heavier than the latter, due to the addition of sand and gravel to its concrete mix. The latter is much more prone to buckling and bowing, however, because it contains a high proportion of ash. This makes it ideal for smaller construction projects. A typical cinder block weighs about 25 pounds per square foot.
