Nanosized Ca(OH)2 particles having different physical characteristics e.g. surface area, degree of crystallinity, have been prepared. Endothermal doublets present in the thermoanalytical spectral information reflect differences in the degree of cryst

Equations are developed to describe the combined effect of diffusion and adsorption of water and methanol vapor in hydrated cement paste. The dynamic equation of flow is obtained by equating the space derivative of the spreading pressure of the adsor

The thermal decomposition of different polymorphs of Ca(OH)2 with varying degrees of crystallinity and surface area was investigated. The nitrogen surface area values ranged from 3.7 to 31.1 m2/g. The presence of two separate and distinct thermal dec

The presence of at least two different forms of Ca(OH)2 is confirmed by the results of a thermoanalytical study on the decomposition and re-hydration characteristics of Ca(OH)2. The study comprised a series of differential scanning calorimetry (DSC)

The annual expenditure for repair and rehabilitation of concrete structures exceeds 50 percent of the total construction costs. It is expected that this trend will continue at least to the year 2000. The large market for repair materials and speciali
