The slump test is referred to in several testing and building codes, with minor differences in the details of performing the test. In the United States, engineers use the ASTM standards and AASHTOspecifications when referring to the concrete slump test.Concrete Slump Test is a measurement of concrete's workability, or fluidity. It's an indirect measurement of concrete consistency or stiffness. ...

Reinforcement in Slabs and Beams Reinforced Concrete is a concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. If flexural cracks do develop in slabs-on-grade, there is a problem with the subgrade.Bar Bending schedule plays a vital role in finding the quantities of reinforcement in structure.

Reinforcement detailing of a slab is done based on its support conditions. Slab may be supported on walls or beams or columns. Bar bending schedule for slab or steel reinforcement in Slab, I recommend you to learn Basics of Bar Bending schedule and how to adopt concrete cover for different components of a building.

Always lap alternate bars at a time. Always overlap top bars with bottom bars. Maintain sufficient end to end spacing between the laps.Bar bending schedule of the column is described below: The top view shows the length and width of the footing and column.Columns are vertical or inclined compression members used for transferring superstructure load to the foundation.

Columns are essentially required with the primary longitudinal reinforcement and lateral ties to avoid buckling of the primary bars.The functions of longitudinal reinforcement are as follows: To share the compressive loads along with concrete, thus reducing the overall size of the column and leaving more usable area. Maintain sufficient end to end spacing between the laps. Bar Bending Schedule ...

To install Beam Reinforcement Steel needs some particular experience.Reinforced Beams Flexure formula do not apply directly to composite beams because it was based on the assumption that the beam was homogeneous.beam bar bending schedule.

A luffing crane is also a good choice for work sites where two or more cranes are working at the same time. They developed the boom cranes specifically to meet the demands of the industry of greater heights, construction of buildings with little space, etc.

Types of Stairs in Civil Engineering These stairs consist of same sized winders provided at a constant deflecting angle to offer continuous change in direction along within elevation. They radiate around a central newel post and occupy the least space.The stairs are not comfortable as they are full of winders and continuously change the direction. When the available space is too small and numbe...

Bitumen sheet waterproofing is used for the roof covering and for the protection of the foundation.The bituminous waterproofing membrane sheets are overlapped 3 inches at the sides and 6 inches at the ends for proper grip and waterproof joint and block water seepage. Granules Applications.

The installation and dismantling of the tower crane. The installation of the tower crane needs depend on crane or other used tower crane.When referring to cranes and maneuvers that are carried out to assemble, disassemble and hoist a tower crane must comply with the protection and safety manuals To make the crane operational, the ropes must be installed on the crane.

Segregation of concrete is the separation of cement paste and aggregates of concrete from each other during handling and placement wrong mixing water excess too much vibration . Segregation also occurs due to over-vibration or compaction of concrete, in which cement paste comes to the top and aggregates settles at the bottom.

Concrete is the mixture of cement, sand, aggregates and water. Cement concrete is the major building material in the construction industry. It can be easily moulded into durable structural members.Calculate Cement Sand Aggregate and water Quantity in Concrete

The columns help the house to withstand the different loads like buildings own weight, occupant’s weight, the weight of furniture and goods of the house, etc. Columns are very important members of the house, hence special precautions must be taken during column casting.The reinforced concrete column is a pillar that stands as the carrying channel for the structure above it. Thus, expect for imm...
