Title
(EN) UTILIZATION OF HEAVY OIL FLY ASH TO PRODUCE CONTROLLED LOW STRENGTH MATERIAL FOR BACKFILLING APPLICATIONS
(FR) UTILISATION DE CENDRES VOLANTES DE PÉTROLE LOURD POUR PRODUIRE UN MATÉRIAU À FAIBLE RÉSISTANCE CONTRÔLÉE POUR DES APPLICATIONS DE REMBLAYAGE
Abstract
(EN)
A controlled low strength material has constituents that include a cement, an aggregate, a heavy oil fly ash, and a water. The controlled low strength material has a compressive strength in a range of 300 kPa to 2.1 MPa. In certain embodiments, the heavy oil fly ash can be part of a heavy oil fly ash slurry.
(FR)
La présente invention concerne un matériau à faible résistance contrôlée qui a des constituants qui comprennent un ciment, un agrégat, des cendres volantes de pétrole lourd et de l'eau. Le matériau à faible résistance contrôlée a une résistance à la compression dans une plage de 300 kPa à 2,1 MPa. Dans certains modes de réalisation, les cendres volantes de pétrole lourd peuvent faire partie d'une bouillie de cendres volantes de pétrole lourd.
