Concrete block is made from Portland Cement, aggregates and water. It is also known as a concrete masonry unit (CMU). As a building material, concrete offers several attractive characteristics to designers and builders, including the following: Durable.

What are CMU walls used for?
Concrete Masonry Units (CMU)
The units are often used when masonry is to form a load-bearing wall or an interior partition between spaces within a building . Concrete masonry units can be manufactured in different sizes and with a variety of face textures.
What is a CMU structure?
CMU is concrete block made from Portland cement, aggregates like stone and quartz, and water . The blocks come in an assortment of shapes and are hollow or solid, with two or three cores or voids. Advantages of CMU Construction.
What is a CMU partition wall?
The Masonry Society's TMS 402 code defines a partition wall as an interior wall without any structural function . It is a non-loadbearing wall that does not support a floor above, does not participate in the lateral system, and is not a wall that resists out-of-plane exterior wind or seismic loads.

Is ICF cheaper than concrete block?
Once a structure is built with ICF there is no comparison to typical frame or block construction. ... The cost of ICF vs. more traditional methods of construction is typically more for the actual construction, but the cost of ownership of an ICF structure is significantly less than the more traditional methods .
Is ICF better than concrete block?
ICFs vs CMUs: Which is Better? ICF walls are monolithic, concrete walls without joints, and are significantly stronger than those built with concrete blocks . BuildBlock ICF technology combines strong and long-lasting concrete and steel reinforcement with the superior insulation of expanded polystyrene (EPS) foam.
Which is a standard component of a CMU?
What are Concrete Masonry Units Made of? CMU are made from cast concrete , such as Portland cement and aggregate, usually sand and fine gravel for high-density blocks. Lower density blocks may use industrial wastes as an aggregate. Lightweight blocks can also be produced using aerated concrete.
What is the difference between a cinder block and concrete block?
Cinder blocks are hollow rectangle-shaped structures usually made of concrete and coal cinders which find use in construction sites. Concrete blocks often, on the other hand, are flattened constructs made of steel, wood or cement.
How are CMU walls made?
The majority of present-day buildings are built using concrete blocks or bricks , which form CMU walls. Similar to stone masonry units, a CMU system stacks together concrete blocks using mortar joints. However, some CMUs are motarless systems that fit into each other through a series of interlocking tongues and grooves.
What is the difference between concrete and masonry?
Concrete is a composition of different elements prepared in a factory while masonry is made on-site of bricks and mortar . They are both durable. Concrete is poured into molds while bricks and mortar are joined to create masonry.
