Statement of the problem. Preparation of high-strength foam concrete in construction allows for energy and resource conservation. Water covers more than 50% of their dense component and on its properties depend strongly on structural properties of foam concrete, is not fully explored.
Results. The effect of mixing water of low temperature on the structure and properties of constructive penofibrobetonov. Recommendations on the account in the calculation of reinforced concrete elements elevated structural properties and deformation diagrams penofibrobetonov by mixing water setback.
Conclusions. Using low temperature mixing water improves the structure, increases the strength, deformability and elastic modulus, as well as changes of the deformation diagram fibropenobetonov.

The influence of non-multi - repeated loads on columns of keramzito fibrobetona. Comparative results of tests Depends on the flexibility of columns, the eccentricity of the external force, the coefficient of reinforcement options and loading. The obtained results suggest that repeated loading nemnogokratno increase the carrying capacity of columns, compared with a single loading. This is especially effective for columns with low flexibility and small eccentricities external force.
