Load

Load

Load Load A certain amount of force acting on a certain point is called Load. OR Weight per unit area. It has its own importance, the design of the building depends on the amount of it, so as the cost of the building also consists on it, as the amount of weight increase, so does the amount of steel in ...

Benefits of Steel

Steel strucutre-merits

Benefits of Steel Now a days, steel structure are commonly made on the big projects as it saves the numbers persons or the work charge staff, only few skilled person are required, because the members are made in the industries and then assembled on the site. because it will decease the amount of the project in one scene but on the other ...

WC

WC

WC “It is the ratio of water and the weight of the cement used in a concrete mix.” It is denoted as WC = Wt. of water/ Wt. of cement It has an important influence on the quality of concrete produced. A lower WC ratio leads to higher strength and durability but may make the mixture more difficult to place; placement difficulties can be resolve by using plasticizer. The WC ratio is independent of the total ... Read More »

Slump

Slump

Slump The decrease in the height of freshly prepared concrete after lifting the mould of standard dimension is called slump. Types of Slump There are three types of slumps True Slump Shear Slump Collapse Slump Up to 125mm We discard the collapse slump due to the very amount of water present in the concrete mixture. Up to 150mm Shear slump occur due to the lack of cohesion ... Read More »

NDT

NDT

NDT There are two types of both aim at knowing the strength of concrete and determine The quality of concrete respectively, we have so far done distractive test only. The NDT seldom give the exact strength of concrete & distractive test also difficult to made actual structure component for which in-situ NDT, NDT provide information to engineer regarding following properties of the structure material. In-situ strength Properties Durability Density Moisture Content Elastic ... Read More »

Pre-Stress

Pre Stress

Pre-Stress Pre-stress concrete is defined as “The application of compressive stress to concrete member to overcome the concrete natural weakness in tension” Objectives:- Main objective in structural engineering are To economize the construction of structure. To use high strength materials. To improve method of analysis & design. In result of these objectives pre-stress concrete was introduce. Pre-Stress Concrete Members It is structural member in which stress distribution can counter act the ... Read More »

Ingredient of Concrete

Ingredients

Ingredient of Concrete The main Ingredient of Concrete are cement; fine aggregates, coarse aggregates, water and/or admixtures both chemical & minerals. pozzolanic materials like fly ash, ballast furnace slag & silica fumes etc are called as mineral admixtures, where to increase the work-ability and slump for given w/c ratio is known as chemical admixtures. The chemical admixtures should compatible with cement used. Cement and pozzolanic materials are called mineral admixtures and they are grouped as compendious material and ... Read More »
