HARDENED PORTLAND CEMENT PASTES OF LOW POROSITY

EXCELLENT WORKABILITY AND SATISFACTORY SETTING TIMES WERE OBTAINED BY THE USE OF ADDITIVES WITH AS LOW WATER-CEMENT RATIO AS 0.2. BECAUSE OF THE LOW POROSITY, MUCH HIGHER COMPRESSIVE STRENGTHS AND MUCH LOWER DIMENSIONAL CHANGES WERE OBTAINED. THE SET RETARDATION AND THE OBTAINING OF GOOD WORKABILITY WERE ACCOMPLISHED BY THE USE OF CALCIUM LIGNOSULFONATE TOGETHER WITH POTASSIUM CARBONATE. THE NATURE OF THE GRINDING AID ALSO PLAYED AN IMPORTANT ROLE. DIMENSIONAL CHANGES OF 0.2 WATER-CEMENT RATIO PASTES, HYDRATED AT 25 C FOR ONE DAY AND FOR 28 DAYS INDICATE THAT VOLUME CHANGES CAN BE GREATLY REDUCED BY USING LOW-POROSITY CEMENT PASTES. /AUTHOR/
