ARCH 3007 Exam 3 - Brick / Masonry

Constructed of materials used by masons: brickwork, concrete block work, and stone work

A skilled worker who builds by laying units of substantial material such as stone or brick

Excavated clay, shaped, dried, stacked, fire resistant, small in scale

Likely to crack during drying

Easy to install and stack

Dimensioned to fit human hand

Extruded and cut or pressed in molds; then fired in kilns

Laid in position for visual and structural reasons

Parts of brick

Laid in position for visual and structural reasons pattern is called a bond

Cushions the units giving them full bearing

Seals units to keep out water/wind

Bonds units into monolithic structure

Affects the finish or overall appearance

Occupies about 20% area

Mortar ingredients

Mortar in joints

Mortar behind, ground in joint

Scrape out and replace external layer of mortar

Average thickness is about 3/8”

Beaded joint

Larger than brick, made from concrete

Vibration of stiff concrete mix into metal molds cured at an accelerated rate with steam

Clear, heat absorbing, reflective

Types of bonds

Veneer vs. solids masonry

Dimensions / 8” = X or X.5

Running Bond - the simplest pattern

Common Bond - similar to running bond but a head course at every 5th, 6th, or 7th course

Stack Bond - no overlapping units, longitudinal reinforcement

Flemish Bond - each course consists of alternating headers and stretchers

Common Bond - every 6th course is composed of Flemish headers

English Bond - Pattern consists of alternating stretcher and header courses
