Floating slab under chiller

The detail below shows a floating slab under a chiller. Floating slab is a reinforced concrete slab its main function to eliminate the vibration induced by chillers. This reinforced concrete slab is resting on a floating system provided by a supplier. The detail above is for example and guidance only.

Tubular lights foundation

Tubular lights are tubes with an extreme high quality reflection to transfer the sun light through a curved glass to the inside of a building to save electricity consumption and securing a day light for corridors, rooms, halls, etc. From inside the building, tubular lights looks just as simple as a normal light. This is …

Expansion joints

Expansion joints must accommodate movements produced by concrete shrinkage and creep, post-tensioning shortening, thermal variations, dead and live loads, wind and seismic loads, and structure settlements. Concrete shrinkage, post-tensioning shortening, and thermal variations are generally taken into account explicitly in design calculations. Because of uncertainties in predicting, and the increased costs associated with accommodating large …

Proportioning and Mixing Concrete

A CONCRETE MIX is designed to produce concrete that can be easily placed at the lowest cost. The concrete must be workable andcohesive when plastic, then set and harden to give strong and durable concrete. The mix design must consider the environment thatthe concrete will be in; ie exposure to sea water, trucks, cars, forklifts, foot traffic or extremes of hot and …

Pile design

1.1 Pile foundations Pile foundations are the part of a structure used to carry and transfer the load of the structure to the bearing ground located at some depth below ground surface. The main components of the foundation are the pile cap and the piles. Piles are long and slender members which transfer the load …

Concrete Testing

There are two main tests to be done on concrete: The SLUMP test. The SLUMP test shows the WORKABILITY of concrete. Workability measures how easy the concrete is to place, handle and compact The COMPRESSION test shows the best possible strength concrete can reach in perfect conditions. The compression test measures concrete strength in the hardened state. Testing should always be …
