The drying step of hydraulic-bonded refractory castables is usually carried using conservative and long heating schedules, in order to preserve the microstructure of dense ceramic linings and inhibit explosive spalling ...

The aim of this study was to evaluate the properties of briquettes made from charcoal fines bonded with paraffin. To prepare them were used three fractions of fine coal (20, 35 and 60 mesh) and a binder, the paraffin. ...

The triaxial compressive response of bituminous mixes with volume fractions of aggregate in the range 52 to 85% was investigated over a wide range stresses and strain rates. The types of loadings considered include triaxial ...

The recent development of refractory castables for high temperatures applications are closely related to binders technology, especially those presenting superior performance and installation properties. The calcium aluminate ...

Ceramic encapsulation for refractory material residues has been studied by a chemically bonded ceramic technique, using a new binder system based on special potassium and magnesium phosphate. Comparison among this technique ...

Pervious concrete is a construction material widely used in pervious pavements. Pozzolanic materials replacing partially Portland cement can improve mechanical and hydraulic issues associated with the use of pervious ...

Road transport is extremely important for the development of Brazil and the increasing vehicular traffic in the transport of people gives an excessive dependence on roads. The quality of the road network of the country ...

Different pathologies may arise on a wall finish if this is applied on a hemp-based rammed wall that is not completely dry. By simulating uneven drying and early-rendering of load-bearing and non-load-bearing hemp concrete ...
