Abstract:

Development of sustainable technologies for production of porous, energy effective and innovative product such as foam concrete is in accordance with the requirements of sustainable development. In the present investigation foam concrete, produced applying mixing technology with effect of cavitation, with properties characterized by a low density and specific pore structure, without additional thermal treatment, has been developed. The basic properties of foam concrete, such as water absorption, compressive strength, density and thermal conductivity have been investigated in depending from the mixing parameters, kind and amount of additive. Experimental results showed less values of water absorption and less thermal conductivity of foam concrete comparing to aerated gas concrete. Using of modifying admixtures is the way to improve compressive strength and decrease value of water absorption of foam concrete.
