with proper construction, including steel rods and a cement/sand/pebble mixture in the blocks’ voids, concrete block homes are able to withstand vicious hurricane winds. they are able to handle tornadoes without a problem and most earthquakes as well. fire-resistant
reinforced pre-cast cement concrete paver”blocks and complimentary products used for light, medium, heavy and very heavy traffic paving applications and other applications. 1.2 the standard does not cover concrete masonry units, cellular (hollow) concrete blocks, fly ash masonry blocks, permeable concrete blocks, grid blocks, grass stones and
typically, concrete masonry units have nominal face dimensions of 8 in. (203 mm) by 16 in. (406 mm), available in nominal thicknesses of 4, 6, 8, 10, 12, 14, and 16 in. (102, 152, 203, 254, 305, 356, and 406 mm). nominal dimensions refer to the module size for planning bond patterns and modular layout with respect to door and window openings.
concrete blocks are rectangular concrete masonry units either, solid (other than units used for bonding, such as a half-block) or hollow (open or closed cavity). concrete blocks come in modular sizes and vary by country. yet, their size and mass will be such that one can handle them easily.
cinder blocks are a popular building material for many projects such as foundations, garden walls, fire pits, retaining walls, benches and more. while there’s the standard design that looks like a square figure 8, there are actually many different cinder block designs, shapes and sizes. we set them out below.
concrete bin block 2’x2’x6′ concrete bin blocks are a generic term to describe interlocking, stackable concrete blocks. made with leftover concrete and a great low-cost alternative to jersey barriers, concrete bin blocks carry many names: ecology blocks, lug blocks, mafia blocks, knob blocks, v-blocks, waste blocks, storage blocks, and others.
the u.k. standard for blocks is smaller, measuring 17.3 inches long by 8.5 inches tall by 3.9 inches wide. new zealand standard block sizes are smaller yet, measuring 15.4 inches long by 7.5 inches tall by 7.5 inches wide. concrete blocks are often used in combination with steel reinforcing bars to form reinforced concrete block structures used
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. cement, aggregate, water is used to prepare concrete blocks. the cement-aggregate ratio in concrete blocks is 1:6.
there are generally various types of concrete block used in the construction of the structures such as houses, buildings, etc. they are manufactured in any required shape and size and it may also be concrete or hollow blocks. the distinctive dimensions of concrete blocks are 39 cm x 19 cm x 30 cm or 20 cm or 10 cm or 2 inches, 4 inches, 6 inches, 8
it is used in the industrial buildings subjected to vibrations, sudden impact loading due to machine foundations. it is used in buildings in seismic zones. it is used as lintels over opening for doors, windows, as a column for supporting arches & lintels. it is used as columns or walls subjected to heavy compressive load.
aggregate concrete blocks are typically available in two standard face sizes (length x height) of 440 x 215mm and 390 x 190mm. other face sizes are available to aid manual handling.
concrete masonry units also known as cmu are blocks used in the construction industry to form a concrete block structure like a wall or a fence. these are generally made up of concrete and aggregates of certain design mixtures depending on strength required but systems used as masonry units are non-load bearing in nature or do not and should not be allowed to carry any vertical loads at all.
concrete blocks are a prefabricated material mainly used to build walls. like bricks, the blocks are stacked together and joined with a mortar, usually
concrete blocks are often used to build load-bearing walls. a lighter weight concrete block, manufactured of aerated concrete is also available for construction. this type of block is known aerated concrete (aac) block, or as an autoclave cellular concrete (acc) block.
see below for a fully worked example where we demonstrate how you can use the concrete block calculator to work out how many concrete blocks are needed and the total cost of the building project. otherwise, get your next home improvement project off to an efficient start with our free online block

a dolos (plural: dolosse ) is a reinforced concrete block in a complex geometric shape weighing up to 80 tonnes (88 short tons), that was used in great numbers as a form of coastal management to build revetments for protection against the erosive force of waves from a body of water. due to easy breaking they are no longer being newly deployed.
(sand, gravel) and water. concrete blocks are produced in a large variety of shapes and sizes. they can be produced manually or with the help of machines. most commonly used concrete blocks are sized: length: 40cm (half blocks: 20cm) height: 20cm width: 8/10/15/20cm arcli uses the sizes 14,5 x 29 x 14cm, 14,5 x 14,5 x 14cm (width x length x height)
concrete block (cmu) concrete block is made up of portland cement, fine aggregate, and water and molded into varying shapes. the common size unit is 8″ x 16″ nominal (7-5/8″ x 15-5/8″ actual making 8×16″ with the mortar joint) and weighs approximately 49lbs each. thicknesses available are typically 3, 4, 6, 8, 10, and 12″ nominal.
the concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. this produces a light gray block with a fine surface texture and a high compressive strength. a typical concrete block weighs 38-43 lb (17.2-19.5 kg).
laying the concrete block walls. concrete blocks are typically a 'nominal' 16 inches long. 'nominal' size refers to the size of a block or brick when the thickness of the mortar joint is included. the actual size of the block or brick is less than the nominal size. types of concrete block that you can expect to use are -
concrete blocks are manufactured in required shapes and sizes and these might be solid blocks or hollow blocks. a paver is a block made of stone or concrete used for paving the roadway or backyard of our houses.
bashaw concrete manufactures two sizes of concrete blocks. basic large blocks are 2.5 ft x 2.5 ft x5 ft and weigh approximately 4200 lbs. basic small blocks are 20 inch x 20 inch x 40 inch and weigh approximately 1200 lbs. all our blocks use ½ inch multi-strand cable for lift loops. rebar is never used.
concrete is formed when concrete powder comes into contact with a block of water (source block, flowing or waterlogged). it is not formed by contact with rain ,
