Oral History

Ever wondered what sparked the mid-century modern infatuation with those concrete blocks with decorative cutouts that surround so many traditional homes? Dating back to the s, breeze blocks, or architectural screen blocks offer a decorative screen wall or fence with an architectural appeal. Both residential and commercial buildings started to use breeze blocks with decorative hole patterns within their design.

Breeze blocks are often made from ashes of coal. They are bonded together with Portland cement and often used for walls bearing smaller loads. While we may associate breeze blocks more with mid-century modern designs, they actually started in the Art Deco period.

Masonry , the art and craft of building and fabricating in stone, clay, brick , or concrete block. Construction of poured concrete , reinforced or unreinforced, is often also considered masonry. The art of masonry originated when early man sought to supplement his valuable but rare natural caves with artificial caves made from piles of stone. Circular stone huts, partially dug into the ground, dating from prehistoric times have been found in the Aran Islands , Ireland.

By the 4th millennium bce , Egypt had developed an elaborate stonemasonry technique, culminating in the most extravagant of all ancient structures, the pyramids. The choice of masonry materials has always been influenced by the prevailing geological formations and conditions in a given area. Egyptian temples, for example, were constructed of limestone , sandstone , alabaster, granite , basalt, and porphyry quarried from the hills along the Nile River.

Another ancient centre of civilization, the area of western Asia between the Tigris and Euphrates, lacked stone outcroppings but was rich in clay deposits. As a result, the masonry structures of the Assyrian and Persian empires were constructed of sun-dried bricks faced with kiln-burned, sometimes glazed, units.

An essential introductory guide to all aspects of permeable paving for designers, developers, planners, regulators and all those involved with development. This edition reflects the latest thinking based on experience from long-term usage and reviews recent innovations and developments. This enhances the high albedo — or heat reflectance — offered by concrete block or flag paving generally, compared with asphalt.

Multifunctional Sustainable Drainage. It simply allows water to pass through joint filling material in gaps between concrete paving blocks or flags into the underlying permeable sub-base. Here, it is stored and released gradually to help prevent flooding. At the same time, many pollutants are substantially removed and treated within the pavement itself. Guidance on spatial planning, structural and hydraulic design, specification, detailing, construction and maintenance of concrete block permeable pavements.

This document brings together a variety of construction details, demonstrating best practice to make permeable paving and SuDS robust and durable over the long-term.

Waukesha County. A concrete block foundation in need of repair – notice the cracking occurring at the mortar joints. The foundation of your historic house or building could be made of concrete masonry building blocks, which were once referred to as cinder blocks. Most of the problems that occur with concrete foundations result from a lack of maintenance. You might be able to solve some of the typical problems you will face with your concrete block foundation on your own, while other problems will require the expertise of a professional mason.

Excessive moisture may be the cause of this concrete block foundation cracking at the mortar joints as well as the paint peeling. Source: Bob Yapp. Concrete blocks have been used in one fashion or another since early Roman times. The concrete blocks used in Wisconsin up to about often had coal clinkers — the cinders or waste created from burning coal — added to them.

Modern concrete blocks have sand and gravel added to them. By , cheap Portland cement was in wider use, and it greatly strengthened concrete blocks. Some early versions of concrete block were entirely solid. Today, concrete blocks are made with hollow voids, but they are designed to carry heavy loads.

Breeze blocks are having a moment in the sun. Having been painfully hip in the architecture of the s and 60s, they were used so extensively, in both houses and commercial buildings, that they became ubiquitous anywhere in the world where it was hot — including throughout Australia. While particularly associated with a beachy, holiday feeling — Gold Coast motels, houses in Palm Springs — they were really so widely-used that they can still be found pretty much everywhere.

But after that postwar high point, they fell drastically out of favour, and languished for the next fifty years, built into the walls and gardens of our youths, widely loathed and reviled for being ugly and out of date.

Mortar is a workable paste which dries to bind building blocks such as stones , bricks , and concrete masonry units , to fill and seal the irregular gaps between them, and sometimes to add decorative colors or patterns to masonry walls. In its broadest sense, mortar includes pitch , asphalt , and soft mud or clay, as used between mud bricks. The word “mortar” comes from Latin mortarium , meaning crushed.

Cement mortar becomes hard when it cures, resulting in a rigid aggregate structure; however, the mortar functions as a weaker component than the building blocks and serves as the sacrificial element in the masonry, because mortar is easier and less expensive to repair than the building blocks. Bricklayers typically make mortars using a mixture of sand , a binder , and water. The most common binder since the early 20th century is Portland cement , but the ancient binder lime mortar is still used in some specialty new construction.

Lime, lime mortar and gypsum in the form of plaster of Paris are used particularly in the repair and repointing of historic buildings and structures so that the repair materials will be similar in performance and appearance to the original materials. Several types of cement mortars and additives exist. According to Roman Ghirshman , the first evidence of humans using a form of mortar was at the Mehrgarh of Baluchistan in the Indus Valley, Pakistan, built of sun-dried bricks in BCE.

These ASTM standards contain minimum requirements that assure properties necessary for quality performance. These requirements include items such specified component materials, compressive strength, permissible variations in dimensions, and finish and appearance criteria. Currently, seven ASTM standards apply to units intended primarily for construction of concrete masonry walls, beams, columns or specialty applications see Table 1.

The letter and first number of an ASTM designation is the fixed designation for that standard. The number immediately following indicates the year of last revision i. A date in parentheses after the last revision date is the reapproval date. Because significant changes can be introduced into subsequent editions, the edition referenced by the building code or by a project specification can be an important consideration when determining specific requirements.

Also note that it may take several years between publication of a new ASTM standard and its subsequent reference by a building code. Code officials will commonly accept more current editions of ASTM standards than that referenced in the code, as they represent state-of-the-art requirements.
