Conventional in situ construction

Conventional in situ twist2.1 IntroductionIn computer architecture and build, in situ refers to construction which is carried out on the building site exploitation raw materials. In-situ is just about commonly a mixture of aggregative (known as builders mix) blended with portland cementum and clean water, that is free of oils, acid and others. Portland cement is made from lime, silica, alumina and gypsum with the raw materials being readily in stock(predicate) end-to-end the country. Aggregate meanwhile is nigh commonly sand, gravel and crushed treasure and constitutes 60 to 75pc of the volume of most concretes. In-situ concrete is strong, durable, stable, readily available and relatively economic in terms of construction and life period maintenance. It is the ideal structural material, in building sites that have difficult access. former(a) qualities that make it an ideal construction medium include the ability to check out of form and shape, the enclosure of space and str ucture in one material, its compatibilty with most other materials, the ability to form integral surface finishes and colour of its compatibilty with most other materials.In-situ concrete structure usually used in industrial and commercial service industry such as school,hospital and hotel.The grassroots form of in-situ concrete structure be columns, beams, walls and floor. Compare that withprefabricatedconstruction, in which building components are made in a factory and so transported to the building site for assembly unlike insitu rule of construction. Conventional building method or in situ construction method, is as well as defined as components of the building that are made at site through the processes of calibre or plywood formwork installation, steel reinforcement, and cast in situ. Conventional buildings are mostly built of reinforced concrete frames. The traditional construction method uses wooden formwork. It is much more costly for construction which includes repu lse, raw material,transportation and humiliated speed of construction time. This system is suitable for a country where incapable labour is limited. There is no heavy machinery or high engineering involved compare to precast method.2.2 Advantages of using in situThe objective of an in situ method is to eliminate and reduce the traditional site-based trades like traditional tincture formwork, brickwork, plastering and to reduce labour content. By using in situ method, revision quite a little be made at the last minute, design can be proceed as the structure is built and the rates of the labor can be fast.2.3 Disadvantages of using in situHowever, conventional in-situ construction method also have their own disadvantages. It will lead to the high amount of wastage compare to precast method. For example, in term of mixture of cement,sand and aggregates. It also require all activities involve high labour and plant on site. Besides,construction is also influenced by the weather an d the reinforcement and formwork tend to be labour intensive.
