Concrete is the mixture of cement, aggregates, water with or without admixtures which harden to form artificial hard rock. Concrete is the one of the important and popular construction material,  concrete is used in construction of different structures such as Dams, Retain walls, roads, buildings, pipes and tanks. Concrete can be in two States or forms that is plastic state and in solid state. Concrete in plastic state is called fresh concrete , this concrete is in liquid or semi solid form, able to flow and has not yet set. Concrete in solid state is called hardened concrete , this is when it has changed  from liquid or semi solid form into solid form. Important characteristics of the Concrete that make it mostly and widely used are the following Concrete can be moulded into different shapes with significant strength . Economical Concrete of required properties can be produced for different projects . The two important tests There are two important tests that must be carried ...

In construction industry different structures are built, the built structures can be categorized with accordance to construction materials, here we can have steel structures , timber structures and concrete structures. Concrete structures are the one which most of its structural parts made from concrete material , concrete is the most and widely used material due to its ability to be moulded into different shapes , and having wide range of characteristics (economical concrete of variety properties can be produced for different requirements). Concrete has high compressive strength , that make concrete made structures to have high capability to withstand compression, cement concrete has low tensile strength that make it unsuitable for structures subjected to high tension. Due to some weakness and properties of cement concrete, it is reinforced so as to produce a structure with required properties. Concrete can be reinforced by different kind of materials in different ways per given a...

  FORMWORK These are temporary sometimes permanent structure that are formed during construction process, that are used as moulds for concrete so as to attain the concrete of desired shape and size when hardened. In construction industry formwork of different shapes and sizes for different structures are constructed such as beams, columns, slabs, channels, culverts , where by formwork of different structures are made through different ways. In common, formwork are composed by the following components soffits, struts and stiffeners (cleats, wales, studs, ties and collar) Where by each component has the same function in most of formwork for different structures Soffits these comprise of surfaces either horizontal or vertical on which the concrete is poured, soffits should be in such way that they provide concrete with smooth finish. Strut or braces these are linear member made of timber or steel mostly inclined or horizontally provided to support and increase the rigi...
