is a popular construction material, often used alongside concrete to create impressive and long-lasting buildings. Its versatility, sustainability and flexibility are some of the main reasons for its use, as well as being a very cost-effective material.

CLASSIFYING VARIOUS CONSTRUCTION MATERIALS

is a product that appears in rods and is usually installed as part of a building’s foundation. The distinct design of the rebar which features threads and other symmetrical patterns is designed for concrete applications

is steel that has been metallurgically combined with other metals like manganese, nickel, molybdenum, chromium, or silicon. This is usually done in order to improve the properties of non-alloy steel by increasing hardiness, tensile strength, malleability, machinability, or corrosion-resistance.

can be classified as a subcategory of alloy steel, but with the distinct presence of chromium which is a metal that occurs naturally in the environment. The chromium content is what gives the steel its non-corrosive and non-oxidative properties which make it suitable for a wide range of uses.

refers to a type of steel product that is specifically used to fashion different metals and alloys into shape. Tool steel usually has a better strength rating compared to your average steel pipe, in order to make the tool better for any cutting, fabricating, bending, or machining purposes.

is a ferrous metal made from iron and carbon. It is a low-priced material with properties that are suitable for most general engineering applications. Low carbon mild steel has good magnetic properties due to its high iron content, it is therefore defined as being 'ferromagnetic'.

The purpose of the ______is to arrange various types of soils into groups according to their engineering or agricultural properties and various other characteristics.

is usually referred to as the naturally occurring organic materials found on the earth’s surface. It is mainly made up of minerals, nutrients, water, different inorganic particles, and some parts of plants and animals.

Soil is classified into four types:

is primarily used for industrial purposes. It can be found in the construction industry where it is used to make roads, which is why it is commonly called asphalt in this application. It also has waterproofing and adhesive properties, which makes it a good product for roofing

TYPES OF BITUMEN

The wood of trees that can or will be used for building materials

Classification Based on Mode of Growth: On the basis of molde of growth tress are classified as

These trees grow outward by adding distinct consecutive ring every year. These rings are known as annual rings. Hence it is possible to find the age of timber by counting these annual rings. These trees may be further divided into (1) coniferous and (2) deciduous.

are having cone shaped leaves and fruits. The leaves do not fall till new ones are grown. They yield soft wood.

are having broad leaves. These leaves fall in autumn and new ones appear in springs. They yield strong wood and hence they are commonly used in building construction

is produced from the coniferous cone-bearing tree. This group of trees often have needle-like leaves that are evergreen all year round.

is created from broadleaved trees that shed their leaves after a growing season. Examples of ____ timbers are Oak, Ash and Beech.

Timber Classification

is a composite building material made by combining cement (usually Portland cement), water, coarse aggregates, and fine aggregates.

Also known as “ordinary concrete,” plain concrete is used with a mix ratio of 1:2:4 of cement, sand, and aggregates

is a fast-setting compound of aggregates, cement, and water.

______ into a reusable mold or form creates precast concrete that is cured in a controlled environment to gain the desired strength

is manufactured in factories under controlled operations and transported to construction sites via trucks with in-transit mixers.

is a composite building material reinforced with steel bars placed in the formwork during construction.

is a dark mineral that consists of a mixture of hydrocarbons called “bitumens.” Alternatively known as _____ or “blacktop

common types of concrete

is defined as the ratio of stress to strain of a material.

is the process of segmenting timber's natural variability into groups of set characteristics. ____ allows customers to define what they would like and timber producers the ability to outline what material they have available.
