Abstract
A treatment process for the production of a hydraulic composition with entrained air including at least one admixture and a constituent including carbonaceous materials, the process including: obtaining a representative value of the adsorption of probe molecules by the carbonaceous materials; and producing the hydraulic composition or treating the constituent with a quantity of admixture which depends on the value.
Claims18
A treatment process for the production of a hydraulic composition with entrained air comprising an inerting agent and a constituent comprising carbonaceous materials, the process comprising:
- obtaining a representative value of an adsorption of probe molecules by the carbonaceous materials;
- and
- producing the hydraulic constituent or treating said constituent with a quantity of inerting agent which depends on said value, wherein the inerting agent comprises at least one polymer comprising at least one chain having hydrophobic end groups and an intermediary hydrophilic group between the hydrophobic end groups,
- wherein said process further comprises
- measuring a first supplementary value which is representative of the adsorption of the probe molecules for each first portion from at least two first portions of a supplementary reference constituent with different quantities of supplementary reference carbonaceous materials;
- producing, for said each first portion, a supplementary reference hydraulic composition with the supplementary reference constituent of the first portion, said supplementary reference hydraulic composition obtained for said each first portion being separate from the hydraulic composition to be produced;
- determining, for said each first portion, a quantity of inerting agent to be added to the supplementary reference hydraulic composition to reach a specific property;
- measuring a second supplementary value which is representative of the adsorption of the probe molecules for each second portion from at least two second portions of said constituent having different quantities of said carbonaceous materials, said constituent to be used to produce the hydraulic composition;
- determining a correction coefficient from the first and second supplementary values;
- determining, for said obtained representative value, an estimated quantity of inerting agent to be added to the hydraulic composition comprising the supplementary reference constituent;
- and
- determining the quantity of inerting agent to be added to the hydraulic composition comprising the constituent from the estimated quantity of inerting agent and the correction coefficient.
