| Title of the article | Optimization of structures of metal concrete on the aluminum binding |
| Abstract. | Among the materials considered for use in the field of special construction, composites made by means of the metal binding and granulated fillers – metal concretes can be represented perspectively. Effective use of such concretes is reached in the conditions of influence of cyclic temperatures, ionizing radiation, dynamic loadings. Properties of composite materials and, in particular, metal concretes, directly depend on a quantitative ratio of making components and their qualitative characteristics. By the systematized change of these or those structure-made parameters it is possible to reveal their values at which optimum properties of a composite as a whole are reached. Results of research of metal concretes are given in the present article with a matrix from aluminum binding the AL2 brands. As fillers diabase and basalt rubble and claydite gravel of various fractions were used. By means of methods of mathematical planning of experiment by change of the content of filler and the size of its fraction optimum zones of factorial space with the greatest durability of metal concrete for each type of filler were revealed. So, to optimum durability indicators on compression for metal concrete on diabase rubble there corresponds the raised maintenance of fraction of 2,5-7 mm (at durability about 270 MPas); on basalt rubble – at the contents more than 60 % of fraction of 2,5-5 mm (durability about 270 MPas is also reached); on claydite – at the maintenance of fraction of 2,5-5 mm in limits from 40 to 60 % (durability of 60-70 MPas). |
