The phase constitution of alite in portland cement clinker highly depends not only on the chemical composition of a raw mix but also on the kinetics of crystallization from the interstitial melt. From the melt of high supersaturation alite can be crystallized so quickly as to take up foreign ions i

โฆ Synopsis
The effects of type of cement, initial water:cement ratio, initial porosity, and curing time on the compressive strength of molded cement pastes are described. The mathematical dependence of the compressive strength on the post-curlng porosity, the relationship between compressive strength and splitting tensile strength~ and the dependence of both the compressive and the splitting tensile strength on the specimen sizes are discussed.

Compressive strength varied from I to 2.3 times the water-saturated strengths and was ordered
The Authors describe an attempt of correlating, by means of the linear regression analysis, the chemical composition of the Portland clinker to the compressive strength of blast furnace slag cements. The investi gation shows Chat the main constituents of the clinker do not influence the compressive
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 i0 to 40% of the cement weight and their fineness (specific surface) from 1,150 to 11,200 sq.cm per g. Results
