For some time the cement industry has been seeking procedures to effectively lower the higher energy costs involved in cement manufacture. Timahdit oil shale and Jerada coal waste could potentially be used as alternative raw materials to produce clin

One of the chief causes of cement and concrete deterioration is the loss of durability prompted by sulphate attack. The existing standards call for long test periods (2- 12 months). Thermodynamic modelling is a particularly appropriate technique for

The water- and dirt-repellent properties of fluorinated products have been used primarily in waterproof coatings. The development of new materials or the definition of new functions for existing substances may extend the possible application of these

The pozzolanic reaction of nanosilica in contact with C3S was monitored via isothermal conduction calorimetry. Since that reaction is affected by heat, its variations with curing temperature (25, 40 and 65 °C) were also analysed. The findings showed

Volcanic pozzolans owe their pozzolanic activity chiefly to the presence of vitreous or zeolitic material rich in SiO2, and Al20y compounds that react with the portlandite produced during cement hydration to generate amorphous gels with cementitious

This paper compares industrial clinker and cement produced using conventional and alternative fuels (animal meal, tyres or a mixture of the two). The results show no relevant differences in terms of mineralogical composition between the clinker manuf

Sulphation of mortars and concretes is a function of diverse environmental factors (SO2 aerosol, temperature, etc) as well as some material characteristics. One of the phases that could be formed as consequence of the sulphation of the hydraulic bind

This work discusses the results from accelerated tests intended to investigate the ways the different curing methods affect the carbonation of calcium aluminate cements pastes (CAC). The research was focused on the mineralogical composition of hydrat

The effect of incorporation of BaCO3 in portland cement hydration has been studied. From this study it is inferred that presence of BaCO3 in cements makes them require a higher quantity of mixing water. However, mechanical resistances do not seem neg
