CMP 210 Exam 2 2022/2023 with 100% correct answers

reinforced masonry used then flexural, compressive, and shear stresses exceed those permitted for partially or unreinforced masonry cavity wall construction generally used for exterior walls because they can control moisture penetration and be insulated expansion joints create space between adjacent parts of masonry construction and permit a limited amount of movement control joints provide tension relief between parts of masonry walls that may change from their original dimensions (control where crack occur) weep holes opening left in the mortar joint - used to direct moisture out of the building tooled joints best for resisting leakage weathered, concave, or v-joints arches form of curved construction used to span an opening, usually consists of wedge-shaped blocks called voussoirs rubble stone found naturally in irregular shapes and sizes ashlar type of masonry that uses units cut into squared shapes dimension stone large sqaure blocks flashing placed wherever there is a break in the cavity thin materials impervious to water needed to prevent penetration and provide drainage surface clay shale and fire clay, reside near surface and is strip mined shales clay subject to high pressure causing it to be hard fireclays found at deeper levels and have more uniform physical and chemical properties, can withstand higher temps, used in fireplaces calcareous clays 15% calcium carbonate and have a yellow brown color when burned non-calcareous clays contain silicate of aluminum, feldspar, and iron oxide, takes a red/salmon color when burned stiff-mud process method of forming brick, passes clay of 12-15% moisture through a vacuum that removes air pockets soft-mud process used when clay has more than 15% moisture, burns bricks until they've reached desired level solid amasonry (brick classification) if they have cores whose area does not exceed 25% of the gross cross sectional area of the brick modular bricks actual size plus a mortar joint can be assembled on a standard unit or model hollow clay masonry
