Roofs can be defined as the uppermost part of a building covered with a structural covering for protection against the weather. It is beautiful to have a roof with different shapes & geometry and covered with a variety of materials. Roofing materials must be chosen and designed based on the conditions of the climate and the surface to be covered Requirement of a Roof The type of roof for a building should be chosen after considering the climatic conditions as well as the material availability. In order for a roof to be well planned, it must meet the following requirements.…

Comparison of Ordinary Portland cement And Pozzolana Portland cement

Comparison of Ordinary Portland cement And Pozzolana Portland cement: Ordinary Portland Cement (OPC) is the most popular cement in the world, but Portland Pozzolana Cement has also gained popularity in recent years. OPC is the basic component used for concrete, mortars, stucco, and other construction materials that require cement. It is classified as hydraulic cement, meaning that it both hardens as a reaction to water but also becomes waterproof once it dries. In this article, you will learn about the Comparison of Ordinary Portland cement And Pozzolana Portland cement Comparison of Ordinary Portland cement And Pozzolana Portland cement Definition Ordinary…

10 Different Types of Stone used in Building

Types of Stone: In this article, you will learn the different types of Stone and their Applications, Compressive Strength, and other Properties. 1. Chalk                 It is pure white limestone and easy to form a powder. It is a sedimentary type of work. Chalk is used as a material for the manufacturing of Portland cement. 2. Basalt and Trap                 There are three types of Igneous rock i.e. Intrusive, Hypabyssal, and extrusive rock. A basalt and Trap rock comes under an extrusive rock. It is hard and tough in nature. The compressive strength of   Basalt and Trap range from…

Storage of Construction Material- Steel Bars, Cement, Bricks & Aggregate At Construction Site

Storage of Construction Materials (Steel Bar) at Construction Site. As we know that steel bars cover 25 -30% of the overall cost of the building so it is very crucial that steel bars must be handled and stored with precaution on the site. There are different processes or operations where laborers need to take care of steel bar such as unloading, Stacking, Cutting, Bending, Fabrication, etc. Reinforcement has the capability to resist lateral forces and provide strength and ductility to the buildings, so it is very necessary that all these loading and unloading operations should be done properly on site.…

7 factors that affect the workability of Concrete

The ease with which concrete is placed, compacted, transported, and finished without segregate is known as workability of Concrete. Concrete has good workability gives good strength and durability. It is the property of fresh concrete. The factors that affect the workabilities of concrete, such as Water content, Mix proportions (Aggregate /cement ration), Size of aggregates, the shape of aggregates, the surface texture of aggregates, grading of aggregates and use of admixtures. Factors Affecting Workability of Concrete Water content The workability of concrete is directly proportional to water content. As water content increases, workability also increases. Increase in water content in…

11 Important Points to Remember For Civil Engineer About Coarse Aggregates.

In this article, I have explained 11 Important points About Coarse Aggregate. It comprises of Definition of Aggregates, Sieve used for Aggregates, Fineness Modulus, Specific Aggregates, Types, and Field Test of Coarse Aggregates. The following are the 11 Important Points to Remember for Civil Engineer about Aggregates. Definition of Aggregates. Coarse Aggregates are the particles which are retained on 4.75 mm sieve. Coarse Aggregates are larger in size as compared to fine aggregates. It obtained by the processing of igneous rocks such as pumice, scoria, and tuff. Some of the most common natural aggregates are silica sand, gravel, crushed lightweight…

Clay                        less…

Bricks: Properties Composition and Composition of Good Quality of Bricks

Bricks are one of the building material which is used to construct the wall, foundation, etc. It is widely used at present in Reinforced concrete structures because of its good compressive strength, durability, low cost, and availability, etc. It is manufactured by molding clay in rectangular blocks of uniform size and kept for drying and in the end, burnt all the blocks. Standard Size of Modular Bricks without mortar = 190 mm x 90 mm x 90 mm. Size of Modular bricks with 10 mm thick mortar = 200 mm x 100 mm x 100 mm. Properties/ Characteristics of Good…
