Volume Change and Creep of Concrete

R.F. Feldman

The resistance to deformation that makes concrete a useful material means also that volume changes of the concrete itself can have important implications in use. Any potential growth or shrinkage may lead to complications, externally because of structural interaction with other components or internally when the concrete is reinforced. There may even be distress if either the cement paste or the aggregate changes dimension, with tensile stresses set up in one component and compressive stresses in the other. Cracks may be produced when the relatively low tensile strength of the concrete or its constituent materials is exceeded. (Read more..)

The ‘science’ of civil engineering deserves an artistic approach

by Sadek Owainati

[More Images] Engineering is mainly classified as an ‘applied science’ subject, but more often than not, engineers are asked to produce ‘innovative designs’ and propose ‘creative solutions’. This suggests that engineers need to be both scientists and artists. (Read more..)

Duct Cleaning

By Chris Welsh
For allergy sufferers life can be a never ending quest to discover the causes of those headaches, congested sinuses, itchy eyes and general irritation that plagues them. Medication, weather, commercial products and personal habits are all scrutinized, put under the microscope to determine if they contribute in any way to the allergic reactions. (Read more..)

Sheet piles offer an economical solution

by Dhairya Narayan Jha

Steel sheet piles are long structural sections with interlocks which form a continuous retaining wall. To retain soil or water in most cases, sheet piles have been used for all kinds of temporary and permanent retaining structures being extensively used for quay walls, cofferdams, tunnels, underground parkings, shoring for foundation pits, sewerage and drainage works, micro tunnelling, to name a few.

What is Die Casting?

By Chris Welsh
Wrenches, toy cars, parts for watches and blenders, the inner workings of many a mechanical marvel; what do they all have in common? They were die cast, a process of “rubber stamping” products in a uniform manner which typically results in high production or identical or nearly identical products. A die cast car, for example, can be made by the dozens or hundreds at a time, producing high volume yields with few, if any, quality control concerns. (Read more..)

Types of Ceramic Tile

Ceramic tile has been used for centuries and offers consumers more options in color, texture, pattern and overall beauty than most other floor covering materials. With new manufacturing techniques today’s ceramic tile designs are virtually indistinguishable from natural marbles, travertines, slates and other stone products. Glazed ceramic and porcelain tiles are great choices for bathrooms, kitchens, foyers, sun rooms and great rooms. (Read more..)
