Production of cell concrete blocks using cocoa fatty acids and foundry wastes

T
he northern region of the State of Rio Grande do Sul
is an important metal / mechanic industrial pole, with
an extensive and varied equipment portfolio, especially
the manufacture of agricultural implements. In foundries
s parts used in the manufacture of agricultural machinery
a lot of sand are used, generating waste in accordance
with standard NBR 10004/2004, which deals with the
classification of solid waste as their potential risks to the
environment and health waste sand is classified as class
II A. This class includes non-hazardous and non-inert
waste. Their environmentally sound disposal in controlled
or sanitary landfills represents an important expense in
the cost sheet and requires careful management for the
generating industries that are directly responsible for
incidents and accidents and co- responsible for possible
future environmental liabilities, even with landfill toilets
paid. Specifically, this work evaluated the possibility of
using the casting sands in the manufacture of cellular
foam blocks (BCCE), their inertization and consequent use
as building blocks in civil construction. The production
methodology will be based on models studied and already
published in papers and scientific articles, laboratory tests
and also in industrial format. In previous bench studies,
after characterization of the casting sand as its grain size
curve, DRX, DFX, the analysis of the foam composition,
the particle size of the residue, the water content and the
mixing time. The BCCE component materials are sandcast
residue, collected in the KUHN DO BRASI industry, foam
prepared with coconut fatty acids, drinking water quality
and cement as a binding agent. In the bench tests, 36 test
specimens, cylindrical in size, 50 mm in diameter per 100
mm in height, with different volumes of incorporated air,
were divided into three groups. The samples were left for
28 days at room temperature, in the curing process, and
after analysis for the compressive strength, density and
distribution of the air bubbles.
