Currently one of the major problems in the area of construction and specifically
in Civil Engineering, is the high portland cement production globally that is
reflected in the negative environmental impact. However, this production is
necessary for the economic development of society and large civil works, so
there is a need to have sustainable materials that reduce this problem. The
ancient Romans used volcanic ash, known as pozzolan, which contains silica and
alumina, which when combined chemically with lime resulted in the so-called
pozzolanic cement (obtained in Puzzuoli, near Vesuvius). Previous studies where
different agricultural residues of the sugar industry were used, such as cane
bagasse ash (CBC), demonstrate its potential use as a pozzolanic material
according to the properties they possess. The CBC, once pulverized and in the
presence of water, reacts chemically with the calcium hydroxide that provides
the hydration to portland cement, to form compounds with cementing
properties. The mortar made with these materials was designed according to
standard ASTM-C-109/2002, with a cement-sand ratio of 1: 2.75. Three different
mortar mixtures were prepared, one control mortar (cement-sand-waterfluidizing)
and 2 modified mixtures, one mixture with addition of CBC in 5% and
the other with substitution of CBC in 5%, based on the cement mass. The
objective is to determine the pozzolanic reactivity of this agroindustrial waste by
comparing the resistance to compression and indirect stress and thus be able
to recommend it for the production of mortars. The study of the CBC as a
pozzolanic material demonstrates the improvement of the physico-mechanical
characteristics of the mortars, and at the same time contributes to the reduction
of the environmental impact generated by cane bagasse ash.
