Resumo:
Due to the increase in world population, it increases the effect consumption. The
industries produce an accelerated pace, which also produces a high amount of
waste. Many of these wastes are disposed of improperly, causing losses to the
industries and the environment. Due to these factors, several researches are being
developed, aiming at the reuse or recycling of such waste. One of these is the waste
from the textile industry, also known as textile sludge. This research aimed to
characterize and study the incorporation of textile sludge in the composition of
mortars. We made the following analysis: thermogravimetry, vibrational spectroscopy
of infrared absorption, X-ray diffraction, chemical analysis, particle size analysis, and
testing of compressive strength. In mortars used the feature 1: 2: 9 and the
percentages of clay, 0%, 5%, 10%, 15% and 20% with curing times of 7, 14 and 28
days. The percentage of sludge were added to the mortar as substitute material for
cement, after undergoing heat treatment in a muffle furnace at a heating rate of 10 °
C / min and settling time of 2 hours at 400 ° C, 450 ° C, 500 ° C, 550 ° C and 600 ° C.
The compressive strength tests indicated that all mortars had results that meet the
minimum stipulated by the ABNT norms in force. It was also observed that the
compositions of mortar to cure 28 days and incorporation of textile sludge calcined at
a temperature of 600 ° C showed the best results of compressive strength. Physicalchemical
characterizations carried out concluded that the raw materials presented
chemical compatibility and thermal stability enough for incorporation in mortar.
