Newer materials, less costly to prepare and use, have caused resurgence in the popularity of plaster, but the traditional skills needed remain time-tested. You will learn their various names and where the material should be used in a wall.
This course will focus on preventive maintenance to stop any further damage of the masonry structure. There are broad variations in construction materials and technology, shape, and the number of stories. Bricks are available in a wide variety of colors and types. The results and cost of matching bricks varies greatly with the effort spent. The course is divided into three modules, each covering an essential aspect of the trade: the history of masonry, tools and equipment, and measurements and drawings used by masons.
This video will introduce you to the basic concept of masonry. This is an introduction to a series covering the basics of masonry.Masonry Pages – Masonry Intro
Carroll did an excellent job; he was both friendly and efficient. These ceremonies were desinged to test men, to allow only those who were worthy to be admitted. Our ceremonies are somewhat the same, less physical in nature, and more spiritual in form. Operative masons back then formed groups with structures similar to ours today. They were the best at their craft, and they kept secret their methods of building. Must check shear capacity of tie- columns! Students will learn what the different strengths of cement and where they should be used. Techniques include firewall construction, brick veneering, porch/ patio and step construction, and proper preparation for varying weather conditions. Buildings of this type range from cultural and historical landmarks, often built by highly skilled stonemasons, to simple dwellings built by their owners in developing countries where stone is an affordable and cost-effective building material for housing construction.
Masonry consists of building structures by laying individual masonry units (brick, concrete block, stone, etc). Over time, even bricks made by the same brickyard and bearing the same name do not match exactly. Different mortar types, made from different ingredient mixtures, are used for different applications. This is an introduction to a series covering the basics of masonry. In this video, you will learn about masonry. Today, with the world’s population increasing at unprecedented levels, more people need homes to live in, as well as infrastructure to support their lifestyles. This means that there is a higher demand for masons than ever before. The ancient craftsmen were very skilled, and their craft was considered to be indispensible to the welfare of both church and state.
For this reason, they were not placed under the same restrictions of other workers – they were “free” to do their work, travel and live their lives in a manner which befitted their importance.
Most workers were under bond to the owners of the land on which they worked. These men did not necessarily want to build buildings, they wanted to belong to the organization. This practice probably originated when some of the people for whom craftsmen were working asked to be admitted and the practice grew with time.
Sometime in the late seventeenth century, we believe the accepted masons outnumbered the operative masons, and we became a speculative organization rather than operative one.
We are not a secret society, but we are a society with secrets. Our secrets, maintained through a sense of tradition, are very few few in number and deal mostly with the obligations and modes of recognition.
These requirements have been handed down by word of mouth for centuries. There are numerous books on these subjects which are available to the public. Masonry seeks only to unite men for the purpose of brotherhood – not religion. An avowed athiest would not profess this belief and thus would not be admitted. Generally, religion and politics should not be discussed in lodge, and there are very good reasons not to discuss these topics. There will also be subjects concerning the lodge’s business that should be discussed. There are three reasons that could explain why this term originated. How can a candidate prepare himself for initiation? To receive the greatest benefit from the initiation ceremonies, a candidate should first prepare his mind for its reception. He should not be apprehensive and should enter the lodge with the attitude which will enable him to appreciate the serious and solemn ceremonies through which he will pass.
The methods used in teaching are allegory and symbolism and will be new and unusual to the candidate. These methods have been used for almost three centuries and have not changed very much since they were originated. Is there any horseplay or hazing during the ceremonies? The rituals are serious and solemn, and are to teach spiritual lessons with great dignity. The candidate should have no apprehension about entering a lodge. He is always entering a society of freinds and brothers, where he will be treated with dignity and decorum at all times. Must check shear capacity of tie- columns! Inadequate wall density (less than 1% per floor) 84. All mix quantities given below are volume proportions (as opposed to weight proportions). Low lift grouting is a simple method of placing grout at scaffold height (prior to building the next lift of scaffold) or bond beam height.
Vertical rebar, if required, are often placed in the cores after grouting and stirred to help consolidate the grout. One difficulty with low lift grouting involves the lifting of the next courses of concrete masonry units over the rebar dowels that project after each grout lift.
There should be a method agreed upon for filling wall voids that assures the grout gets all the way to the bottom. Or perhaps structural loads from wind, snow, or vibration get movement started. Steel horizontal joint reinforcement also can be used at 8″ to 24″ on center and laid directly in the horizontal masonry joint.
Control joints are used to relieve masonry tensile stresses and allow movement to occur. If you are somewhat new to construction, take some time and review this excellent resource. Think about temporary bracing of masonry walls as a structural engineer would. Make sure mortar doesn’t get used when grout is specified. Understand where masonry control joints must be placed before any work begins.
