Testing of hardened concrete is one of the most important to be performed at the site to check the strength and durability of concrete. It plays an essential role in controlling and confirming the quality of concrete works. Conventional concrete testing methods such as tensile strength, compressive strength, flexural strength etc. need strict supervision and…
Damp Proofing in a construction is a technique of preventing moisture from entering the interior of the structure to prevent weakening or decomposing of construction materials (i.e. weakening of bricks due to overwater absorption and oxidation of steel results in the development of cracks in walls). It is basically a technique of making the outer…

Seasoning is the process of reducing the moisture content by drying under controlled conditions a nearly as possible at uniform rate from all parts of timber in order to prevent the timber from posse fermentation and making suitable for use. A well-seasoned piece of timber contains moisture content in the range of 10-12%. The objectives…
Lime is an ancient engineering material used as a cementing material. The Egyptians and Romans made remarkable application of this material for various constructional purposes. Even in India, lime has been a popular engineering material which was used as a binding material in various structures such as palaces, forts, monuments etc., some of them still…
What is Concrete? Concrete is a mixture of cement, sand, crushed rock and water which when placed in the skeleton of forms and allowed to cure, becomes hard like a stone. The subject which deals with the fundamental principles of concrete is known as Concrete Technology. The practical utility of Concrete Technology enables the civil…
Rocks are huge mass substance that are formed inside the earth’s crust due to rapid heating and cooling of lava. Rocks do not have any specific shape or chemical composition but are mixtures of two or more minerals. The rocks are classified into three groups i.e. Geological, Physical and Chemical classification. In this article, classification and…
Cement is a fine powdered material which is used in construction as a binding material. Due to its binding property it is extremely responsible for strength and durability of structure. Therefore, it is important to use best quality cement to maintain structure quality. To identify whether cement is fit to use in construction, various laboratory…
The cement is a fine powered material used in construction as binding material. Cement is a product obtained by burning a well proportioned mixture of Silicious, Argillaceous and Calcareous materials and crushing the same into a fine powder. Cement usually means OPC (Ordinary Portland Cement) in civil engineering. Ingredients in cement : Lime …
Brick is a product made of burnt clay or mixture of sand and lime. It is generally used for constructing walls, columns, roofs, paving floors etc. Bricks are available in different sizes depending on type of construction. However, the common size of brick is 19 x 9 x 9 cm. Ingredients used in making of brick…
