A self-levelling mortar or micro-concrete can be manufactured, especially in situ, by mixing cement and other ingredients of a mineral nature such as sand or gravel with water to obtain a rheology which enables the substance to flow like a liquid. A dispersion agent containing a 90% proof alcohol, sodium sulphite, iodine and a quantity of water needed to obtain a good level of homogeneity is added to the material. The additive is made, for example, from 10 parts alcohol, 40 parts sodium sulphite, 50 parts water and an iodine, and it is added at a rate of four litres to each cubic metre of the mortar or micro-concrete. |
