摘要: Abstract In the clinker production process, main component of Portland cement (PC), large amount CO 2 are emitted into atmosphere. The use calcined kaolinitic clays as supplementary material is an alternative to mitigate environmental impact. this paper, influence replacement PC by two (15 and 30%), with high content metakaolinite different reactivity was studied. Calcined were characterized, pozzolanic activity usingFrattini test, compressive strength, rate water absorption (sorptivity), assemblage hydration products pore size distributionwere determined at28 days. results show that percentage (30%) very reactive improves mechanical behavior durable parameters compared those obtained for plain
