Microstructural changes caused by carbonation of cement mortar

Cement and Concrete Research, 2001
The change of specific surface area and pore size distribution due to carbonation of an ordinary Portland cement mortar is investigated. The adsorption of water vapor on noncarbonated and well-carbonated cement mortar is measured in order to evaluate the

The effect of fillers on strength of cement mortars

Cement and Concrete Research, 1977
Abstract The effect of three fillers (ground limestone, dolomite and basalt) on the strength of cement mortars was studied on 1:2.75 mixes having a w/c ratio of 0.70. The filler content ranged from 10 to 40% of the cement weight and their fineness (specific surface) from 1,150 to 11,200 sq. cm per g. Results confirmed earlier conclusions that fillers

Chloride ingress in cement paste and mortar

Cement and Concrete Research, 1999
In this paper chloride ingress in cement paste and mortar is followed by electron probe microanalysis. The influence of several paste and exposure parameters on chloride ingress are examined (e.g., water-cement ratio, silica fume addition, exposure time, and temperature).

Electrical conductivity of Portland cement mortars

Cement and Concrete Research, 1996
Abstract Mortars containing volume fractions of aggregate less than 0.35 were prepared at w c = 0.35, 0.40, and 0.45 and hydrated for 1, 14, and 28 days. Mortar electrical conductivities were determined by impedance spectroscopy, and the experimental data were fitted to the polynomial, where, σm is the mortar σ m = A + B
