Construction Defects 2INTRODUCTIONThis research paper is about a defect in the construction material that is situated around Sydney region. Some of the subtopics considered in this research include the properties of the construction material, the function of the material, description of the defect, and the solution to the defect. The material used in the construction of the building being evaluated is concrete construction material. The concrete construction material is a composite material which is composed of coarse and fine aggregate bonded together with cement paste that hardens after sometimes[ CITATION Pro13 \l 1033 ]. The figure below shows the concrete construction material and also the defect:Figure 1: Concrete Construction material and the defectThe concrete construction material above is composed of cement and also other cementitious materials such as chemical admixtures, water, fine aggregate such as sand, fine aggregate such asgravel, slag cement, and fly ash. This construction material is prepared by mixing aggregate together with water and dry Portland cement, the mixture forms a slurry fluid which can be moulded and poured into the shape of the wall shown in the figure above. A chemical reaction

Construction Defects 3known as hydration takes place between the concrete, cement, and water usually changes from a plastic state to a solid state after approximately 2 hours[ CITATION Pet121 \l 1033 ]. The function of Concrete Construction MaterialConcrete possesses numerous features that assist in making the structure to be sustainable. This construction material can be characterized by low tensile strength, high compressive strength, economy, durability, and strength. This construction material helps to prevent flooding since it is known to be water resistant and this property is important to the structure since it prevents the occurrence of floods around the structure. The concrete is also fire-proof and this structure is not affected by the effects of fire since it cannot burn and also it does not produce any fumes that are toxic when it burns[ CITATION Uni09 \l 1033 ]. The concrete material also makes the structure to be more durable without wearing out due to its structural strength. Another function of concrete construction material is its thermal mass efficiency which makes the structure to be more energy efficient due to the capability of theconcrete to retain heat hence reducing the power bill require during air conditioning. The workability of the concrete material also makes it easy to be mixed and subsequently handled during the repair of the damaged parts of the structure[ CITATION Awa10 \l 1033 ]. Honeycomb Defect in ConcreteHoneycomb defect is the hollow cavities and spaces left in concrete mass inside the concrete mass of on the surface of the concrete mass which is caused by the mortar not filling thevoids between the particles of coarse aggregate. There are three types of honeycombs defects, these include small size honeycombs which have a depth less than 25mm, moderate size honeycombs which have a deeper depth than 25mm but there is no exposure of steel bars, and
