Study Notes

Masonry Construction

The primary material used in masonry is brick.
The simplest and most ancient building technique is rubble masonry.

Historical Context

The historical Sultan Hassan is located in Egypt.

Materials

Stone is a durable, compression-resistant, and structurally effective material.

Ancient Architecture

The King Zoser complex was built around 2650 BC.

Types of Masonry

Rubble masonry is a type of masonry that is specifically mentioned in the text.

Mortar in Masonry

The function of mortar in masonry construction is to bind bricks or blocks together.
Type (M) mortar is suitable for masonry construction below grade and subject to high lateral or compressive loads.

Brick Formation

The three major methods used for forming clay bricks are extrusion, pressing, and molding.
Terracotta Clay Bricks are formed using the extrusion method.

Masonry Tools

The measuring tape is used in masonry construction to take precise measurements.
A Mason’s line is used to ensure that the masonry work is straight and level.
A Plumb bob is a weight attached to a string used to ensure vertical alignment.

Bricks

A Facing (Veneer) Brick has dimensions of 215 x 102.5 x 65 mm.

Mortar Types

Type (O) mortar is distinguished from other mortar types by its high lime content.
Type (S) mortar is distinguished from Type (N) mortar by its higher compressive strength.

Waterproofing

The primary purpose of waterproofing in construction is to prevent water seepage.
The surface must be cleaned and prepared before applying waterproofing materials.
Bitumen is mentioned as an example of a waterproofing material.
Expansion joints must be sealed during surface preparation for waterproofing.
Water stops are used to prevent water seepage through joints.
Waterproofing protects against water damage and structural degradation.
Any leakage points must be addressed before starting the insulation process in waterproofing.

Building Insulation

The primary purpose of building insulation is to reduce heat transfer.

Dampness in Buildings

Common causes of dampness in buildings include poor waterproofing, inadequate drainage, and high groundwater levels.
Dampness can cause structural damage and degradation of building materials.
The orientation of a building in relation to the sun and wind can affect dampness.
The rise of ground moisture around a building can be caused by poor site drainage.
