BÉTON OU MORTIER LÉGER STRUCTUREL, SON PROCÉDÉ DE FABRICATION ET SON UTILISATION EN TANT QUE BÉTON AUTO-PLACANT
Disclosed is a structural lightweight concrete or mortar composition which, in the fresh state, includes an hydraulic binder, aggregate, and water, characterized in that the composition includes: an hydraulic binder content including cement and optional additions, which is greater than or equal to 280 kg/m3 of fresh concrete, coarse aggregate and/or fine aggregate, a volume proportion of at least 70% of the fine and/or coarse aggregate consisting of fine and/or coarse lightweight particles, the actual dry density of which is between 800 and 1,600 kg/m3, the total amount of aggregate being greater than or equal to 500 L/m3 of fresh concrete, a superplasticizer, at least one thickening agent, and effective water in an effective water/hydraulic binder weight ratio of between 0.40 and 0.65. The composition can be used for producing a self-placing lightweight concrete.
