Production of Durable Concrete with a Mineral Addition Blend of Calcined Clay-Limestone-Gypsum (LC2) and Portland Cement

摘要

This article presents the evaluation of different concrete formulations pro-duced with LC3 cement and LC2 mineral addition. The same includes studies of the properties of fresh and hardened concrete and a preliminary evaluation of its dura-bility. LC3-50 2:1 cement-milled by intergrinding was used, Atenas Cements were combined with LC2 mineral addition, 90% Atenas Cement with 10% SikaFume. Atenas Cement, produced industrially at the Cuenca Ecuador plant, was used as a reference and the concrete was formulated for a dosage of certified concrete, for resistance of 35 MPa.
