field tests
field tests of the technology have been conducted with DDT on the surfaces of concrete slabs. A water emulsion of DDT was
sprayed to get a concentration of about 1-2 g/m
2
on the concrete slab. Then the surfaces of the concrete slabs were pulverized
by water solution of NCMC (Ti) at a concentration of 2 mg/l to get a surface density of about 0.01 g/m
2
for nanocompositions.
