Other masonry unit types include cast stone and calcium silicate units. This has good bond qualities and good resistance to water penetration. Has a higher proportion of cement and subsequently can have increased shrinkage of the mortar. These materials expand in warm temperatures and contract in cold temperatures.
Masonry Wall Systems
This air can achieve a relatively high vapor pressure relative to the interior. Although this horizontal reinforcement improves the strength of the masonry, particularly for horizontal spans, but also serves to control shrinkage cracking. These systems can be effective in reducing the amount of water penetration into the masonry; however, they should not be relied upon to eliminate water penetration. The fire resistive characteristics are based on the thickness of the masonry. Because of the mass, masonry wall systems can provide better sound insulation than lighter wall systems such as metal panels.
