describe the three types of silicosis that can affect mason tenders; describe the four types of cement contact dermatitis that can affect mason tenders; describe the correct procedure for mixing water with acid; describe the types of Personal Protective Equipment (PPE) used by mason tenders and the hazards each type of PPE protects against; describe appropriate first aid procedures when given a description of an injury on a masonry construction project; describe the purpose of reinforced masonry construction; describe the functions of reinforcing steel and grout; describe the four types of reinforced masonry walls; describe how each type of wall tie and anchor is used in a masonry wall system; explain the purpose of flashing; given pictures or graphics of masonry construction or situations involving the installation of flashing, identify the areas where it is typically used; describe the purpose of control joints; given pictures or graphics of masonry construction or situations involving the installation of control joints, identify the areas where they are typically placed; explain the importance of accurately estimating masonry materials on a job; identify various types of brick and block; describe nominal dimensions in regard to estimation amounts of block and/or brick; calculate estimates for block and brick using the square foot method; calculate estimates for block and brick using the conversion method; estimate the amount of block and/or brick needed for a given project; given information on the layout (dimensions) and type of material used to construct multiple and various masonry projects, estimate the amount of block and/or brick needed for each project; explain the properties of masonry mortar; describe the characteristics of Portland cement mortars and masonry cement mortars; describe the seven types of mortar admixtures and their purposes; describe the four types of mortar mixing systems; given the appropriate materials and equipment, properly set up a power mortar mixer and mixing area; given the appropriate materials and equipment, accurately and correctly mix a batch of mortar, both manually and with a power mixer; given the appropriate materials and equipment, accurately and correctly mix a batch of colored mortar (both manually and with a power mixer); given the appropriate materials and equipment, accurately and correctly mix, place, and consolidate a batch of fine grout and coarse grout; given the appropriate materials and equipment, safely clean a power mortar mixer and mixing area; identify five hand tools that are commonly used when stocking block and/or brick; stock the materials necessary for the masons to begin construction on a masonry wall at ground level; demonstrate the ability to stock masonry materials on a scaffold for a masonry wall under construction; estimate the approximate amount of brick and block needed to complete a given section of wall; estimate he approximate amount of brick and block needed to complete a given section of wall; identify the proper personal protective equipment (PPE), tools, and equipment necessary for a mason tender; calculate the “cuts” necessary to maintain the bond in a masonry wall when given a set of masonry wall designs; describe the tasks required of a mason tender when performing housekeeping duties, equipment maintenance and shutdown; demonstrate the ability to “work the line” when given the setup, masons, and materials needed to construct a masonry wall by supplying and maintaining a consistent and quality mortar to the masons and correctly stocking materials and supplies as they are used; list the reasons mortar loses strength in cold weather; describe the types of materials that must be used during most cold-weather masonry construction; describe how masonry materials should be stored, heated, and placed during cold weather construction; explain the problems that may be encountered when constructing masonry in hot weather; list eight ways to reduce the effects of hot weather on masonry construction; explain five precautionary measures that can be taken to keep masonry walls clean; list three categories of cleaning failures; describe the different types of cleaning problems (i.e., efflorescence, white scum, green stain and brown stain); explain how cleaning failures can be prevented and cleaned; describe the proper method for cleaning a section of masonry wall using the following methods: bucket and brush hand cleaning, pressurized water cleaning and abrasive blasting; properly set up a stationary masonry saw; demonstrate the procedure for mounting and “ring testing” both a diamond blade and abrasive wheel; demonstrate how to maintain and clean a stationary masonry saw; perform the following types of cuts with a masonry saw: step cut, chop cut, cutting-head-positioned-down cut, and angle cut; demonstrate the proper donning and use of the personal protective equipment (PPE) needed when operating a masonry saw; describe at least 10 safe work practices that should be followed when operating a masonry saw; identify when masonry walls need to be braced; identify the components of a wall bracing system; calculate the maximum spacing between braces; identify the tools and materials needed for bracing a masonry wall; install all necessary bracing on a masonry wall under construction correctly and efficiently according to course guidelines; describe the three basic types of plaster; describe the various types of bases to which plasters can be applied; describe scratch coat, brown coat, and finish coat; describe the purpose and desired properties of both water and sand/aggregates when mixing gypsum plasters and stucco; and correctly and accurately proportion and mix gypsum base coat plaster, veneer plasters, and stucco with a mechanical machine and by hand.

Instruction: 

Course 1 and 2: Major topics include: different types of masonry construction, masonry unit identification, material estimation and stocking procedures, the mason tender’s general duties, and the typical work that laborers perform on masonry construction job sites. Proper mortar mixing techniques, the use of admixtures, and the effect of weather on mortar are also addressed. Additionally, these courses provide instruction on how to safely brace newly erected masonry walls, present safety and health issues of the mason tender including silicosis, and address the use of proper personal protective equipment.

Credit recommendation: 

Course 1 and 2: In the lower division baccalaureate/associate degree category, 5 semester hours in Introduction to Masonry Technology (4/16).  NOTE: Both courses must be successfully completed to gain access to credit recommendation.
