Concrete corner blocks are placed so that one end of the plane is exposed to the exterior and secured with the stretcher block. One block corner is plain, while the other has a stretcher design.

The parallel length of concrete stretcher blocks is put parallel to the face.Ĭoncrete corner blocks are utilized at the masonry’s corners and the ends of windows and doors. Concrete stretcher blocks commonly use hollow concrete blocks. Hollow concrete blocks come in various shapes, sizes, and designs, depending on the shape, needs, and design.Ĭoncrete stretcher blocks are also employed at the masonry’s corners. The nominal size of concrete blocks, according to the ‘Research Designs & Standards Organization of Indian Railways,’ is as follows: Half-sized blocks are cubical and have one core, while full-sized blocks are rectangular and have two cores.

Standard hollow concrete blocks come in two sizes: Full size and half size. These blocks reduce the natural weight of masonry structures while also improving physical wall qualities like noise and thermal insulation. It reduces labour costs on the job site while also speeding up the construction process and saving cement and steel. In masonry construction, hollow concrete blocks are typically employed. As a result, constructing concrete masonry takes less time than brick masonry. They’re compared to bricks that come in big sizes.

These solid blocks are ideal for large-scale projects such as force-bearing walls. They’re sturdy and give structures a lot of solidities. Solid concrete blocks, which are highly heavyweight and formed by aggregate, are primarily utilized in construction projects. In concrete blocks, the cement-aggregate ratio is 1:6. Concrete blocks are made from cement, aggregate, and water. 39cm x 19cm x (30cm or 20 cm or 10cm) or 2 inch, 4 inch, 6 inch, 8 inch, 10 inch, and 12-inch unit configurations are the most popular concrete block sizes. Concrete blocks come in various shapes and sizes, and they can be solid or hollow. These construction blocks can be ‘Hollow’ or ‘Solid,’ formed of ordinary or lightweight concrete in various specified sizes, depending on the precise requirements. Once the mortar joints have become “thumbprint” hard, use a jointing tool to smooth the fresh joints and remove any excess mortar.A Concrete Block is a ‘Building Block’ composed entirely of concrete that is then mortared together to make an imposing, long-lasting construction. Using a mason’s line as a guide for the remaining block, continue building the wall until it is complete. To set the next course of block, apply a one-inch thick mortar bed along top of the first course.Īt the end of the wall, set an “8x8x8” half block into the mortar bed with the smooth side facing out. Repeat steps 6 and 7, adjusting the blocks to be flush and level continue this process until the first course is completed. Using the same process, set the opposite corner block. The mortar should be workable but firm enough to support the weight of the block.īutter the inside end of the first block and then press the block into the mortar bed to create a 3/8 inch mortar joint. Furrow the mortar bed using the tip of the trowel to create a “v” to help distribute the mortar evenly. The proper consistency is achieved when the wet mortar will “hang” on a trowelĭampen the footing surface with water and place a one-inch bed of mortar on the footing. TIP: when preparing to place a trowel full of mortar, gently “snap” the trowel downward to removeĪny excess mortar. Snap a chalk line on each side of the block wall as a reference line. Lay out the block, making sure to leave a 3/8 inch gap between the blocks to allow for the vertical mortar joints (i.e., a typical 8x8x16 block is actually 15-5/8 inches long and 7-5/8 inches high to accommodate the mortar joint). Rebar should be placed in every other masonry core to provide structural support.įor masonry cores over 4 inches wide, QUIKRETE Core Fill Grout – Coarse should be poured around the rebar for masonry cores under 4 inches wide, QUIKRETE Core Fill Grout-Fine should be used.

NOTE: it is important to check local building codes for construction requirements in your area.įor load-bearing walls, tie rods should be set a minimum of 6 inches into the concrete footing before it is set. Footings should be a minimum of twice the width of the concrete block (i.e., a typical 8x8x16 block would require a 16-inch wide footing) and extend below the frost line. When working with cement-based products, always wear eye protection and waterproof gloves.Įnsure a solid footing.
