Determination of technical characteristics of traditional foam concrete and foam concrete with mineral fiber

Abstract

Foam concrete is currently enjoying its popularity due to a number of advantages, such as non-toxicity, reduction of thermal insulation costs, noise absorption. Nowadays at the state level the issue of utilisation of waste of different nature and increasing the quality of recycling is constantly being considered. Also a big task is set in the scientific sphere of the country on recycling of utilised waste in different sectors and especially in the construction sector. There are numerous grant programmes in the scientific field, which are aimed at the use of waste in the industrial and construction sector of the country. This paper is devoted to the study of the qualitative characteristics of traditional foam concrete and foam concrete with the addition of mineral fibre. In the construction sphere the main thermal insulating material in the form of mineral boards is widely used and there are factories for the production of basalt boards in the course of production of which there is a lot of basalt waste. Tests have been carried out according to the standard methodology in order to determine the strength and density of the finished product. According to the test results it was determined that the pore structure and strength is uniform over the whole surface of the blocks. It was also determined that the specimens with fibre showed a strength of more than 50% compared to conventional foamed concrete. This work will be a good direction for further in-depth study on the utilisation of basalt slabs in construction.
