The use of carbon nanoclusters as additives in concrete in order to improve its physical and mechanical properties is a future branch of the building technique and of the interior design. The advantage of carbon nanoclusters consists in a high surface energy and a very strong interaction with concrete ingredients. The authors have shown that introducing micro-doses of nanoclusters in concrete, its thermal properties improve, especially the thermal transfer coefficient [1-2]. This leads to a reduction in the cost of insulating buildings and rooms, favouring the use of low-weight interior decorations by applying to the vertical wall, together with the thermal insulation effect. To obtain carbon nanoclusters, the soot obtained from the combustion of fusible substances was used [3].
