CIVIL ENGINEERING MATERIALS (CE 103): Timber

Timber in Construction

Welcome to Chapter 7 of Civil Engineering Materials (CE 103). This chapter delves into Timber, one of the oldest and most versatile construction materials known to humanity.

In this module, we will explore the lifecycle of timber from tree to structural element. The curriculum covers the growth and structure of trees, the classification of wood into hard and soft varieties, and the critical process of seasoning to ensure dimensional stability.

We will also examine common defects in timber, methods for its preservation against physical and biological deterioration, and the wide array of commercial timber products such as plywood and laminated boards. Finally, the chapter highlights Bamboo as a sustainable alternative with unique mechanical properties.
