Architectural masonry offers many different finishes and textures. Among those are: Glaze CMU glazed masonry units, Ground Face units, Filled and Polished Units, Shot Blasted Textured Units, Acoustical sound-absorbing units, and Limestone masonry units. Because of its modular nature, different concrete masonry units can be combined within the same wall to achieve variations in texture, pattern and color. Because of its durable nature, and use of less embodied energy, masonry is a very environmentally friendly building product. Masonry offers a variety of different facial applications that can greatly enhance the decorative appearance of the building. This program will also discuss the critical specification process of masonry for the architect. And, review anticipated life cycle costs of a masonry wall.

Block Manufacturing

The highest quality units on the market are achieved through manufacturing process control of:

chemical compounding

raw blocks

laboratory color control

manufacturing procedures

Concrete Masonry UnitASTM Compliance

ASTM C90 - Standard Specification for Load-Bearing Concrete Masonry Units

ASTM C744 - Standard Specification for Prefaced Concrete Masonry Units

ASTM E119 - Fire Tests of Building Construction and Materials

ASTM E514 - Water Penetration and Leakage through Masonry

ASTM E2432-05 - Standard Guide for the General Principals of Sustainability Relative to Buildings

Water Repellent Admixture

Approved water repellent admixture is added to the block at time of manufacture. The admixture …

yields an integral damp-proof wall system.

provides mold and moisture control and reduces the risk of efflorescence.

offers a denser, more uniform unit without altering the finished appearance of the block.

improves the bond strength and lasts the lifetime of the unit when incorporated into the mortar.

Filled & Polished Concrete Masonry Units

What’s the difference between

Ground Face

and

Filled and Polished

Concrete Masonry Units?

Filled & Polished blocks offer a tight, smooth terrazzo-like finish.

38

After the initial grinding process, the pores and interstices of the ground faces are filled with a cementitious grout to expose the variegated colors of the natural aggregates.

The exposed faces are polished smooth in a multi-stage polishing process.

A factory-applied clear satin gloss acrylic finish accentuates the natural beauty of the aggregates and provides moisture resistance.
