Southeast Concrete Masonry Association SCMA has created a Concrete Masonry Academy designed to provide monthly education webinars on a variety of topics for all industry professionals at no cost. The New Simplifying Masonry Series is designed to provide the professional community as well as the concrete masonry community a more in-depth education of the various elements of concrete masonry.

Please note that the webinars are indicated below if they are AIA-registered and a certificate of attendance will be provided upon request. If you attend both presentations on the same day, you will be recorded as attending only one as they are the same presentation tailored for different audiences. Starting in July, Block will cover a series of 19 training sessions on concrete masonry. Please note that the Masonry Audience includes masonry personnel with years experience and masonry contractors.

This article series provides a photo guide to determining the age of a building by examination of the architectural style of construction or the building materials and components that were used in the structure.

Here we list some helpful clues to answer the question “how old is the house? The age of a building can be determined quite accurately by documentation, but when documents are not readily available, visual clues such as those available during a professional home inspection can still determine when a house was built by examining its components, building materials, even nails, fasteners, and types of saw cuts on lumber.

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.

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.

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 present invention relates to the concrete protection piece of monobloc cast, the safeguard structure with in Yu Haiyang and the River Engineering to resist wave and current, also relates to the mould that is used to make this concrete block. The technical characterstic that this artificial piece will satisfy is: stable and firm in water. Except these technical characterictics, the designer’s of concrete block purpose is to reach outside desired stability of use and the fastness, reducing by a needed concrete amount of definite overcoat.

For this reason, the designer adjusts the size and the angle of concrete block configuration part, so that increase the space between the staggered concrete block. The designer tends to change the corner angle of concrete block or the size and dimension of body, so that the connection degree is higher between the concrete block, and space each other is bigger, for this point, the concrete block that document US-A of the eighties can be introduced and the taller and thinner concrete block of being introduced by document US-A more recently compare.

In addition, in order to reduce the used concrete volume of each concrete block, the shape of concrete block also is partial to tall and thin. It is short to make concrete block become the long trunk of four limbs like this, has weakened the intensity of corner angle. The concrete block that obtains has like this been saved a considerable number of concrete.

But its fastness has descended, and in the operating period, can cause overcoat to start a leak because of the broken slump of concrete block, makes the part of ocean and River Engineering come out, and becomes the origin of damage. Document NL-A has introduced a kind of concrete protection piece of building, and its objective is the fragility that the device of the maximum impulsive contact force that is applied to it by other piece that reduces around the concrete block comes the compensating concrete piece.

The solution of being introduced is, adds a pitch or rubber or concrete–rubber combined surface course on the concrete protection piece of building, and its rigidity is lower than concrete protection piece itself. Like this, damp impacts between the concrete block. Also mention in the file,, the boss or the block of wood, rubber or concrete system can be arranged in the surface course, make surface course lower than the concrete block rigidity that it covered for same purpose.

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.
