Metakaolin is considered as one of most promising microfiller with pozzolanic properties in concrete industry. Metakaolin is a high value product obtained from kaolin clay calcined at high temperatures with also can be used in ceramic industry; therefore, its application in concrete industry is limited due to high price of the product. In present research metakaolin containing by-product (wMK) was studied as a cement replacement in high strength self compacting concrete (SCC). Obtained waste material derives from the foam glass granule production plant where kaolin clay is used as releasing agent during heating process and in the end metakaolin with glass impurities is obtained as by-product. In present research 5 to 15 wt.% of cement was replaced by wMK. A constant water amount was used for all mixtures and workability (>600 mm by cone flow) was ensured by changing the amount of superplasticizer. Compressive strength was tested at the age of 7, 28 and 180 days. To determine durability of SCC the chloride penetration was tested according to NT BUILD 492 and freeze-thaw test according to LVS 156-1:2009 annex C respectively. The results indicate that cement replacement by wMK did not affect the strength of SCC significantly. At the age of 28 days SCC with 15 wt.% of wMK reached compressive strength of 70 MPa comparing to 68 MPa to reference mixture. The chloride penetration test results indicated that the non-steady-state migration coefficient of reference samples was reduced 3.5 times and it was concluded that SCC resistance to chloride penetration can be increased by incorporation of wMK in mixture composition. Freeze-thaw test results indicated that obtained SCC can withstand at least 300 freeze-thaw cycles without surface damage and weight loss. It was concluded that up to 15% of cement can be replaced by metakaolin containing waste without strength loss and the durability of SCC could be increased.
