Use of low-carbon cement in the preparation of masonry mortars for building restoration

Abstract

This research work deals with the use of low-carbon cement SIG B45 (SIG B45 is LC3 cement produced at the Siguaney factory) in the manufacture of masonry mortars according to the dosage established by the NC175:2002 Cuban standard for both types II and III mortars. The experimental part focused on the use of SIG B45 cement, sand from “El Purio” and “Arimao” pit and PP-25 cement as a pattern sample. Tests carried out included flexural-compression strength, water absorption, water permeability, open porosity and bonding. Results attained from tests validate the use of LC3 cement in masonry mortars.
