Here is a list of our top 10 articles of the year :
Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures. So, concrete mix design can be stated as Concrete Mix = Cement:Sand:Aggregates. The concrete mix design involves various steps, calculations and laboratory testing to find right mix proportions.
Compressive strength of concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.
Quantities of materials for concrete such as cement, sand and aggregates for production of required quantity of concrete of given mix proportions such as 1:2:4 (M15), 1:1.5: 3 (M20), 1:1:2 (M25) can be calculated by absolute volume method.
Types of bonds in brick masonry wall construction are classified based on laying and bonding style of bricks in walls. The bonds in brick masonry is developed by the mortar filling between layers of bricks and in grooves when bricks are laid adjacent to each other and in layers in walls.
Concrete slump test or slump cone test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work. Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction.
Knowledge of standard size of rooms and their location in a residential building is important for planning of residential construction project. The room sizes and their location provides spaces for movement, sunlight and natural air for residents. Drawing room or living room is a common, comfortable and attractive place for sitting of family members and to receive friends and guests.
Reinforcement detailing of a slab is done based on its support conditions. Slab may be supported on walls or beams or columns. Slab supported directly by columns are called flat slab. Slab supported on two sides and bending takes place predominantly in one direction only is called One Way Slab.
Broadly there are two ways of harvesting rainwater Surface runoff harvesting Roof top rainwater harvesting Rainwater harvesting is the collection and storage of rainwater for reuse on-site, rather than allowing it to run off. These stored waters are used for various purposes such as gardening, irrigation etc.
Formwork (shuttering) in concrete construction is used as a mould for a structure in which fresh concrete is poured only to harden subsequently. Types of concrete formwork construction depends on formwork material and type of structural element.
Construction tools list for building construction works such as concrete, brick masonry, leveling, wood works, floor works, slab works, brick laying, plastering etc. is provided. Every construction tool is necessary to achieve good results in the whole project. Along with these tools, the workers should also use some safety tools to prevent them from the unexpected accidents.
