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.

Formulation of the problem. One of the major technological challenges is to get fiber-reinforced concrete with a uniform (aggregated) distribution of the fibers in terms of concrete, on which depend significantly on design and performance of the fiber-reinforced concrete. Results. Proposed shuttle technology making fiber-reinforced concrete with aggregate distribution of the fibers, studied the change of its structural properties, developed design recommendations for the evaluation of its strength and deformation characteristics and strain diagram in compression and tension. Conclusions. Experimental studies suggest a positive effect of the proposed technology on the properties and characteristics of fiber-reinforced concrete with aggregate distribution of the fibers. Keywords: fiber concrete with aggregate distribution of the fibers, the strength and deformation characteristics, the strain diagram.
