Stamped Concrete

This post is providing a brief idea about the Civil Engineering Topic Stamped Concerete. Stamped Concrete is the process of adding texture and color to the concrete to make it as a resemble stone, slate, brick, cobblestone and many other products found in the nature including wood, shells, fossils, and many more things. This limitless array of the possibilities combined with a great durability and lower cost than the natural products makes the Stamped Concrete as an easy choice for new construction and renovation projects.

The installation consists of the pressing molds into the concrete while the concrete is still in its plastic state. Color is achieved by using the Color Hardeners or Dry Shakes , Liquid Releases or Powder, Acid Stains or Integral Colors. All these products may be combined to create even more intricate designs.

Decorative Concretes

This Civil Engineering Topic is regarding with the Decorative Conceretes. From the last many years, concrete has been used as a simple, effective & low cost surface for all sorts of areas ranging from car parks to the drive ways to commercial freight yards. However, the one factor you rarely hear being praised is its looks. Techniques to improve the aesthetic appeal of the monolithic concrete pavements have been around since the fifties, notably in North America where concrete is possibly the most popular surfacing for patios, drives and 'yards', and in southern hemisphere, particularly Australia. However, it is the only since the mid 1980s that many of these techniques found their way to the North-west European paving market. Decorative concretes have been used to the dramatic effect in the new structural developments such as Trafford Centre in Birmingham, UK, Basilica of Yamoussoukro on Ivory Coast & the new European Parliament building. Dramatic effects are not only achieved in large structures though. Coloured concrete is just as effectively used in architectural pavements, paving stones and the internal flooring Undoubtedly, the most popular prettifying technique we see in the UK and Ireland and other western countries are Pattern Imprint, sometimes known as ‘Stamped’?’Imprinted' or 'Textured' concrete. From a sluggish start at the back end of the 1980s this technique has slowly but surely grown in popularity and now attracts a reasonable level of the interest, in both residential and commercial markets. In the recent years, refinements and developments of this technique have emerged and we now have stencilling techniques, high-strength textured overlays.

Self Compacting Concrete

This Civil Engineering Topics is discussing with the Self Compacting Concrete. Concrete is one of the most used construction material in the world and if correctly composed, it can be vary durable and thus save considerable society resources in the maintenances cost. Self compacting concrete is one of the subjects of concrete technology. The various investigations have been carried out and hence the concrete has been used in practical structures. Here we are providing a brief introduction to self compacting concrete which is also known as SCC is given. The definition and motivation for the development of Self compacting concrete have been discussed. The Self compacting concrete has some advantages over the normal concrete and also some disadvantagesover the normal concrete. An approach has been made to study the various aspects of the Self compacting concrete, such as types of Self compacting concrete, materials used and testing methods, in detail. This Civil Engineering paper also touches the economical considerations, applications and future development of the Self compacting concrete. A concrete that places itself - 'SCC’ A well-proportioned Self compacting concrete can flow under it’s own weight through and around congested reinforcement filling forms completely and producing a void free mass with no vibration and without segregation problems. When large quantity of heavy reinforcement is to be placed in RC member it is difficult to ensure that the formworks get completely filled with concrete that is fully compacted without voids of honeycombs. This problem can now be solved with SCC. SCC is placed or poured in the same as ordinary concrete but without vibration. It is very fluid and can pass around obstructions and fill all the nooks and corners without the risk of either mortar or other ingredients of the concrete separating out. At the same time there are no entrapped air or rock pockets. This type of concrete mixtures does not require any compaction and it saves time labor energy. The surface finish produced by Self compacting concrete is exceptionally good & patching will not necessary. This concept of Self compacting concrete was followed by a major European Research & Development projects. Self compacting concrete has been successfully used in France, Denmark and Netherlands and UK apart from Japan. It is gaining wide acceptability because no noise pollutions there and the construction process is safer and more productive. So ny these we can say that Self compacting concrete is a very good topic in the Civil Engineering.

Advanced Construction Materials

A research on the advanced construction materials has given a push by many factors. In late eighty's, the aerospace industry has seen a steady decline; alternative use of new materials develop for aerospace industry is made possible to construction sector. Exotic materials such as advance polymers & high performance carbon fibre sheeting are researched upon to develop their potential use in the construction of the corrosion free buildings.
The advanced materials are looking on as next generation materials for high techbuildings. Materials that has been researched not only enhances the durability of buildings, but they also have ability to reduce the manpower usage, reduce or eliminating corrosion, and enhancing strength of the structural members. One of new materials which is being rapidly developed & applied is the use of continuous fibres in the construction. Continuous fibres are widely used in the retrofitting and strengthening type of works. Fibres could be impregnat in the resin at factory to produce stiff fibre reinforce polymer plate or they could be soaked in a resin just prior to application at site. Fibre Reinforce Polymer (FRP) utilises the high performance fibres such as the carbon aramid, kevlar and the other glass fibres encapsulated in the resin matrix. This technology has been developed to an alternative to the conventional steel reinforcement for using in the concrete structure primarily for avoiding the corrosion problems associated with the steel.Now, Fibre Reinforce Polymer can be used to increase or enhance flexural & shear strength of the slabs, Columns, Joints and the Slabs.
