【 摘 要 】

Foam concrete is classified as a lightweight concrete. It is a cement mortar in which air-voids are entrapped by a foaming agent. Its practical application is mainly limited to nonstructural material. For many years, the application of foam concrete has been limited to backfill of retaining walls, insulation of foundations, roof tiles and sound insulation. However, in the last few years foam concrete has become a promising material also for structural purposes. When the marginal loads are reached, all of alveolar concrete, included foam concrete, is destroyed without previous deformations. So, the main condition for the safe and reliable foam concrete use in structure elements is to increase its strength characteristics for short and long loads. Span constructive elements of foam concrete are performed as usual, reinforcement is ensured by a steel armature of a smooth or periodic profile. Experimental and theoretical research of comprehensive light concrete span elements and other types of reinforcement, their use in the methods of calculation, such as constructions with unconventional reinforcement, are not explored and used enough. One way to solve the problem is to replace conventional reinforcement by unconventional one (for example, organic or biological materials, different kinds of mesh). The results of experimental research of foam non-aerated concrete elements, the features of their work under the load are presented in this article. In this article, methods of increasing the strength of non-autoclave foam concrete using secondary waste are proposed. The results were compared with the results of tests of unreinforced elements.
