CONCRETE BLOCKS CMUS CODE

Two concrete blocks are manufactured together and mechanically split into two halves after the block has been put on firing operation.

Resistance to against corrosive chemicals,Ģ.2 ASTM Code for Glazed Concrete Masonry Units (CMU)Īll Glazed Concrete Masonry Units must adhere to the standards set forth by the ASTM codes that are given below for reference S.NO.Numerous glazing options based on coloring and faux patterns are available in the market. Glazed concrete masonry units are prepared as conventional concrete blocks but the surface is covered with resin-based coating that provides a tile like ceramic glaze finishing. Glazed – Concrete Masonry Unit (CMU) Glazed Concrete Masonry Unit (CMU) Make sure the architect is taking the coloring manufacturer into confidence about the selection or output of the desired color for CMU.

By this way one can certify the uniform coloring on the CMU walls. Second option for getting consistent coloring is to paint the CMU surface or plaster the CMU blocks with a colored mortar.

Randomly selected concrete blocks should be checked in each batch of transport.

The material engineer or the architect must get at least 3 samples of colorized concrete blocks to verify the consistency in coloring from a given manufacturer.

Thus, consistency in coloring is questionable sometimes. Even during blending and casting, there can be few areas in which coloring pigments are much getter in quantity then elsewhere. The consistent surface coloring of the concrete masonry units can be attained by following the two methods: Mixing Coloring Pigments during CastingĮven if the material engineer orders the colored concrete masonry blocks from the same manufacturing plant, there will be seen a variation in coloring.

How to achieve consistent Surface Coloring of CMU? Following are most common colors that are used in CMUs. 1.1 Coloring Varieties for CMUĬoloring pigments are available in variety of colors and combination of several colors can also be used to blend them together to get new color variations. Colored – Concrete Masonry Unit (CMU) Colored Concrete Masonry Unit (CMU)Ī variety of coloring pigments can be added to the concrete masonry units during the casting or one can add the coloring pigments to the mortar for attaining the colorized surface finishing of the concrete masonry units. Other finishes include color, which is achieved by adding pigments to the mix during production, and patterned textures that are created with a trowel after the block has been poured.Īll the details of surface finishes of concrete masonry units are given in details 1. The most common finish on concrete masonry units is a smooth or rough texture, which is achieved by applying different types of aggregates to the surface of the blocks.
