Limestone-Calcined Clay (LC2) as a supplementary cementitious material for concrete

In this work, limestone-calcined clay (LC2) is studied as an alternative supplementary cementitious material (SCM), combining two widely available resources – calcinated kaolinitic and limestone, to partially substitute portland clinker. The primary goal assess the potential of LC2 produce moderate high strength concretes with design compressive strengths 20 50 MPa. For purpose, 27 mixes were prepared a range binder contents water-binder ratios, performance was benchmarked against those having fly ash (PFA). addition quantification concrete resistivity, life cycle assessment performed for considering typical situation in India. efficiency made LC2, PFA ordinary cement (OPC) analyzed using energy intensity index (eics) apathy (A-index) sustainability indicators. This framework establishes insights on influence It concluded that 45% replacement level, w/b≤0.45 content lower than 400 kg/m3 possess highest potential, among here.
