The issue of spent battery electrolytes recycling in the process of
construction material production is considered in this article and also
the negative impact of such wastes on environment. Modern methods of
processing as spent batteries and their electrolytes are analysed. In
this article proposed to recycle spent acid battery electrolyte,
applying it as additional component of the mixing liquid for phosphate
systems, featured by high mechanical properties, heat and acid

The calculation of a pile
grillage quay, as a frame with rigid anchored legs, using in technical
literature and normative documents, is called a method of Gersevanov.
The transformation of a manual calculation to a computer calculation
almost preserves an existing design diagram.

of high-dispersive additives as structure modifiers is one of the most
effective instruments of cement composites required technical
exploitation characteristics increase nowadays. However, use of
high-dispersive powders is complicated by the fact that their particles
are consolidated into aggregates.

paper is devoted to earned value management, it describes the basic
tools of this method, particular attention is directed to the
indicators of the deviation of the time of the project. Also reasons
for not using the method in practice are revealed.

composite board materials with woodchip fillers and nonprocessable flax
and cotton processing waste based on the thermosetting binder matrix
can be used as construction material for thermal insulation purposes.
Research methods of temperature and humidity change influence on
adhesive-bonded board materials’ qualities are reviewed.

This article examines the justification for using one-dimensional
structural models in the analysis of the thermo-stressed state in
massive concrete and reinforced concrete structures during the building
period. The paper presents calculation results for the thermo-stressed
state in massive foundation slabs with different planform dimension

scheme for statically determinate flat lattice-type truss is
investigated. The truss has two supports and uniformly loaded at the
upper zone. Analytical dependencies of the deflection of the structure
and displacement of the movable support from its size, load and number
of panels are obtained.

filtration is one of the main methods for individual and local water
supply systems. Track-etched membranes are among the types of membranes
that allow to obtain high quality purified water due to their high
selectivity. Ensuring the durability of track-etched membranes is one
of the topical issues on their use.
