t is disclosed herein a coating material for building elements. It contains raw materials (pumice of 0-2 mm of granularity in proportion of 70% m3 and brawn portlant cement in proportion of 23% m3), subsidiary materials (hydrate lime in proportion of 5% m3, calcium lignosulphonate in proportion of 0,02% m3 and concrete composition in proportion of 1,98 % m3). The use of admixtures (subsidiary materials) depends on the building material to be covered. The advantage of the invention is that, compared to traditional materials, it reduces the whole weight of the materials in use and exhibits fireproof, heat insulating and sound-insulating properties. |
