For the design of mortar mixes for filling root piles, the Brazilian standard NBR 6122, establishes a minimum compressive strength of 20 MPa (28 days), minimum cement content of 600 kg/m3 and a water to cement ratio between 0.5 and 0.6 and allows the use of water-reducing admixtures; however, the definition of a minimum cement con...
View ArticleIn the case of rock-fluids interaction, numerous studies have mainly focused on field and numerical simulations regarding the existence of toxic gases and investigations about the possibility of gas burst. This paper is related to the development of experimental investigations for granite formations on samples obtained from Creighton mine, Sudbury, Cana...
View ArticleThis paper presents a study on the compressibility of municipal solid waste (MSW) by means of a field survey in Valdemingomez Landfill in Madrid, Spain. Organic matter content was 59%, there was no waste segregation and field compaction, nor internal drainage systems for gas and leachate. Solid waste management changed significantly since then in Madrid...
View ArticleThe literature review of previous studies and the analysis of observations and knowledge gathered in Africa, as well as regional experience in Brazil, India and Australia on the influences of texture, grain size distribution and mineralogy conditions on the stability of materials used in pavement base have shown that the mechanical behaviour of lateriti...
