Concrete Block Background A concrete block is primarily used as a building material in the construction of walls. It is sometimes called a concrete masonry unit CMU.
A concrete block is one of several precast concrete products used in construction. The term precast refers to the fact that the blocks are formed and hardened before they are brought to the job site.
Most concrete blocks have one or more hollow cavities, and their sides may be cast smooth or with a design. In use, concrete blocks are stacked one at a time and held together with fresh concrete mortar to form the desired length and height of the wall. Concrete mortar was used by the Romans as early as B.
During the reign of the Roman emperor Caligula, in A. Much of the concrete technology developed by the Romans was lost after the fall of the Roman Empire in the fifth century.
It was not until that the English stonemason Joseph Aspdin developed portland cement, which became one of the key components of modern concrete. The first hollow concrete block was designed in by Harmon S. Palmer in the United States. After 10 years of experimenting, Palmer patented the design in Palmer's blocks were 8 in Byan estimated 1, companies were manufacturing concrete blocks in the United States.
These early blocks were usually cast by hand, and the average output was about 10 blocks per person per hour. Today, concrete block manufacturing is a highly automated process that can produce up to 2, blocks per hour.
Raw Materials 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 lb In general, the concrete mixture used for blocks has a higher percentage of sand and a lower percentage of gravel and water than the concrete mixtures used for general construction purposes.
This produces a very dry, stiff mixture that holds its shape when it is removed from the block mold. If granulated coal or volcanic cinders are used instead of sand and gravel, the resulting block is commonly called a cinder block. This produces a dark gray block with a medium-to-coarse surface texture, good strength, good sound-deadening properties, and a higher thermal insulating value than a concrete block.
A typical cinder block weighs lb Lightweight concrete blocks are made by replacing the sand and gravel with expanded clay, shale, or slate. At this temperature the material bloats, or puffs up, because of the rapid generation of gases caused by the combustion of small quantities of organic material trapped inside.
A typical light-weight block weighs lb Expanded blast furnace slag, as well as natural volcanic materials such as pumice and scoria, are also used to make lightweight blocks. In addition to the basic components, the concrete mixture used to make blocks may also contain various chemicals, called admixtures, to alter curing time, increase compressive strength, or improve workability.
The mixture may have pigments added to give the blocks a uniform color throughout, or the surface of the blocks may be coated with a baked-on glaze to give a decorative effect or to provide protection against chemical attack.
The glazes are usually made with a thermosetting resinous binder, silica sand, and color pigments. Design The shapes and sizes of most common concrete blocks have been standardized to ensure uniform building construction. The most common block size in the United States is referred to as an 8-byby block, with the nominal measurements of 8 in This nominal measurement includes room for a bead of mortar, and the block itself actually measures 7.
Many progressive block manufacturers offer variations on the basic block to achieve unique visual effects or to provide desirable structural features for specialized applications.brick and block making business plan sample.
