Utilization of Iraqi Metakaolin in Special Types of Concrete: A Review Based on National Researches

Portland cement concrete is the most commonly used construction material in world for decades. However, searches technology are remaining growing to meet particular properties related its strength, durability, and sustainability issue. Thus, several types of have been developed enhance performance. Most modern contain supplementary cementitious materials (SCMs) as a partial replacement cement. These either by-products waste such fly ash, slag, rice husk silica fume or from geological resource like natural pozzolans metakaolin (MK). Ideally, utilization SCMs will performance, minimize environmental pollution mitigate drawbacks production attributed highly CO2 emission. In general, MK's ultra-fineness high pozzolanic activity exhibited remarkable performance terms strength durability. filler effect, acceleration hydration, reaction with calcium hydroxide (CH) main factors influencing material. Therefore, numerous researches undertaken on inclusion MK mortar (free-cement concrete) geopolymer concrete. This paper reviews some previous native effect using Iraqi different The standpoint this review guide researchers importance local highlight missing toward completing comprehensive understanding incorporation Iraqi-metakaolin technology.
