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.
