Step 1
Basic concrete mortar block is the type of block most masses associate with pulley-block wall construction . There are three type of canonical concrete howitzer block : gray block , fragmented nerve block and exposed aggregate block . Gray stop , also know as the " basic building block " of industriousness , is used in applications where esthetics and lulu are not the master vexation . Gray blocks are installed using trench mortar , and are reinforced with steel in the interior channel . disunited face blocks are fundamentally gray-haired stop that have been altered to produce a approximative , uneven open on the debunk face of the cube . Split face blocks are made by pouring concrete into a double mold . They are physically split apart after heal to produce two blocks . Split aspect blocks are installed the same way as gray block . expose aggregate auction block is concrete block that has been Baroness Dudevant - blast after curing . This process exposes the totality within the concrete , and provides a visually appealing grain on the block brass .
Step 2
Advanced Mortar Concrete Block
Advanced concrete trench mortar blocks are construct to accomplish unequaled ocular effects when meld in a wall . This block character include slump block , and Sonora or fluted block . slack block is a case of concrete blocking that mime the aspect of adobe . It is uniform in sizing and figure but give the appearance of irregularity . This block is also available in different size and colour combinations . The manufacture of Sonora and fluted cylinder block uses molds that make vertical bloodline and a textured fount in the ruined auction block . Sonora and fluted concrete pulley-block are democratic with architects and designers . This case of blockage provides an inexpensive way to make unusual line and texture in walls .
Non-Mortar Concrete Block
Three types of stoppage do not expect of trench mortar to hold in them together . Rather , a system using gravity and extra aim characteristics preserve the rampart integral . Non - mortar concrete blocks include landscape masonry , interlocking AB , and interlocking fencing block . landscape painting Freemasonry is a mortarless concrete block system that has specialized uses , and is favored by architects because of the variety of block shapes and color , and the ease of facility . Landscape masonry can be used as pavers for paseo , or to produce landscape retain wall ( up to 6 feet high without reinforcement ) . Interlocking mortarless AB concrete pulley-block is a stackable block organization used to create visually likeable walls . Only one company currently manufactures AB blocks . AB blocks are extremely popular with contractile organ , and are available from any masonry provider . AB blocks are uncommitted in a variety of sizes , SHAPE and colors . Interlocking fencing block is a hybrid in terminal figure of installation . Mortar is used on the horizontal joint , but not on the vertical joint between blocks . The stop plug into using a tongue - and - vallecula design at each end of the block . These blocks are available in a variety of textures and colors , and are used primarily for fence applications .
Pre-Cast Concrete Walls
Pre - cast concrete rampart are the most expensive method of construct concrete block walls . Pre - cast concrete wall are made in large sections , transported to the job site , and instal by a licensed contractor . The kind of shapes , texture , and color combinations are practically unlimited .
Construction Considerations
All concrete block walls take groundwork construction ( or a footing ) with one exclusion . landscape painting Freemasonry hold walls less than 5 feet improbable do not require a footing . Footings are typically retrace of poured concrete , reinforced with steel rebar , and land up so that there is a level base of operations from which to make the bulwark . empty , concrete blocks are designed to provide for steel reenforcement , which is directly connected to the steel in the ground . Concrete is then poured into the interior TV channel of the paries with the steel in it . This process helps maintain the wall ’s long suit and inflexibility where external military unit may play upon the wall .
