Recent research has recognized limestone calcined clay cement (LC3) a promising sustainable cementitious material. While LC3 could be used in a wide range of applications. it is important to explore its feasibility in developing (ultra-)high performance concrete. In this paper we attempt to produce ultrahigh performance LC3 concrete (UHP-LC3). https://safeersappliancers.shop/product-category/aeg-ike84441fb-maxisense-78cm-touch-control-four-zone-induction-hob/
