The 6- inch thick block walls were reinforced with 5 re-bars placed vertically and spaced at 32 o.c., and the 12-inch blocks were reinforced with 2- 4 vert. at 48 o.c. In addition to wall thickness, the other primary factor for the design of concrete masonry walls is limiting the spacing between lateral supports.
Construction of thin walls with hollow blocks is very common. So, it helps to reduced space used in construction and increase the floor area. 8. Bonding of mortar and plaster. Since the surfaces of hollow blocks are rough, this provides for good bonding between mortar and plaster.
The hollow-core design combines with mortarless construction to allow water to drain freely from behind the segmental retaining wall. Incidental water moves easily through a vertical drain that is formed by the layer of wall rock placed behind the block and in the block cores.
1. Hollow concrete blocks. Commonly used in the construction industry, concrete hollow blocks are usually manufactured using lightweight aggregates with a certain design load depending on the nature of member it will be used into.
Just enter the dimensions of your wall project, and the concrete block calculator will figure out how many blocks are needed. For example, a 10 x 10 wall using a 16 x 8 x 8 block will require an estimated 120 blocks and cost about $185 for material. If youre building a retaining wall, then check out our retaining wall

Those that use cinders fly ash or bottom ash are called cinder blocks in the United States, breeze blocks breeze is a synonym of ash in the United Kingdom, and hollow blocks in the Philippines.
Assured Quality: - Fully automatic block plant. Better sound absorption: - Being hollow in nature. Reduced thickness of plaster: - Due to size accuracy and less cement consumption due to fewer joints. Load bearing walls: - Due to higher strength of blocks. Recommended for earth quake resistance.
HOLLOW CONCRETE BLOCK Introduction: Hollow concrete blocks are substitutes for conventional bricks and stones in building construction. They are lighter than bricks, easier to place and also confer economics in foundation cost and consumption of cement.
Characteristics. A concrete block is referred to as a concrete masonry unit, or CMU, in the construction industry. Concrete blocks can be solid or hollow, with two or three cores or voids. The blocks also come in a range of standard shapes. Generally, concrete blocks measure 16 inches long by 8 inches wide by 8 inches high,
1 a hollow-block wall is as strong as its weakest link which is a hollow-block; 2 a hollow-block wall needs plaster. Take a close look at any outside-wall at any building here in the Philippines; the plaster cracks and lets water through to the steel bars in the hollow-blocks; rust = misery.

Up to 60% of heat lost through Cavity Block Walls Cavity blocks 9 hollow blocks were often used in the past for home construction due to cost considerations, and they are particularly common in the Dublin area. This type of construction was very poor in terms of heat retention and comfort levels.
Concrete blocks are manufactured in required shape and sizes and these may be solid or hollow blocks. The common size of concrete blocks is 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.

Coatings are often are applied to concrete block in order to prevent water penetration; some of these include Portland cement paints, latex paints, oil- and rubber-based coatings, epoxy coatings, alkyd paints, urethanes and silicones;
Concrete blocks are an affordable building material that can be used for many construction projects and are suited very well for construction walls for foundations or utility buildings. Concrete blocks typically have holes in the center to reduce the weight, material needed, and cost.
For brick walls, a common thickness is 230mm 9" , and for concrete block walls, common thicknesses are 200mm 8" , 150mm 6" and 100mm 4" . In the building trade, the thickness of the walls excludes the plaster, so if a wall is plastered on both sides, its actual thickness will be 1" or 1.5" more than its stated thickness in an architectural
